[FFmpeg-devel] [PATCH 00/18] cbs: Use ff_bsf_get_packet_ref etc.

[Andreas Rheinhardt]

Hello,

this patchset is mainly about switching the bitstream filters using cbs
from ff_bsf_get_packet to ff_bsf_get_packet_ref (except trace_headers,
which also uses it). But in the course of doing so, I also found several
other (usually small) things to improve and this is included here.

This partially conflicts with my earlier patchset [1]; I will rebase it
on top of this and resend it.
