[FFmpeg-devel] [PATCH] ultimotion: use reget_buffer() in ulti_decode_frame()

[Stefano Sabatini]

Also remove unnecessary call to avctx->release_buffer(). reget_buffer
is required since apparently the coded needs to be passed the previous
frame data again.

Releasing the frame and using get_buffer was working only in the case
get_buffer() was returning the old frame data again, and resulting in
playback artifacts otherwise.

Fix trac issue #78.
