+# Contributors Guide
+
+Please read and understand the contribution guide before creating an issue or pull request. We would like to thank [Nishad TR](https://github.com/nishad) for their contributor's guide, upon which we based ours.
+
+## Etiquette
+
+This project is open source, and as such, we (the maintainers) give our **free time** to build, maintain and **provide user support** for the CCExtractor program. We make the code freely available in the hope that it will be of use to other developers and users. It would be extremely unfair for us to suffer abuse or anger for our hard work.
+
+Please be considerate towards the developers and other users when raising issues or presenting pull requests.
+
+It's the duty of the maintainer to ensure that all submissions to the project are of sufficient quality to benefit the project. Many developers have different skillsets, strengths, and weaknesses. Respect the decision of the maintainers, and do not be upset or abusive if your submission is not used.
+
+## Viability
+
+When requesting or submitting new features, first consider whether it might be useful to others. Open source projects are used by many developers, who may have entirely different needs to your own. Think about whether or not your feature is likely to be used by other users of the project.
+
+## Procedure
+
+**Before filing an issue**:
+
+- Attempt to replicate the problem, to ensure that it wasn't a coincidental incident.
+- Check to make sure your feature suggestion isn't already present within the project.
+- Check the pull requests tab to ensure that the bug doesn't have a fix in progress.
+- Check the pull requests tab to ensure that the feature isn't already in progress.
+
+**Before submitting a pull request**:
+
+- Ensure that your submission is [viable](#viability) for the project.
+- Check the codebase to ensure that your feature doesn't already exist.
+- Check the pull requests to ensure that another person hasn't already submitted the feature or fix.
+
+## Technical requirements
+
+- Before Submitting your Pull Request, merge `master` with your new branch and fix any conflicts. (Make sure you don't break anything in development!)
+- Commit Unix line endings.
+- Make sure to reasonably test your code. We have a sample platform that runs a test-suite for you, but it only covers a general set of tests.

+- What where the used arguments? `-autoprogram`
+
+**Video links**
+
+Please make the affected input file available for us (no screenshots, those don't help!). Public links to Dropbox, Google Drive, etc, are all fine. If it is not possible to make it available publicly, send us a private invitation (both Dropbox and Google Drive allow that). In this case we will download the file and upload it to the private developer repository.
+
+Do *not* upload your file to any location that will require us to sign up or endure a wait list, slow downloads, etc. If your upload expires make sure you keep it active somehow (replace links if needed). Keep in mind that while we go over all tickets some may take a few days, and it's important we have the file available when we actually need it.
+
+**Additional information**
+
+{issue content here, replace this line with your issue content}
+
+PS: Make sure you set an alert in GitHub so you get notifications about your ticket. We may need to ask questions and we do everything inside GitHub's system.

+CCExtractor is a tool used to produce subtitles for TV recordings from almost anywhere in the world. We intend to keep up with all sources and formats.
+
+Subtitles are important for many people. If you're learning a new language, subtitles are a great way to learn it from movies or TV shows. If you are hard of hearing, subtitles can help you better understand what's happening on the screen. We aim to make it easy to generate subtitles by using the command line tool or Windows GUI.
+
+The official repository is ([CCExtractor/ccextractor](https://github.com/CCExtractor/ccextractor)) and master being the most stable branch.
+
+### **Features**
+
+- Extract subtitles in real-time
+- Translate subtitles
+- Extract closed captions from DVDs
+- Convert closed captions to subtitles
+
+### Programming Languages & Technologies
+
+The core functionality is written in C. Other languages used include C++ and Python.
+
+## Google Code-in 2017
+
+CCExtractor is [participating in Google Code-in 2017!](https://ccextractor.org/public:codein:welcome_2017) 
+
+Google Code-In is a competition of encouraging young people to learn more about Open Source and contributing to it. Tasks range from coding, documentation, quality assurance, user interface, outreach and research.
+
+This is our second year of challenging tasks for pre-university students aged 13-17.
+
+If you are a student fitting the age criteria, interested to contribute to CCExtractor feel free to join us. You can read more at the [Google Code-in website](https://codein.withgoogle.com).
+
+If you're interested in design tasks, you should read [this](https://www.ccextractor.org/public:codein:google_code-in_2017_code-in_for_designers) first. 
+
+## Installation and Usage
+
+Downloads for precompiled binaries and source code can be found [on our website](https://www.ccextractor.org?id=public:general:downloads).
