MP4 Video ist not playing Firefox

[anon21401411]

Hey,

maybe the following information is also valid for your problem?

Video getting Downloaded instead of playing in owncloud 10.6.0

Like @eneubauer said: software issue, probably due to missing codecs in Firefox Ubuntu. Choosing the right encoding for web video is a real pain… I am currently using ffmpeg for encoding using vcodec h264 and acodec aac - this gives me best compatibility at the moment
