I can confirm that this patchset fixes SA10125.vc1 and a few other files.
The remaining files with issues are:
SA10135.vc1: Shows an error message ("missing cbpcy_vlc") and produces
SA10178.vc1: 18 frames ok, last 7 frames are different
Several samples show an error that luma scaling and chroma scaling are
not supported and produce incorrect output, for example SA00048.vc1.
A few samples use pan-scan which is not supported by FFmpeg, for
example SA10164.vc1 - a warning is shown.
Thank you, Carl Eugen
