[FFmpeg-devel] [PATCH] fix shifted picture in AMV video decoder when height is not dividable by 16

[Vladimir Voroshilov]

Hi, All

If picture height is not dividable by 16, AMV related flipping code in
mjpeg decoder does not work correctly.
You can easily see height%16 lines of garbage at the top of picture
while the same number of bottom lines are not visible.

Attached patch adds code which moves three YUV planes in buffer up
after decoding picture.

Comments and (especialy) optimizations are welcome.
