You cannot request a buffer from the next filter using get_video_buffer
and changing it before sending it to that filter. This is broken for the 
pad filter at least.

If you want to avoid any picture copying you have to override 
AVCodecContext->get_buffer and reget_buffer by new functions that use 
get_video_buffer.
