Vista Video Playback broken



  • Phonon video playback, via DirectShow, on Vista 32 bit SP2, is not working (I have not encountered this problem on other Windows versions including Win7 64-bit and XP). The standard VideoWidget is not painting in the video area, although it is playing the audio back.

    I've encountered someone else with this problem but I haven't found an explanation of what's going on anywhere:

    http://bugreports.qt.nokia.com/browse/QTBUG-20068?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#issue-tabs

    Does anyone have a clue, here? This seems like the kind of issue that more people would have encountered and require a fix for.

    By the way, I've seen this on both Qt 4.7.2 and Qt 4.7.3, with a PySide application. I don't have a clear way to debug the Phonon code as I'm using the PySide binaries.

    Any pointers would be greatly appreciated!



  • Can someone at Nokia comment on this? Has the VideoWidget been QA'd at all recently?
