--- Comment #4 from Jer Noble <jer.noble at apple.com> ---
I've only managed to catch this bug live once, in a shipping version of Safari. Some dtrace debugging showed that MediaPlayerPrivateAVFoundationObjC::videoOutputHasAvailableFrame() was repeatedly returning false, due to [m_videoOutput hasNewPixelBufferForItemTime:[m_avPlayerItem currentTime]] returning NO. <http://trac.webkit.org/browser/trunk/Source/WebCore/platform/graphics/avfoundation/objc/MediaPlayerPrivateAVFoundationObjC.mm#L2204>
