    Description

      I have a minimal qml example with 3 buttons (forward, play, pause) and a VideoOutput/MediaPlayer.

      When the pause button is clicked, the video pauses. But when the play button is clicked aufterwards, the video fails to play. It seems to hang.

      The video also hangs, when the forward button is clicked (maybe setting the position triggers a pause internally?).

      This bug does not happen with every video. Please find a test video in the attachment, which triggers the bug (some other videos I tried work fine). It must be copied next to the binary to be found!

       
      Somehow, this is related to the audio of the video. When I comment out the following line

      audioOutput: AudioOutput { }

      everything works as expected.

      This bug was observed with the windows media foundation backend. The mentioned minimal example is provided in the attachment.
