# FFmpeg Packaged for Zig

This is a fork of [ffmpeg](https://ffmpeg.org/), packaged for Zig. Unnecessary
files have been deleted, and the build system has been replaced with
`build.zig`.

There are no system dependencies; the only thing required to build this package
is [Zig](https://ziglang.org/download/).

Zig API bindings are also provided via the "av" module. See `doc/examples` for
API usage examples.

## Differences from Upstream

* Only a single static library is produced. There is no option to create a
  dynamic library.
* The ffmpeg command line tool is not provided. Perhaps this could be added if
  desired.
* Documentation, tests, and tools are not provided.
* This package enables everything supported by the target; it does not expose
  configuration options to choose the set of supported codecs and formats.
* The set of external library integrations is fixed.

## External Libraries Included

* [x] libmp3lame
* [x] libvorbis
* [x] libogg

More can be added as desired.

## Update Process

These are the instructions to update this package when a new FFmpeg version is
released upstream.

1. Merge the new tag into main and resolve all conflicts by replacing the
   conflicting files with the files from upstream.
2. `find libavcodec/ libavdevice/ libavfilter/ libavformat libavutil/ libswscale/ libswresample/ -type f -name "*.asm" -o -name "*.c" -o -name "*.S"`
   * Edit to omit files ending in `_template.c` or `_tablegen.c`
   * Sort the list
   * Update the `all_sources` list in `build.zig`.
3. Inspect the git diff to keep some of the source files commented out like
   they were before. Some handy filtering rules apply:
   * `/L` prefix means Linux-only
   * `/W` prefix means Windows-only
4. Run `./configure --prefix=$HOME/local/ffmpeg --disable-doc --disable-htmlpages --disable-manpages --disable-podpages --disable-txtpages --disable-programs --enable-libmp3lame --enable-libvorbis --disable-shared --enable-static`
   against upstream and diff the generated `config.h` file to the one generated
   by this build script. Apply appropriate changes to `build.zig`.
5. Update these files which are generated by the upstream configure script:
   * `config_components.h`
   * `libavfilter/filter_list.c`
   * `libavcodec/codec_list.c`
   * `libavcodec/parser_list.c`
   * `libavcodec/bsf_list.c`
   * `libavformat/demuxer_list.c`
   * `libavformat/muxer_list.c`
   * `libavdevice/indev_list.c`
   * `libavdevice/outdev_list.c`
   * `libavformat/protocol_list.c`
6. Update the `headers` list in `build.zig` based on what files are present in
   `$HOME/local/ffmpeg/include`.
