Pursuant to DVD Jon’s post about compiling and using the SMPTE reference VC-1/VC-9/WMV3/WMV9 decoder with VLC, I wrote an FFmpeg module to use the same reference code. Next, I will try to adapt it to xine. Though I hope we do not grow too collectively complacent with this decoder.

I tried decoding 3 different WMV3 videos from 3 unique sources. The reference decoder seemed to work fine on 2 videos but not on the third.

The third videos fails on all frame decodes, usually tripping errors about “FATAL ERROR: DecodeACRunLevel: AC coef array overrun”.
