# FFmpeg CLI wrapper

This package restores the existing process-based FFmpeg wrapper and adds
fragmented-MP4 HLS VOD generation.

The wrapper uses `fork`/`execvp` with explicit arguments instead of building a
shell command. FFmpeg must be installed on the machine running the target.

```c
Fmp4HlsOpts options = ffmpeg_fmp4_hls_opts_default();
options.codec = FFMPEG_HLS_VP9_OPUS;
ffmpeg_video_to_fmp4_hls(
    "input.mp4",
    "output",
    "sample",
    &options);
```

The wrapper supports VP9/Opus and H.264/AAC fMP4 renditions so callers can
build codec-compatible HLS master playlists.

```bash
bazel test //third_party/ffmpeg:ffmpeg_hls_test
```