+
+Extracting subtitles is relatively simple. Just run the following command:
+
+`ccextractor <input>`
+
+This will extract the subtitles.
+
+More usage information can be found on our website:
+
+- [Using the command line tool](https://www.ccextractor.org/doku.php?id=public:general:command_line_usage)
+- [Using the Windows GUI](https://www.ccextractor.org/doku.php?id=public:general:win_gui_usage)
+
+You can also find the list of parameters and their brief description by running `ccextractor` without any arguments.
+
+## Compiling CCExtractor
+
+To learn more about how to compile and build CCExtractor for your platform check the [compilation guide](https://github.com/CCExtractor/ccextractor/blob/master/docs/COMPILATION.MD).
+
+## Support

+- CCExtractor can be used as library if compiled using cmake
+- By default the Windows version adds BOM to generated UTF files (this is
+  because it's needed to open the files correctly) while all other

+  You can use -bom and -nobom to change the behaviour.
+
+0.74 (2014-09-24)
+-----------------
+- Fixed issue with -o1 -o2 and -12 parameters (where it would write output only in the o2 file)

+- No more bin output when sending to server + possibility to send TT to server for processing
+- Windows: Added the Microsoft redistributable MSVCR120.DLL to both the installation package and the application zip.

+This is the main documentation of Python extension module for CCExtractor:
+
+====
+CCExtractor Library
+
+----
+Refactoring the codebase into a library
+Earlier version of CCExtractor was compiled as a binary and could not be used as a library. The entire codebase was executed via a single main function defined in ccextractor.c and this architecture was not suitable for extending ccextractor source code to a library. Hence, many modifications were made to ccextractor.c so that conversion to a library could be done. Major modifications were:
+Segmenting the larger functions into smaller functions so that they could be called from one main function. Earlier the entire processing was carried out from one main function itself. This was not a good idea considering the possibility for library. This would allow the user to set the parameters to be passed to CCExtractor from Python with one parameter at a time and not the entire list of all parameters together.
+The refactoring of the code base and architectural judgements as to how the code should be segmented so that the entire working remains the same and also the library structure could be established.
+Apart from these changes, the header file ccextractor.h was also included into the codebase to define many global variables as well as the function declarations of definitions made in ccextractor.c. The major changes could be seen at this PR (merged). However, following the next stages of development after the changes made in the above mentioned PR, the final structure could be found at ccextractor.c and ccextractor.h.
+
+----
+Definitions made in ccextractor.h
+In ccextractor.h, the major changes included declaring global variables which would be accessible throughout the codebase for calling the respective callbacks (discussed later in the documentation) from C to Python for processing the caption frames in Python as they are extracted in CCExtractor. The global variable was also used to keep a track of the start time and end time of caption frames so that the CE-608 grids belonging to the same frame could be clubbed together. The global variable array has been defined and the respective structure definition has also been done in ccextractor.h.
+The global variable array is an instance of this structure. The elements of the structure are PyObject* reporter, int sub_count and struct python_subs_modified* subs. The subs has been defined with start_time and end_time as its elements. More detailed description about why start_time and end_time have been used is given in the section describing about extractors. The main motivation for defining a global variable to catch hold of start time and end time of the caption frames as they are processed in CCExtractor is to identify the text, font and color grids (for CE-608 captions) that belong to the same caption frame.
+The major point to note is that the compilation of Python extension module includes setting a macro PYTHONAPI  which acts as an indication that the compilation is made for Python extension module and this helps in declaring as well as defining the functions which are only needed for Python extension module. As defined here, the PYTHONAPI macro is used to define the functions/variables which are needed only by the extension module.
+Another major advantage of defining the macro PYTHONAPI is that the definitions made for Python extension module only need python-dev package as a prerequisite for compilation. However, if the user wants to compile only CCExtractor and not the Python extension module, then the code should not have python-dev package as a dependency. This has been attained by using macro PYTHONAPI and C pre-processors.
+
+====
+CCExtractor Python Extension Module
+
+----
+Extension module dependencies
+
+1. SWIG
+For generation of the wrappers of the C code base, which would then be used to compile the extension module, I have used SWIG (swig-3.0.12). The entire compilation has been included in a build script (discussed later) and the user need not have prior knowledge of SWIG to get started.
+For compiling the Python extension module, the second dependency in addition to the dependencies of CCExtractor is SWIG. The user can follow these installation steps for getting SWIG installed.
