Some background - https://forum.cloudron.io/topic/10723/mp4-files-not-playing-in-safari-on-iphones

I was debugging this a bit. Initially, I thought this was because of "/raw" in the source URL. I renamed this to raw.mp4 but it doesn't need to matter for Safari.

It looks like there is some issue with the response XBackBone sends for content range requests. See https://stackoverflow.com/questions/30199261/why-wont-safari-play-file-without-extension-in-video , rwf2/Rocket#806 , jooby-project/jooby#523 and https://stackoverflow.com/questions/32996396/safari-9-0-can-not-play-mp4-video-on-the-storage-server for related issues. I am still debugging , will update this issue as I find any more info to add.

Removing the autoplay tag for video makes it work on iphone. But it still doesn't work on desktop safari.

FWIW, playsinline doesn't seem to help on desktop safari.

I dont have any Apple device to test Safari sadly, if you find a way to make it work feel free to open a PR
