MP4 container part, solved --> https://lemmy.ml/post/22627660

Funny when I open .mp4 container version of it, by file path (url bar) like file:///X:/path/FooBar.mp4 it works, so Firefox can Open it… (now still to make it work inside an html page 😑 )

for .mkv it trigger a file download…

(audio): Codec: MPEG AAC Audio (mp4a)\
