Comment:

 Replying to [comment:7 Lastique]:
 > No. The delay is indicated by `avcodec_receive_packet` returning
 `AVERROR(EAGAIN)` and no packet. Subsequent calls returning packets are
 expected to return timestamps that were passed on input.
 >
 > As it is, the encoder does not introduce a delay but a negative offset
 in timestamps.

 You misunderstand, it is indeed encoder delay, or audio priming is another
 name for it:
