I forgot to mention error message of mp4 file:

Video can't be played because the file is corrupt

I see the same "Video can't be played because the file is corrupt" error. This is probably because the video is encoded with "Planar 4:4:4 YUV" The file plays for me on Linux with VLC.

Browser Console on Nightly: 

Media resource https://bugreports.qt.io/secure/attachment/65386/Kazam_screencast_00000.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005)
Details: mozilla::SupportChecker::AddMediaFormatChecker(const mozilla::TrackInfo&)::<lambda()>: Decoder may not have the capability to handle the requested video format with YUV444 chroma subsampling.

I wonder why Chromium plays it on same machine without any problem although both browsers suppose to get same encodings!
