Description
As a side note, I must say that lavf ASF demuxer outputs wrong data, so for example eleventh or twelfth frame in http://samples.ffmpeg.org/V-codecs/MSS1/screen_codec.wmv is demuxed wrong compared to MPlayer. And of course it causes decoding errors.

Yes, asf demuxer is broken, there should be only one open bug report for it.