+For generating the wrappers of the C/C++ code in a user required language, the user needs to have a basic understanding of the interface file which is used by SWIG. However, in case of generating the extension module for CCExtractor, the interface file has been written and is available here. SWIG uses this interface file to generate the wrappers for CCExtractor which are then compiled to form the extension module.
+2. Python-dev package
+
+----
+Overall architecture
+
+The entire Python Extension module related work is done in the api/ directory with modifications to the CCExtractor codebase to integrate the divergent path, CCExtractor would take if the processing is done via Python module.
+
+----
+Generating the Python extension module:
+
+For this project, I have mainly used two build scripts, viz., build_api and build_library which are both present in the api/ directory. For generating the Python bindings, user need to just run the build_library script as ./build_library. This would internally generate the SWIG wrappers from the SWIG interface file (ccextractor.i) present in the same directory. The user should note that if the user has not installed SWIG, the the compilation would stop at this step itself. Once the wrappers are generated, then the build_library script  would execute the build_api script which would compile the entire code base of CCExtractor along with the wrappers generated by SWIG. In addition to this, build_api would also compile the extractors and wrappers defined in the extractors/ and wrappers/ directories respectively. Once the compilation is successful, then build_library would generate a shared library called _ccextractor.so from the entire code which would be shared object for the module.
+In addition to generating the  wrapper codes generated by SWIG, it also outputs the ccextractor.py which would be later used as Python extension module for accessing CCExtractor functionality via Python.
+As mentioned in earlier section, the build_api compiles the entire code base with an option -DPYTHONAPI which is used by GCC to define a macro PYTHONAPI. This macro then acts as a signal telling that the extension module is being generated and the bindings dependency need a check as well as the bindings dependent functions need to be defined.
+
+----
+Workflow of Python extension module
+
+The following section encompasses on the detailed description of the entire workflow of Python extension modules and the importance of each function in the codeflow. An example usage has been done in api_testing.py.
+
+****
+api_init_options
+Function declaration- struct ccx_s_options* api_init_options()
+This function returns an initialized instance of struct ccx_s_options which is modified in CCExtractor according to the values of the parameters provided by the user while executing CCExtractor.
+****
+check_configuration_file
+Function declaration- void check_configuration_file(struct ccx_s_options api_options)
+This function is used to check the configuration file and it takes the struct ccx_s_options instance as returned by api_init_options().
+****
+api_add_param
+Function declaration- void api_add_param(struct ccx_s_options* api_options,char* arg)
+The api_add_param function is used to add user passed parameters to the struct ccx_s_options instance which would be used to compile the parameters and make the necessary modifications in the working of CCExtractor.
+This function takes the instance of struct ccx_s_options passed to check_configuration_file function and also, the string denoting the parameter passed by the user.
+The parameters are added to the python_params element of struct ccx_s_options and the count of the parameters is kept in python_param_count.
+****
+my_pythonapi
+Function declaration- (depends on whether the compilation is done as CCExtractor binary or as                             extension modules)
+The my_pythonapi is defined on the basis of how the compilation has been done by the user. If the user wants to use CCExtractor binary rather than the Python extension module, then this function is defined as #define my_pythonapi(args, func) set_pythonapi(args)  with the set_pythonapi being defined in wrapper.c.
+However, if the user wants to build the extension module, then the definition of my_pythonapi is done as #define my_pythonapi(args, func) set_pythonapi_via_python(args, func) with the set_pythonapi_via_python function being defined in wrapper.c.
+Thus, it can been observed that my_pythonapi takes two arguments when the compilation is done as extension module. In both the case, the first argument is struct ccx_s_options instance as used by api_add_param. But in case of compiling the extension module, the my_pythonapi function takes a second parameter which is the python callback function that CCExtractor would call when passing values from C to Python (a detailed discussion about this has been done later).
+This function is not a mandatory function to call when using the CCExtractor binary.
+****
+compile_params
+Function declaration- int compile_params(struct ccx_s_options *api_options,int argc)
+The compile_params function mainly compiles all the parameters supplied by the user and modifies the elements of the api_options on the basis of the parameters supplied by the user.
+In this function, we add a dummy parameter ./ccextractor so that the parse_params function which is called from compile_params function properly compiles all the parameter except the first parameter as done in here.
+This function then returns the return value as obtained by the parse_params function.
+****
+call_from_python_api
+Function declaration- void call_from_python_api(struct ccx_s_options *api_options)
+The call_from_python_api function checks if the parameter -pythonapi was provided by the user. If the parameter was passed by the user then the global varable signal_python_api is set to 1 showing that the execution is done via Python modules; otherwise the value of signal_python_api is 0.
