Spot on! Exactly what I was thinking about some day ago. Unfortunately it's
hard to tell which version xbmc is using since gas-preprocessor.pl lacks
version info. I did a quick check and compared a version I found online,
and sure enough, there were some address alignment updates in there among
other stuff. Didn't find any gas-preprocessor.pl in the ffmpeg repo thus
where do you find one which is supported by ffmpeg?
