There is little advantage in allocation AVPacket in the heap. In the
“decoding_encoding.c” example, the packet structure is placed on stack
and reused during encoding; but for each frame it is re-initialized
av_init_packet(&pkt);
pkt.data = NULL; // packet data will be allocated by the encoder
pkt.size = 0;
Anyways, it's good that you succeeded to resolve your problem.