+In case of clarifications, the user does not explicitly need to pass the parameter -pythonapi. It is passed by the my_pythonapi function and thus used by call_from_python_api to set the signal_python_api to 1.
+****
+api_start
+Function declaration- int api_start(struct ccx_s_options api_options)
+This is the most important function of entire processing done by CCExtractor. After the entire compiling of parameters have been completed, then comes the stage when the actual processing is done.
+The api_start is the function which is majorly responsible for extracting the caption frames and passing them back to Python for processing.
+
+The user should note that the codeflow discussed above till this point is generic to both CCExtractor binary as well as CCExtractor’s Python extension module. From this point onwards, the codeflow that has been described is mainly how the Python extension module accepts the caption frames via callback function and then processings done on the caption frames to generate the output subtitle file (.srt) via Python.
+
+The api_start function in case of CE-608 captions calls a function general_loop for processing of the sample(video) that needs to be processed which in turn makes a call to encode_sub which encodes the subtitle buffer obtained from the sample.
+In encode_sub function, the sub_type is checked to be CE-608. If the sub_type is 608, then another check is made to check the value of signal_python_api. If the signal_python_api is set to 1, then a call to pass_cc_buffer_to_python is made. Otherwise, the processing continues as if the call for processing was made from CCExtractor binary.
+From the pass_cc_buffer_to_python function, the call is made to the extractor function, then the extractor function in turns calls the callback function provided earlier via my_pythonapi function. The arguments given to the callback function are the ones corresponding to the information content of the caption frame which has been processed by CCExtractor. This information is accessed via the Python SRT generator scripts which would process the caption frames and write the processed information in the output subtitle files.
+The following sections would be sequential in-detail descriptions about how each process functions:
+
+----
+Python Encoder for CCExtractor
+
+Following the architecture of CCExtractor’s codebase, a new file named ccx_encoders_python.c was added. The main reason of adding this file was to define the functions which would be called when the extraction process or CCExtractor extraction functionality is being performed via Python extension module. At this moment, since the extension module extends support only for CE-608 samples, only pass_cc_buffer_to_python function has been defined. Later on, when the binding’s support is extended to support other formats then in  that case other functions like pass_cc_bitmap_to_python and others would be included in this file following the architecture of other encoders.
+****
+pass_cc_buffer_to_python
+Function declaration- int pass_cc_buffer_to_python(struct eia608_screen *data, struct encoder_ctx *context)
+This is the function where the actual work of passing the extracted caption buffer to Python extension modules for processing the caption frames is done.
+The pass_cc_buffer_to_python function is called when the sample from which the caption frames are to be extracted is a CE-608 sample and the call for extraction is made from Python extension module.
+In this function, whenever a caption frame element is extracted, be it the srt_counter, caption timing information or any information related to the text, font or color grid of the CE-608 captions, then that information is passed to extractor function defined in extractors/ directory. A detailed description about how exactly the extractors function would be included in the next section.
+
+----
+Extractors for bindings
+
+As documented in the previous section, when the extraction of CE-608 caption frames in done via Python, then the call is made to pass_cc_buffer_to_python function defined in ccx_encoders_python.c. In this function, after extracting lines in a caption frame (lines may belong to any of the text, font or color grid for CE-608), those lines are passed to python_extract_g608_grid function defined in extractors.c.
+****
+python_extract_g608_grid
+Function declaration- void python_extract_g608_grid(unsigned h1, unsigned m1, unsigned s1, unsigned ms1, unsigned h2, unsigned m2, unsigned s2, unsigned ms2, char* buffer, int identifier, int srt_counter, int encoding)
+The main aim of using python_extract_g608_grid function is to able to identify the lines belonging to a particular frame and then passing these lines to the Python callback function with added identifiers for identification as to which CE-608 grid those lines belong to in a particular caption frame. More documentation about the identifiers and the nomenclature used for the bindings has been documented in the ‘Support for only CE-608 captions’ section and the user is advised to read that section to get a better understanding of the nomenclature.
+The arguments passed to python_extract_g608_grid  include encoding which is the encoding that CCExtractor would have used to write the output subtitle file. Thus, the encoding is passed from CCExtractor to Python via the callback function so that the output subtitle file generated by Python would have the same encoding as the output generated by CCExtractor would have had.
