[FFmpeg-devel] [PATCH V4 2/4] libavfilter/buffersink.c: unref private_ref when frame leaves libavfilter

[Guo, Yejun]

private_ref is for internal use by a single libav* library.
It has to be NULL when ownership of the frame leaves the respective library,

buffersink is the last step when the frame leaves libavfilter, so add unref here.
