The name of the directory is h264_aspect_ratio. The uploaded sample contains 
two sections with different aspect ratio: advertisments in 4:3 (first in 16:9 
letterbox, then 4:3 fullscreen), then olipic studio in 16:9 anamorphic. Both 
patched ffplay and softdevice (ffmpeg-0.4.9_p20090201) switch the aspect 
ratio correctly while playing.
