- Reuse muxer patterns from voice (muxer.ts) + session recording. `muxToMp4(rawPath)`: `ffmpeg -f h264 -i raw.h264 -c copy -movflags +faststart
- Persist in voice_recordings / new video_recordings table; upload via teleuploader. out.mp4`, deletes raw on success (>=1B mp4), keeps it on failure.
- Output: `<RECORDINGS_DIR>/<uid>/video-<ssrc>-<ts>.mp4`.
- ffmpeg is on the gateway runtime PATH (pkgs.ffmpeg-headless, already in the
Nix buildInputs for the music/GoLive players).
- Test: `tests/videoReceiver.test.ts` muxToMp4 case (real ffmpeg, generates a
tiny baseline h264, asserts mp4 non-empty + raw deleted; skipped if no ffmpeg).
