From: Aman Gupta <aman@tmm1.net> This callback will be used by the VideoToolbox H264 hwaccel so that it can receive SPS and PPS NALUs. VideoToolbox requires PPS changes to be fed into the decoder session, and for the session to be recreated when the SPS changes. --- libavcodec/h264dec.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+)
