QMediaPlayer fails to play local MP4 video on Symbian^3 device (N8) and throws Symbian error code -12017

QMediaPlayer fails to play local MP4 video and throws Symbian error code -12017 when using QVideoWidget. Issue may not be visible on the first few attempts to play video, but in the end, the playback of video fails. User may need to restart test application a couple of times in order to be able to reproduce the issue.

Video clip was created with the device and can be played with platform's media player and with QMediaPlayer/QVideoWidget combination (but not every time). When playback of video fails the audiotrack of the video can be listened without video.

The resolution of the video clip was 640*480.
