Not dumb, but the answer was in the first sentence of the commit message.
The corresponding code is in ff_read_packet():
if (!pkt->buf) {
AVPacket tmp = { 0 };
ret = av_packet_ref(&tmp, pkt);
if (ret < 0)
return ret;
*pkt = tmp;
}
And av_packet_ref() creates a refcounted buffer if the given one is not
refcounted.
