It is incorrect to modify the frame properties after passing them, since VTCompressionSessionEncodeFrame takes reference and we have no control over when it's being used. In fact, the code can be simplified. We just preallocate the frame properties for keyframe requests, and pass NULL otherwise. https://bugzilla.gnome.org/show_bug.cgi?id=748467
