The issue i mentioned was caused by the fact i timestamped outgoing
audio with just incrementing pts by duration, relatively to previous
processed frames. Now i added checks for gaps in received packets. (I
mean, if you read by UDP, you can loose series of packets).
The logic is like
int64_t gap = pkt.pts - pkt.duration - current_out_pts;
if (gap) {
printf("Gap detected, shifting audio timestamps by %d\n", gap);
current_out_pts += gap;
}
The issue, of course, was not specific to libav fork only.
