[Ffmpeg-devel] [PATCH] increase picture buffer alignment to 16-byte on x86

I was doing some sse2 code with an ffmpeg buffer and was surprised to  
find it crashing.
This turned out to be because avcodec_default_get_buffer was aligning  
the U/V buffers to 8-byte instead of 16-byte alignment. As 16-byte  
alignment works fine on PPC, the attached patch changes it to match  
on x86.

Although if there's a reason for this, I can certainly just go to  
using movdqu.
