WebCodecs Player

Low-level .mov/.mp4 playback using the WebCodecs API (VideoDecoder / AudioDecoder) + mp4box.js demuxing. The file is streamed — only needed sample ranges are read, so multi-GB clips work. No <video> element is used.

Choose .mov / .mp4 0:00 / 0:00

Drop a .mov / .mp4 file here, or choose one above.
