On: Stupid solutions: Live server push without JS

You cannot use MP4 for live streaming. The file cannot be demuxed properly if the moov soon is incomplete. Frames cannot be located, it is impossible to decode it in the end. With live streaming, you don't ever have the full file until the end of the event, which is why you cannot stream it. Video streaming with a complete file is possible of course, but that is nothing special nor related to this discussion.

You only need:

    moov [moof mdat]+

This allows you to build a never-ending fragmented mp4. This isn't a new technique. It's been around and used for livestreaming for years.
