[04:02] <durandal_1707> how to read packed side data before reading packet data?
[04:29] <michaelni> durandal_1707, iam not sure i understand what you mean by "before reading packet data" but av_packet_split_side_data() is how merged side data is split 
[04:33] <durandal_1707> michaelni: i cread pallete data before packet data
[04:34] <durandal_1707> the point is to avoid useless memcpy
[04:34] <durandal_1707> and malloc
[04:36] <michaelni> av_packet_new_side_data() + manually filling the packets data/size/destruct should work
[04:36] <michaelni> but isnt pretty ...

[05:09] <CIA-41> ffmpeg: This allows filtering of linker flags the same was as already