+Out of all the arguments that are passed to the python_extract_g608_grid function, the one interesting argument is the identifier argument which has different values depending on the type of caption frame line it is called with. For example, if the line passed to python_extract_g608_grid function is a line belonging to its color grid, then the value of the identifier would be 2. Similarly, we have:
+identifier = 0 -> adding start and end time
+identifier = 1 -> subtitle
+identifier = 2 -> color
+identifier = 3 -> font
+This is how the python_extract_g608_grid function is able to generate the entire caption frame for a CE-608 sample along with timings.
+
+----
+Callback Function architecture
+
+When using the extension module, when a particular C function is called from Python, the control is transferred to C and returned to Python only after the execution of the function. However, according to the adopted architecture, a single function would process the entire sample and extract all the caption frames until the control is passed back to Python for processing the captions in Python. Thereupon, for further processing in Python the user would have had to wait until the end of the extraction of all the caption frames from the sample. This would violate the basic ideology that the module should be able to process the caption frames in Python as they are extracted in CCExtractor rather than waiting till the end of extraction from the entire sample.
+As a result of this, the callback function architecture was adopted. The main advantage of this architecture is that the moment a line from the caption frame is extracted the line is passed via a callback function to Python and the processing of the extracted line could be done in Python.
+In the present architecture, the user has a flexibility to tell CCExtractor which Python function would act as a callback function and a mechanism has been designed to convey this function to CCExtractor. This has been done with the use of my_pythonapi function as discussed in the previous sections.
+NOTE: In the api_testing.py, I have defined the callback function to be named callback. However, the user has complete freedom to define any name for the callback function. The user needs to note that the callback function would be getting nothing but a line from the caption frame that is extracted by CCExtractor. Further processing of the extracted line is the responsibility of the user.
+After defining the callback function, the user needs to make sure that this function is passed via Python to CCExtractor so that it can be used for callback. For doing so, the user needs to set the second argument of the function my_pythonapi as the callback function. This has been done in the api_testing.py script and the user can refer to it for example.
+A detailed description about why a single line of the caption frame is passed via the callback function and not the entire frame is described in detail in later sections.
+Also, when the user passes the callback function via Python to CCExtractor so the my_pythonapi function saves a pointer to this function as an element to a global structure, array, defined and declared in ccextractor.h. The element reporter holds the callback function passed by user via Python.
+Whenever the user wants to pass a line to the callback function then the user needs to call the function run which has been defined in ccextractor.c.
+****
+run
+Function declaration- void run(PyObject * reporter, char * line, int encoding)
+The run function takes two arguments and their description is as follows:
+The first argument is the callback function which the user passes via Python. According to present architecture, this callback function is contained by the element reporter contained in the global structure named array. So the first argument is array.reporter.
+The second argument to the run function is the line which needs to be passed to Python.
+This is how the callback mechanism works for passing the lines from C to Python in real time.
+
+----
+Processing output in Python
+
+As described in the previous sections, the extension modules just return a single line from the caption frames. The processing of the caption frames to generate the output subtitle file is done in Python.
+A script to generate an output subtitle file from the extracted captions frames in Python has been written. The api_testing.py has a function named callback which acts as a callback function returning the extracted caption lines in Python. These lines then are passed to generated_output_srt in api_support.py described in the api/ directory. Thereupon, the function searches if the line has specific identifier which are used to decide how the output would be generated. A detailed section has been included in this documentation regarding the nomenclature used for processing different lines in CE-608 format caption fields (Support for only CE-608 captions section). The main reason for doing so is to avoid any buffering in C to hold the caption lines until the entire caption frames are extracted. This facilitates real time processing of the extracted caption frames.
+For getting the output filename from CCExtractor which would then be used to write the output srt file from Python, whenever the code is run from the extension module the first line that is passed via the callback function is the output filename generated by CCExtractor. This is incorporated by calling the callback function from init_write function defined in the src/lib_ccx/output.c file. The line passed to the callback function is of the format filename-<name of the output file to be generated> and this is then used to generate the output file. This line is then captured in the generate_output_srt function defined in the api_support.py.
+However, if the user wants the flexibility of defining the filename in a different manner, then for such outputs, the user must make changes in the generate_output_srt function to set the filename and ignoring the first line that appears in Python via the callback function.
+
+----
+Support for only CE-608 captions:
+
+For understanding the CE-608 caption format, the user is advised to refer to this documentation on CE-608.
