new test video

I've tested the patch. Now playback starts, but I get this error multiple
times, when I play the new (longer) video file:

 ** (gst-launch-1.0:1688): CRITICAL **: gst_video_frame_map_id: assertion
'info->height <= meta->height' failed

I started gst-launch in gdb with G_DEBUG=fatal_criticals and I get this:
