The idea

There should be an upload filter that remuxes ISOBMFF files with the moov atom at the start of the file (FFmpeg command line option for reference: -movflags +faststart).

The reasoning

Quite often when users upload videos in .mp4 containers, they are not muxed properly for streaming.

Fixing those with a filter will allow clients to get an index and stream ISOBMFF media files without having to download the whole thing or do range requests. This is faster/more efficient and also solves problems with Misskey and its forks (because the web framework those use to serve media files, shockingly, has no support for range requests).
