That's too bad.
Do you know who has done any BF related work on ffmpeg lately?  I see  
that 0.5 lists Blackfin optimization as one of the changes.  Any idea  
about how to track down those details?  Or does that just mean that  
stuff that Marc did a few years ago?

Some of above info might help focus the search some.  I see that a lot  
of the blackfin related code is slightly different between 0.5 and  
svn-11114.
