From 8a81820624ada4d339aeb2150ad5c2b36b12860c Mon Sep 17 00:00:00 2001 From: James Almer Date: Mon, 17 Aug 2020 12:03:50 -0300 Subject: avcodec/packet: move AVPacketList definition and function helpers over from libavformat And replace the flags parameter with a function callback that can be used to copy the contents of the packet (e.g, av_packet_ref and av_packet_copy_props).
