Only a black video frame. I can confirm this issue with version 4:4.14.1-1 with both the KHTML and the WebKit mode. It does not work for 4:4.8.4-2, too. The corresponding upstream bug report seems to be https://bugs.kde.org/show_bug.cgi?id=229218 Visiting http://www.quirksmode.org/html5/tests/video.html, this seems to be a H.264/MP4 related problem, as both WebM and Ogg/Theora work (tested with 4:4.14.1-1 and WebKit) and only H.262/MP4 plays sound without pictures. I activated some debugging in kdebugdialog, but I couldn't spot anything obvious, though that might have gone lost in the noise. It might be related to this bug report: https://bugs.kde.org/show_bug.cgi?id=253061 If that should be true, QtWebKit would be related. This seems similar to this report: https://github.com/QupZilla/qupzilla/issues/573 In http://stackoverflow.com/questions/3066055/qtwebkit-problems-playing-html5-video it's mentioned, that Phonon might also be relevant. Switching the phonon backend from gstreamer to vlc seems to stop Ogg/Theora support on the above test page, although it dose not change the support for H.264/MP4 videos. But there definitely seems to be a relationship. I tried Rekonq and the support on http://www.quirksmode.org/html5/tests/video.html is identical to that of Konqueror using Konqueror's WebKit mode. So it does not seem to be something Konqueror specific. Then again, Arora, another WebKit based browser, works and supports all three files on testpage mentioned above. Arora is linked against Qt5 and Qt5WebKit, while both Konqueror and Rekonq are linked against Qt4 and the latter one also against libQtWebKit version 4. So it really seems to be QtWebKit4 related.

Bug#756411: Reason found
Hello, more or less by accident I have found the reason. The distorted appearance comes from setting "Composit-Type" to Xrender and "Qt-System" to Nativ. All other settings work. Especially for desktop effects OpenGL is needed. Markus
