* Add update_gpac.py
Add a Python script that partially automates updating GPAC to a newer
version.
* Update GPAC to version 1.0.1
Update the vendored version of GPAC to version 1.0.1.
* Add necessary GPAC header files
Add some GPAC header files that GPAC needs to compile.
* Define _GF_CONFIG_H_ to fix Linux build failing
gpac/configuration.h has a series of default configuration options for
various platforms, but it doesn't have a case for Linux and it results
in a compilation error if it encounters an unknown platform.
The settings in configuration.h don't appear to try to set any defaults
for Linux anyway, so we can disable all use of those configuration.h
settings by defining _GF_CONFIG_H_.
* Add some more necessary GPAC header files
Add a few more header files necessary to get GPAC to compile.
* Fix renamed and removed media types
Some mp4 media types ("clcp", "c608") were renamed by GPAC. "c708"
appears to have been removed, so we can just add the definition of that
to the top of mp4.c.
* Remove Remotery from updated GPAC
Remotery appears to be some code for profiling GPAC which we aren't
using, and including Remotery.c and Remotery.h ends up pulling in a lot
of files, so it's easier to just remove the include of Remotery.h and
the single use of it in os_divers.c
* Remove unused box definitions
Remove box definitions that we don't use from box_funcs.c in order to
avoid adding too many files from GPAC.
* Replace alloc function declarations with defines
Replace the GPAC wrappers around the malloc-style functions (gf_malloc,
gf_free, etc.) with defines that use the standard C versions of these
functions so that we can avoid including GPAC's alloc.c
* Remove WebVTT handling code in gf_isom_dump_srt_track
Remove the code that handles WebVTT in gf_isom_dump_srt_track to avoid
needing to pull in a lot of other files from GPAC.
gf_isom_dump_srt_track doesn't appear to be used by ccextractor directly
or indirectly (it's only called in gf_isom_text_dump which doesn't
appear to be called anywhere else) so it should be fine removing it.
* Disable use of Remotery and gzip on Linux
Use GPAC_DISABLE_REMOTERY and NO_GZIP to disable Remotery because we
aren't interested in profiling (see
5c0c9cf71e for more info) and gzip
compression through gzio.c respectively.
* Fix compilation errors in GPAC on linux
GPAC on linux after the update requires some threading functions and
dynamic loading functions in pthread and dl respectively.
* Add necessary files for GPAC to compile
Add several C and header files that GPAC needs to compile
* Disable Remotery and Gzip in all build systems
Disable Remotery and gzip (using the same method as
f49dc371b5) for:
- The linux build script (linux/build)
- The mac build script (mac/build.command)
- The mac makefile
- cmake
- bazel
- Visual Studio
* Add extra GPAC files to several build systems
Add the names of several GPAC files that were added in the update to the
linux and mac Makefiles and to the Windows Visual Studio project.
Adding these filenames isn't necessary for CMake, Bazel, or the linux or
mac build scripts because all of them compile all C files recursively in
the src/thirdparty/gpacmp4 directory instead of having an explicit list
of files to compile.
* Change NO_GZIP to GPAC_DISABLE_ZLIB in VS project
Instead of defining NO_GZIP to disable gzip support, define
GPAC_DISABLE_ZLIB, which does the same thing but also prevents the
compiler from trying to zlib.
* Avoid using GPAC's configuration.h completely
GPAC's configuration.h has a few problems with the defaults that it
sets:
- It defines GPAC_MEMORY_TRACKING on Windows, which switches to an
alternate implementation of malloc, meaning that we would have to pull
in alloc.c
- It causes compilation errors on Linux (see 9164c08979)
This disables using configuration.h by:
- Defining GPAC_HAVE_CONFIG_H to make GPAC use a separate config.h file
instead of the default configuration.h file
- Making an essentially empty config.h file to make attempts to include
it not fail
This commit also removes configuration.h from the repo to make sure we
don't accidentally include it, and removes the _GF_CONFIG_H_ hack from
the previously mentioned commit because we don't need it anymore (it's
sole purpose was avoiding using configuration.h).
* Link pthread and dl on Mac and Linux
Add -lpthread and -ldl to link pthread and dl respectively on Mac and
Linux. Needed because the update to GPAC 1.0.1 introduced os_thread.c
(which uses pthread) and os_module.c (which uses dlsym and related
functions).
* Remove unused Remotery.h header file
5c0c9cf71e removed the only use of
Remotery.h in the GPAC files that we pulled in, so there's no need to
keep it around.
* Add GPAC update to changelog
* Fix cmake build error
Building with CMake currently fails because it can't find functions from
dl (dlopen, dlsym, etc.)
* Fix bazel build error
Bazel currently doesn't find the header files in gpac/modules/ when
building gpac, most likely because it isn't searching all directories in
gpac/ recursively for header files
* Define GPAC_HAVE_CONFIG_H in lib_ccx BUILD file
lib_ccx indirectly includes gpac/tools.h, which tries to include
gpac/configuration.h, which was removed in
b46c4e8a2d. This just copies the solution
from that commit to the bazel BUILD file (defining GPAC_HAVE_CONFIG_H so
GPAC uses gpac/config.h instead).
