- The test video is the mp4 one from http://camendesign.com/code/video_for_everybody/test.html
When I start the application the video shows up fine, console output is like this:

When the video has finished the first time I only see some random colors on the screen, looking maybe like one pixel has been scaled to the whole viewport, console output are these lines:
qt.multimedia.video: updatePaintNode: deleting old video node because frame format changed qt.multimedia.video: updatePaintNode: no frames yet qt.multimedia.video: updatePaintNode: Video node created. Handle type: NoHandle Supported formats for the handle by this node: (Format_YUV420P, Format_YV12, Format_NV12, Format_NV21, Format_UYVY, Format_YUYV)
They repeat every time the video is finished. This does not depend on the video, it happens with many.
