### Added ### Added
- **MP4 input (`mp4://` as a source)** — a progressive-MP4 demuxer, the inverse
of the muxer: it rebuilds the title + per-sample index from `moov`/`stbl` and
streams samples back as PES frames, so `mp4://` now flows to **any** sink
(`mp4:// mkv://`, `mp4:// audio://`, `mp4:// json://`, …). Round-trip is
frame-exact (verified `iso:// mp4://` → `mp4:// mkv://` preserves every video
and audio packet). Progressive MP4 only; fragmented (`moof`) is future work.
- **Native MP4 output (`mp4://`)** — a progressive ISO-BMFF muxer - **Native MP4 output (`mp4://`)** — a progressive ISO-BMFF muxer
