ffmpeg | branch: master | Ronald S. Bultje <rsbultje at gmail.com> | Sun Jan 20 22:12:35 2013 -0800| [e6bc38fd49c94726b45d5d5cc2b756ad8ec49ee0] | committer: Ronald S. Bultje
wmv2: move IDCT to its own DSP context.
This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
and get corrupt output.
Fate tests for all wmv2-related tests change, because (for some obscure
reason) they forced use of the MPEG IDCT. You would get the same changes
previously by not using -idct simple in the fate test (or replacing it
with -idct auto).
