[FFmpeg-devel] [PATCH] smacker: remove unnecessary call to avctx->release_buffer in decode_frame()

[Stefano Sabatini]

The release_buffer was cleaning the provided frame, thus causing the
successive call to avctx->reget_buffer() to allocate a new frame.  In
case the returned frame was not the same one previously returned but a
new one with different data, it resulted in artifacts.

Fix trac issue #87.