+
+The Python extension module is so far able to extract the captions frames from CE-608 samples. In samples with CE-608, the caption frames that are extracted by CCExtractor are in the form a 15x32 grid which depicts the screen. Thus, the information regarding the font of the captions, the colour they would be having on the screen as well as their alignment on the screen is captured in font,color and text grids respectively.
+Using Python modules each of such grids can be accessed in Python. However, as described in the previous section the callback function gets a single line and not the entire grid from CCExtractor, some processing needs to be done in Python for getting the user required grids per caption frames.
+The functions which would be acting as the processing and buffering functions for grid generations are present in the ccx_to_python_g608.py. The two major functions are return_g608_grid and g608_grid_former. The g608_grid_former is mainly used to form the grid from lines obtained at the callback function.
+The main advantage of the return_g608_grid function is that the user can generate whatever pattern the user desires to process in Python. For accessing various different combinations of the font, color and text grids in CE-608, a help_string has been defined in the return_g608_grid function in the ccx_to_python_g608.py file which describes on the value of mode to be passed to this function to get proper combination of the grids.
+In the earlier sections it has been stated that the callback function in Python is not passed with the entire caption frame but just one single line from the frame, a particular nomenclature has been devised to make sure that the lines belonging to the same caption frames are identified in the Python interface. The nomenclature is as follows:
+For every frame, the first line that is passed to the callback function is the srt_counter which indicates the identifier value of the caption frame that would be extracted next.
+Following the srt_counter, the next line would contain a conjunction of the start time and end time of the caption frame with respect to the timings when the captions would be visible on the screen. The start_time and end_time would be conjuncted as start_time-<start time>\t end_time-<end time>\n and the user needs to process this line to get the timings. This processing in case of getting a srt file as an output has been done in the generate_output_srt function.
+After the timings have been sent via the callback function, until the next srt_counter is extracted, the lines containing information about the color, font or text grids of CE-608 samples are passed via the callback  function to Python.
+For processing the grids separately, the color grid could be identified by identifying the presence of color[<srt_counter value>]:<color grid line> in the line obtained from the callback function. Similarly, for the font and text grids, the nomenclatures are font[<srt_counter value>]:<font grid line> and text[<srt_counter value>]:<text grid line> respectively. Processing a grid on the basis of such a nomenclature has been done in the g608_grid_former in the ccx_to_python_g608.py file.
+After the entire caption frame has been sent via the callback function to Python for further processing, when the extraction of present caption frames finishes and CCExtractor shifts to a new frame, then a line containing ***END OF FRAME*** is passed via the callback function from C to Python. The user needs to catch this line in order to get the signal that from the next line onwards a new caption frame would begin. Similar approach has been implemented in the function generate_output_srt in the api_support.py file.
+This is how the entire CE-608 is transmitted to Python and the user needs to follow the nomenclature in order to get the caption frames in Python.
+However, if the user thinks to modify the nomenclature in accordance with some other nomenclature that suits their use case, then the user can do so by editing the python_extract_g608_grid function in the extractor.c file. In this file, the user needs to find the lines where the function run is called with its first parameter being the callback function that is passed from Python and the second parameter being the line which is to be passed to Python.
+
+----
+Wrappers for the extension module
+
+In case of using an API, it is highly desired to set the parameters desired by the user not via command line but as call to built-in functions. This gave rise to the necessity of wrapper functions which can be called to set certain parameters for directing the functioning of the bindings.
+The wrappers have been defined in the wrapper.c file in api/wrappers/ directory. The user can use just call the wrappers to set some parameters. More wrappers can be defined according to the architecture followed in wrapper.c.
+The user needs to note that the wrappers can be called anytime in between adding parameters to CCExtractor instance (as done in api_testing.py) and before calling the compile_params function from the CCExtractor module.
+Another thing to note about the wrapper is that, the my_pythonapi wrapper function is a very important wrapper function. It tells CCExtractor that the call has been made using the Python module and thus the functioning of CCExtractor is altered. Hence, if the user intends to use the Python module the user is always advised to call this wrapper function with its first argument to be the object returned by api_init function from CCExtractor module and second argument being the callback function which would be called by the CCExtractor to pass the extracted caption lines back to Python.
+
+----
+Test Script
+
+Once the Python module are generated then the user can use them by importing ccextractor module in Python.
+For testing the output of the bindings a test script, api_testing.py. But to mention, the module at this stage only supports generating a subtitle file from the CE-608 standard samples only.
+Another testing feature, that has been added is that the user can use recursive_tester.py to generate the subtitle files for all the samples from a directory. The only parameter needed to run this script is the location of all the samples.
