Steps to reproduce: 1. Simple HTML page which includes video element with type mp4 content and audio element with mp3 content 2. Qt application with QGraphicsWebView 3. In application PluginsEnabled 4. Run application 5. Play video 6. Play audio Expected results: - The video and audio are played Actual results: - It looks like the video and audio start to play because the ‘play’ indicator is changed to ‘pause’ indicator, but neither is actually played. Windows Media Player plays both fine. The issue can be reproduced with Qt 5.0.0. Attached an application that can be used for testing purposes. The multimedia and images folder don’t have any content do copyright issues, but the issue can be reproduced with any valid mp4 and mp3 files.
