Hi!

I finally found an issue that is fixed with the new asf demuxer:
Video in ​http://samples.ffmpeg.org/V-codecs/MSS1/GipsyGuitar.wmv 
freezes for ten seconds after 110 seconds, this does not happen 
with -f asf_o.
Attached patch fixes this issue, fate passes, no other sample 
tested with the patch applied.

Please comment, Carl Eugen
