[FFmpeg-devel] [PATCH 2/6] sink_buffer: change get_buffer_ref error code to BUG.

[Nicolas George]

request_frame is supposed to either push a frame or
return a failure code; therefore, if it does neither
when asked to by av_buffersink_get_buffer_ref,
it is an internal bug in some filter that needs to be
fixed (AVERROR_BUG) and not a bug due to external
conditions (AVERROR(EINVAL)).
