[Stefano Sabatini]

ffmpeg | branch: master | Stefano Sabatini <stefano.sabatini-lala at poste.it> | Tue Apr 26 11:51:50 2011 +0200| [f4e043ff63935a71b98a36bc98b501c36ceadb92] | committer: Ronald S. Bultje

qpeg: use reget_buffer() in decode_frame()

Decoder relies on previous frame data, so use reget_buffer().

This also set frame->reference to 3, as the frame will be requested
unmodified later so it shouldn't be modified by the application.

Fix playback of file Clock.avi.
