+# 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
+```
