I did my tests on SDK v11. All AVIs (WMV + AC3) could be multiplexed to WMV. In the first step I demuxed the AC3 audio and ds copied the WMV video to WMV. I then coded the audio in WMA and muxed both streams with the Windows Media Stream Editor.
What sample and what profile caused the crash? Can you give details or samples?
The profile is necessary for data, that is not available from the AVI source. If you compare the streams in ASFView from wmvmuxer and other asf muxers, you will see that important objects are missing in the other streams. The missing device conformance templates and codec list objects can cause probs on the Sigma chip, and when streaming and when using other WMV tools.
I admit it is unusual to have a profile for muxing and I am thinking of alternatives.
