Firefox unable to play animated gif and mp4 from the following link:

https://bugreports.qt.io/browse/QTCREATORBUG-18666 https://bugreports.qt.io/secure/attachment/65386/Kazam_screencast_00000.mp4 https://bugreports.qt.io/secure/attachment/65384/Peek%202017-08-01%2021-41.gif

IMPORTANT:

  • I get same result in case I disabled all add-ons
  • Chromium run them without any problem

I use

  • Linux Mint 18.2 x64 xfce
  • Firefox 54.0 (64-bit)

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!
