    Hello,

    i am running Linux and when i try to play an mp4 video in Qt i get the following message:

    • Warning: "No decoder available for type 'video/x-h264, stream-format=(string)avc, alignment=(string)au, level=(string)4.2, profile=(string)high, codec_data=(buffer)0164002affe100352764002aac34c80780227e5c05b808080a000007d000030d41d0c000e4e00000e4e1d77971a18001c9c00001c9c3aef2e1f088451601000428ee3830, width=(int)1920, height=(int)1080, framerate=(fraction)50/1, pixel-aspect-ratio=(fraction)1/1, parsed=(boolean)true'."

    The audio is actaully working great but i cannot see the video., Any help?

      Seems like in linux Qt uses gstreamer. I think you are missing some plugins.