* Link to dl and pthread in bazel GPAC BUILD file
The updated GPAC version requires functions from dl and pthread, which
weren't linked to previously when building with bazel.
* cea708: Fix missing new line in log message

* build: Disable pointer-sign warning

An if statement before the call to g608_extractor has also been added.
Waiting for Carlos to comment on the output generated till this stage.
* added a signal_python_api check before calling every write function.
Thus basic writing output can be avoided.
* Commented all calls to python_extract_time_based.
making changes to python_extract_g608 to be called only from the point
when a g608 caption is detected.
* Added pass_cc_buffer_to_python in encoders_common.c temporarily
redefined get_*_encoded from static to normal
included the above functions in encoders_common.h
* Added if-else statement for switch in encode_sub function.
This is done mainly for making sure no output is generated in the api
call.
* Added ccx_encoders_python.c
Defined pass_cc_buffer_to_python in ccx_encoders_python.c
added if else statement in encode_sub's switch to make sure that the output is not generated in case of -pythonapi call
* Removed __wrap_write from the entire code base.
It's declaration and definition are only present in CCExtractor.*
* Commented out the /dev/null part in ccx_encoders_common.c.
Proceeding further on checking for file generation.
* Added output_filename in array global variable and is generated in
init_write function.
included ccextractor.h in output.c to access global variable
signal_python_api for avoiding output generation in init_write and
invalid free in dinit_write.
* Modified the definition of init_write function for accessing
signal_python_api.
* Deleted the commented part of /dev/null in ccx_encoders_common.c.
* Added target_message=0 in -pythonapi param parsing in param.c to avoid
the API from printing to STDOUT.
Deleted the commented part of -out=pythonapi.
Thinking of adding a different param for silencing the output when the
call is made from python api.
* Removed __wrap_write from ccextractor.c and ccextractor.h.
* Added ccx_to_python_g608 and modified api_support.py file.
added documentation in ccextractor.c.
* added the generate srt script. However, some random characters are
coming in first line. Need to talk about this.
* Added SRT generator for python.
Using string to remove the garbage value.
Add code for srt counter and also the start_time and end_time
conversion.
* removed the trash characters and added code to print the timings.
However, the last blank frame also results in a print. Need to take care
of this.
* rectified the mistake of writing only timings and not captions.
now next step is to just make the timings print properly
* some minor changes before diving into extracting srt_counter from the made codebase
* Added extraction of srt_counter in python_extract via fflush
srt_counter-value.
Need to modify the processing in python.
* Added the entire method to extract captions and generate srt files. Next, step would be a to define a concise function for writing the srt
* Processing into a srt working properly.
Next step is to add the information of font into the caption text.
* the data is getting generated for proper SRT counters.
* A turning point to the appraoch.
Added END OF FRAME line for printing the data for every particular
srt_counter.
Proceeding further with the generation of srt by data manipulation.
* some minor bugs but the output srt is being generated correctly. However, The font and colour encoding needs to be done.
* Taken care of random characters. Need to discuss this with Carlos. Moving further to font/color processing.
* Taken care of random characters. Need to discuss this with Carlos. Moving further to font/color processing.
* Added fflush and cleaned up the python code of srt generation
* Added <i> tag for italics.
Proceeding further with other types.
* Added the code to check for underline.
However, need to check how CCExtractor generates srt when both italics
and underline are present. For now a new line is added if both are
present.
* Shifting for making changes in th i/O work.
* Stable ouput for samples with italics is being generated.
* Added the PYTHONAPI macro definition and testing for its existence in the set_python_api function.
* build script for linux is working correctly.
Build_library is showing error of invalid def of set_pythonapi.
Moreover, extractor has some memory seg fault.
* Added mod to set a MACRO as my_python_api to set the callback function.
Till now all calls to the reporter are commented.
Working on getting the reporter to print the lines.
* Changes have been implemented to bring reporter in working state.
For now a constant string is passed from extractor. Need to make the
proper parsing possible.
* Changed the code in extractor such that entire grid is returned to the
callback function.
Need to provide this grid to the write function and also cleanup the
codebase.
* Writing the outputted srt in a file called "temp.srt".
Need to modify init_write to push filename that is to be created in
python using callback.
* Added code to get start and end time simultaneously.
entire SRT is getting generated.
* removed ccx_python_encoders.c
* Compiling and executing on Windows
* Moved definitions get_line_encoded, get_color_encoded, get_font_encoded from ccx_encoders_g608.c to ccx_encoders_common.c.
Also, deleted the static definition of get_font_encoded from
ccx_encoders_webvtt.c
* added a write statement in write_cc_bitmap_as_srt
* Rectified transfer of get_line_encoded, get_color_encoded and
get_font_encoded from ccx_decoders_common.c to ccx_encoders_common.c.
