Comment (by cehoyos):

 Please always post all necessary information here on the bug tracker, do
 not use external resources, they may disappear!

 There are two possibilities to fix your original problem (performance on
 transcoding from vc1 to wmv2 is too low):
 The first is to implement wmv2 multi-threaded encoding. Given that the
 task is not trivial and this codec was deprecated by Microsoft years ago,
 I am not sure how likely this is to happen.
 The second is to implement vc1 multi-threaded decoding. While this is
 probably not simpler, vc1 decoder is an important part of libavcodec, I
 would therefore suspect that the chances are (very slightly) higher,
 consider opening a second enhancement request (or wait for me to do it).
