VC-1 Decoder and Bitstream Conformance
VC-1 is also known as Windows Media Video 9. See this screenshot of VLC playing the Shuttle Discovery Launch video using the VC-1 reference decoder under GNU/Linux.
The reference decoder won’t be publicly available until VC-1 becomes a SMPTE standard. Update: the reference decoder is now publicly available at smpte-vc1.org.

ooh, cant wait for open source wmv9 decoder, wonder how much faster it will be vs binary codec…
That reference decoder is gone now.
Yes, while the reference decoder is not available now, is there any copy for that?
Want “VC1_reference_decoder_release6.zip” share.
The link to the reference VC-1 decoder is not working. Has a new location been created?
Could you also point to some links which elucidate differences between VC-1 and WMV9 codec-only?
Anybody got a copy of the VC1 reference decoder code? The link does not help. Any other link to it?
