00134 If you notice errors in the align stuff, need more alignment for some ASM code
00135 for some CPU or need to use a function with less aligned data then send a mail
00136 to the ffmpeg-devel mailing list, ...
00137 
00138 !warning These alignments might not match reality, (missing attribute((align))
00139 stuff somewhere possible).
00140 I (Michael) did not check them, these are just the alignments which I think
00141 could be reached easily ...
00142 
00143 !future video codecs might need functions with less strict alignment
