[FFmpeg-devel] [PATCH 2/2] avfilter/vf_uspp: Fix leak of packet side data

[Andreas Rheinhardt]

The uspp filter uses a special option ("no_bitstream") of
the Snow encoder to suppress it from generating output.
The filter therefore did not unref the packet after usage,
believing it to be blank. But this is wrong, as the Snow encoder
attaches quality stats side data to the packet.

If there were a fate test for this filter, this would have been found
and fixed long ago.
