While a video sent from riot-android has playback controls in all riots:

The same video sent from riot-web in ff isn't playable:

Does your firefox have anti-fingerprinting enabled? Anything which breaks canvases can causes the file to be mis-detected as not being a video.

I don't know, but ff with a new clean profile works the same.

BTW, image files are shown correctly sent from the same ff.

The same as #14328, this issue is HEVC related.

The last screen is from android. While it can play HEVC, the video has no controls.

Right, the issue is if the sending client doesn't support HEVC then it can't verify that the file is a video so it sends it as m.file and not m.video
