Merge palette-only header with actual video frame.
This fixes the video frame pts (off by one for each MVIh) and makes the "key frames" decode stand-alone (MVIh contains only palette, such a palette-only frame being marked as key frame is not really correct). Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
