OK, then convert to a compatible format upload that (however to fully 
support the video tag, you'll need multiple formats to match what the 
browsers want- mp4/ogg/webm).

BTW, because of the way ogg containers are constructed, you should have 
better luck with them than mp4.

Just do it, life will be much simpler.

https://web.dev/media/ has some useful info about using the video tag.

You're much better off pre-converting the files. Is there any specific 
reason you can't do that?

Later,
