Video Playback Problem

[curtis]

Hi, I am using Qt 5.8 and MSVS 2013 on Windows 10 and using MediaPlayer to play videos. 19 out of 20 times this plays vidoes fine but occasionally the video will play with audio but the screen will just flicker. It looks as if a single pixel from the video is taking the whole video output. The media state and playback state appear normal and there are no errors. Any ideas?

MediaPlayer
    {
        id: player
        source: root.source
        autoPlay: false
        autoLoad: true
        loops: 0
}
VideoOutput
    {
        id: videoOutput

        source: player

        width: root.width
        height: root.height

        fillMode: VideoOutput.Stretch
    }
