GPAC renamed its libraries to `libgpac.so.13` causing image build to fail: ``` Error: building at STEP "COPY --from=builder /usr/local/lib/libgpac.so.12 /usr/local/lib/": checking on sources under "/home/pszemus/.local/share/containers/storage/overlay/faa4f2b5c39251a5cf42a97234d2d5652336a2388c96a64d85fc1922c4c43a71/merged": copier: stat: "/usr/local/lib/libgpac.so.12": no such file or directory ``` so let's fix the gpac version to the latest release (2.4.0)
CCExtractor Docker image
This dockerfile prepares a minimalist Docker image with CCExtractor. It compiles CCExtractor from sources following instructions from the Compilation Guide.
You can install the latest build of this image by running docker pull CCExtractor/ccextractor
Build
You can build the Docker image directly from the Dockerfile provided in docker directory of CCExtractor source
$ git clone https://github.com/CCExtractor/ccextractor.git && cd ccextractor
$ cd docker/
$ docker build -t ccextractor .
Usage
The CCExtractor Docker image can be used in several ways, depending on your needs.
# General usage
$ docker run ccextractor:latest <features>
- Process a local file & use
-oflag
To process a local video file, mount a directory containing the input file inside the container:
# Use `-o` to specifying output file
$ docker run --rm -v $(pwd):$(pwd) -w $(pwd) ccextractor:latest input.mp4 -o output.srt
# Alternatively use `--stdout` feature
$ docker run --rm -v $(pwd):$(pwd) -w $(pwd) ccextractor:latest input.mp4 --stdout > output.srt
Run this command from where your input video file is present, and change input.mp4 & output.srt with the actual name of files.
- Enter an interactive environment
If you need to run CCExtractor with additional options or perform other tasks within the container, you can enter an interactive environment: bash
$ docker run --rm -it --entrypoint='sh' ccextractor:latest
This will start a Bash shell inside the container, allowing you to run CCExtractor commands manually or perform other operations.
Example
I run help command in image built from dockerfile
$ docker build -t ccextractor .
$ docker run --rm ccextractor:latest --help
This will show the --help message of CCExtractor tool
From there you can see all the features and flags which can be used.
