Commit 7873bede (https://bugzilla.gnome.org/show_bug.cgi?id=760774) changed the behaviour of qtdemux to call gst_qtdemux_configure_stream() for every new moof. When playing a protected stream, gst_qtdemux_configure_stream() calls gst_qtdemux_configure_protected_caps(). The gst_qtdemux_configure_protected_caps() function takes the original media format, puts this in a field called "original-media-type" and then changes the caps to "application/x-cenc". The gst_qtdemux_configure_protected_caps() did not handle the case of being called multiple times, causing it to incorrectly set the caps. The second call was causing the caps to be set to: application/x-cenc, original-media-type"application/x-cenc" This commit makes gst_qtdemux_configure_protected_caps() check that the caps have already been transformed, so that it only gets changed once. https://bugzilla.gnome.org/show_bug.cgi?id=761769
