I still have the same problem, too .mp4 and several .flv files are also not playable.
I checked out the video codecs and found out that all files, no matter if they were a .mp4 .mkv .flv, used the h264 video codec. I got this from the information ffmpeg gave me.
I added an .flv video as attachment, but it should do as well.
