Original commit message from CVS:
* gst/asfdemux/gstasfdemux.c: (gst_asf_demux_add_video_stream),
(gst_asf_demux_process_ext_stream_props):
Instead of adding a fixes 25/1 framerate to the video caps, use the
average frame duration in the extended properties of the video stream as
the framerate. Fixes #524346.
