WMV on Linux

[japanmoran]

We are finding sync probs with audio when trying WMV transcodes....

WMVs have been windows media video 7.

Audio has been windows media audio 7 and some kind of 9.1 audio codec.

Should this be possible?

The secret to WMV is to use the most current possible software you can.

wmv7, is really wmv1 and you should never have an issue with these files.

wmv8, is really wmv2 and you should hardly ever have issues with these file if you're using Flix 8.0.4.4 or later.

wmv9, is really wmv3 or sometimes know as vc1. If you're having issues with audio sync this is probably the culprit. Fortunately this is being fixed fairly quickly.

wmv3 native decode was added to ffmpeg in August and should be fully tested and working by now in mplayer. Flix 8.0.5.0 should have pretty good WMV3 support, but it may be worth your time to build your own mplayer with the most recent CVS checkout. If WMV3 is really important you may want to watch the ffmpeg/mplayer dev lists and update as bugs you care about get fixed.