+
+----
+Silent API
+
+The Python bindings have been designed in such a way that the API is silent in itself as well as in the form of output generation. Silent in itself means that the API doesn’t write out any output to the STDOUT and the entire output of CCExtractor is silenced when the module is used for extraction of caption frames. This feature has been made possible by passing a parameter -pythonapi internally in api_testing.py using the function my_pythonapi() from the ccextractor module. The -pythonapi internally makes CCExtractor to silence all the outputs that could have been generated otherwise.
+If the user wants to add some print functionality from the CCExtractor, then may be defining the prints using printf C function could be an option. Note that the user cannot use the mprint function to get prints from the extension module from inside the CCExtractor C code part as used in CCExtractor to get the desired STDOUT prints as these are silenced via -pythonapi.
+
+====
+Work status
+The proposal made by me for this project had a major component of multi-threading to let CCExtractor’s Python bindings run the CCExtractor’s extraction process in multi-threads.
+However, the end goal was modified while the GSOC 2017 coding period and after Second Phase Evaluation, the main aim was to create a Python extension module for CCExtractor which could process CE-608 video samples, extract the caption information present in them and pass this information to Python for further processing. The module was expected to be silent and the output generation from the caption information present in the video sample has to be done via Python.
+The present status of the extension module is that the module can extract caption information from CE-608 standard video samples and pass the caption information to Python. Further work has also been done to process this caption information to generate an output subtitle(srt) file (the user is advised to check completion of comparing_text_font_grids function sub-section under the future work section).
+
+====
+Future Work
+
+----
+Identifying the input format and raising errors if unsupported
+
+CCExtractor does not process any non-video files. Similarly, the processing of non-video files is not supported by extension module. However, since the API has been designed to be silent, the module doesn’t output any error log stating that the input file is a non-video file and it cannot be processed.
+This is a much desired feature and the present version of CCExtractor extension module lacks this feature. I would be working on this feature post GSOC 2017 but if any user finds that this feature has not been added until they start contribution to CCExtractor’s extension module, then their work on this feature would be highly appreciated.
+For adding this feature to extension module, the extension module must be extended to process the return value from CCExtractor as done in the api_start function. When the sample (non-video) is processed via CCExtractor’s binary, then the processing is stopped by raising an ‘Invalid option to CCExtractor Library’ error. However, since the extension module has been designed to be silent, this error message is suppressed. Hence, the user should extend the test scripts to process the return value of api_start function in python extension module according to the constants defined in ccx_common_common.h
+
+----
+Callback class mechanism
+
+The present architecture uses a callback mechanism to pass the extracted caption lines from the caption frames of CE-608 captions to Python for further processing. In the callback mechanism, a callback function is supplied to CCExtractor in C via the my_pythonapi function which stores the callback function as a PyObject* in the global variable array. However, according to Python documentation on C-API, everything in Python is a PyObject; be it a function, a tuple or a class.
+So, the ideology is to replace the present callback function by a class which can have many methods that the user can use for different use cases.
+An example of such an implementation has been done here. The user needs to note that for accessing the Python class in C, some modifications need to be done to the run function defined in ccextractor.c and a sample example for calling a class method named ‘callback’ could be found here.
+Also, an important point to be noted in this case is that the user needs to pass the callback function’s name to run function in C so that the corresponding callback method of the class passed via my_pythonapi could be called via C. As an example, the callback method’s name has been provided here.
+For understanding the exact implementation of this approach, I would recommend the user to understand C-API for Python as the documentation is quite extensive to every use case.
+
+----
+Completion of comparing_text_font_grids function
+
+The Python extension module for CCExtractor is able to pass lines of the caption frames for different grids of CE-608 captions. However, for generating the subtitle file from the caption grids, the text grid needs to be modified according to the color grid as well as font grid. In CCExtractor, this job is done at the function, get_decoder_line_encoded.
+For generation of subtitle files (.srt files) from Python, an equivalent version of get_decoder_line_encoded has been implemented in Python and has been defined as comparing_text_font_grids in python_srt_generator.py
+However, as the user can note that this function is not a complete implementation of get_decoder_line_encoded function, completion of this function’s definition is a matter of future work.
+
+----
+Adding more wrapper functions
+
+As described in the ‘Wrappers for the extension module’ section, more wrapper functions are needed to be declared in the wrapper.c file. For example, few wrappers have been defined. More wrapper functions can be defined in a similar manner.
