RepackToHAP - convert standart RTP packet with OPUS to HAP packet We expect that: - incoming packet will be 20ms duration and only one frame per packet - outgouing packet will be 20ms or 60ms duration - incoming sample rate will be any (but not very big if we needs 60ms packets for output) - outgouing sample rate will be 16000 https://github.com/dadav/go2rtc/issues/667.
