opus - Nov 2013 - Please help me decode this webrtc chrome conversation

Hi.
I made a webrtc relay with recording and dumped the SDP requests and RTP packets
into files.
Then I made a java decoder based on jitsi.

Although the files contain all the needed info: encription keys, codec
info, timestamps, etc., I could only decode one side in one of 2
conversations.

For example, the RTP payload is decrypted successfully, but
opus_packet_get_nb_samples() or opus_decode() return
OPUS_INVALID_PACKET.


payload-0.dat , contains my real voice. Decoded successfully.

payload-1.dat , contains looped beep recorded with a virtual
microphone. While recording I was hearing it, but I can't decode the
file.

Are you sure you didn't forget to strip the RTP header before decoding it?

Yes, I parse the RTP header, decrypt the payload and then feed the
decrypted data to opus. Besides, opus_decoder_get_nb_samples() on 1st
packet returns reasonable number 960, but then opus_decode() fails.