+Extending the module to support other caption formats
+In this version, CCExtractor’s extension module supports processing of video samples having CE-608 standard captions in them and writing these captions to output subtitle (.srt) files.
+However, CCExtractor in itself has support for other caption standards like DVB, 708 etc. So, extension of module to extract of caption information from samples containing the caption information in these formats is a future task.
+The user should note that the information passed from CE-608 to Python is in raw form as lines which are then used to form the 608 grids. Similarly, the extension to other formats must consider passing the raw information of caption in respective format and then processing the information extracted by CCExtractor in Python.
+While extending, the architecture to be followed for ccx_encoders_python should be consistent to other encoders in the codebase to maintain uniformity. Thus for DVB samples, a function name pass_cc_bitmap_to_python and for 708 samples pass_cc_subtitle_to_python need to be declared in ccx_encoders_python.c.
+
+====
+PyPI module
+(This section is for contributors who want to upload the package to PyPI)
+The PyPI module that has been uploaded has many things added to the CCExtractor code tree and all of this can be found here (branch - manifest_file).
+The contributor is advised to use the documentation at ‘An Introduction to Distutils’ and its subsequent parts to understand this section.
+The overall strategy or steps that have been followed to generate the distribution for being uploaded to PyPI is as follows:
+
+----
+Adding files to distribution and generating the distribution
+
+All the files that are needed to be included in the package distribution are to be added the MANIFEST file as done here. For understanding the syntax used in MANIFEST file the user can check this documentation.
+After the MANIFEST file has been written properly, the user can generate the distribution package by the command
+python setup.py sdist
+This command would generate the distribution on the basis of MANIFEST file and place in the dist/ directory as a .tar.gz file until specified otherwise by the user.
+One thing to mention about the MANIFEST file is that it can only include files/folders from the folder it is defined within. It cannot include directories/files from parent directory or any other child directory. However, in the MANIFEST file I used, I have added the symlink to src main src directory so that the source code can be added to the package distribution via the MANIFEST file.
+
+----
+An analysis of the setup.py file used
+
+The setup.py has been used to install the Python module on the user system. To understand what all the parameters mean in setup the user must refer to this documentation.
+The cmdclass defined at line is a very important part of the script as it internally makes call to the scripts included in package_build_scripts. A point to note is that this directory is used to include the scripts into the package distribution via the MANIFEST file.
+The scripts in package_build_scripts are the scripts which do the actual compilation of the source code to required python module and shared object. The user is advised to refer to build_library_package and build_api_package to understand how to compilation process takes place. The user may also refer to this documentation for understanding how the build scripts work.
+For any modifications made to the build scripts, viz, build_library and build_api corresponding modifications are to be made to the scripts included in package_build_scripts so that the compilation does not fail while installing the Python extension module.
+The ccextractor.i used in the package_build_scripts is an interface file used by SWIG to generate the wrapper codes. This is an essential part and should always be present with the distribution.

+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the

+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.

+
+    This program is free software; you can redistribute it and/or modify

+
+```bash

+For building CCExtractor using cmake follow steps below..
+
+Step 1) Check you have right version of cmake installed. ( version >= 3.0.2 )
+	We are using CMP0037 policy of cmake which was introduced in 3.0.0
+	since we have tested our system only with cmake version 3.0.2, I would
+	suggest to use 3.0.2 or higher version.
+
+
+Step 2) create a separate directory where you want to build the target.
+	In Unix you can do it using following commands.
+	~> cd ccextractor
+	~> mkdir build
+
+Step 3) make the build system using cmake
+	~> cmake ../src/
+
+Step 4) Compile the code.
+	~> make
+	~> make install
+
+Step 5) Use CCextractor as you would like
+
+
+If you want to build CCExtractor with FFMpeg you need to pass
+cmake -DWITH_FFMPEG=ON ../src/
+
+If you want to build CCExtractor with OCR you need to pass
+cmake -DWITH_OCR=ON ../src/
+
+If you want to build CCExtractor with Sharing and Translating service:
+cmake -DWITH_SHARING ../src/
+
+Hint for looking all the things you want to set from outside
+cmake -LAH ../src/

-Note: I don't currently have a Mac to test Mac builds. An effort is done to ensure that CCExtractor is portable,
-which is why it compiles and works in Mac without any effort. But the build script (any of its 2 lines) is not
-maintained. If it doesn't compile for this version please fix and send me the new file so I can add it to the
-official version.
