[FFmpeg-devel] [PATCH 1/2] avcodec/vp9_raw_reorder_bsf: Fix leak of cached packet

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

In case the BSF has not been drained before flushing/closing,
the context's next_frame might be set; yet it is not freed
in flush or close. The former only zeroes it (which automatically
causes a leak in case it was set). So do this when closing
and flushing.
