[FFmpeg-devel] [PATCHv3] lavf: add av_guess_frame_sample_aspect_ratio function

[Joakim Plate]

Just thought i'd chime in here. We (xbmc) ended up using that special
handling of stream aspect being 1:1 and codec aspect not being 1:1 to
solve a few samples we found in the wild. Thing the where mp4's
recorded by some camera if i remember correctly. So i'm sort of in
favor of that solution even if it's ugly.
