Convert MKV to MP4 for wider playback support.
Requires engine
MKV to MP4MKV to MP4 is fully built. It cannot run in this deployment because a dependency has not been configured.
- What it needs
- ffmpeg.wasm, or a server-side ffmpeg worker
- Why it is not on yet
- Video and audio work needs ffmpeg. The in-browser build keeps files private but adds roughly 25 MB of WASM on first use, so it must be lazy-loaded behind an explicit prompt. Large files need the server worker instead. Neither is bundled here.
