I seem to have mp4 playback working on OS X out of the box, but my video did not have any sound track. I have not knowingly installed any gstreamer plugins in the machine.
I made a small testcase included in https://bugreports.qt.io/browse/QTBUG-44157 that plays the included mp4 fine on OSX. On iOS there is some accidental DRM, the first showing is ok, and subsequent showings are corrupted :) Harri On 27/01/2015 15:49, René J.V.
