See b2bed932.

fdct is only initialized if encoders are enabled.

Even thought a generic solution would be more relevant, this is
currently helpful while debugging.

Currently the code passes some nonsense values as
references instead, causing corruption with NVidia's
and assertion failures with Mesa's implementation.
For non-corrupted input this mostly happens in
interlaced bitstreams, e.g.
http://samples.mplayerhq.hu/V-codecs/WMV9/interlaced/480i30__codec_WVC1__mode_2__framerate_29.970__type_2__preproc_17.wmv.
The != VDP_INVALID handle assert does not trigger
(and probably is quite nonsense) because the frames
are initialized to 0.

We read 2 bytes for 15 out of 16 pixels, therefore we need to
have at least 30 bytes, not 16.
