Hi Randell, Yes, I am trying to connecting from our device to FF 33. I think the problem is RTP format incorrect? Because all packet are encrypted by DTLS, I don't know how to get the RTP packets by using Wireshark. However, I run FF 33 on linux, and try to collect more error information. And I see -1747978496[7f50aa95bb60]: [Socket Thread|WebrtcVideoSessionConduit] VideoConduit.cpp:1111: ReceivedRTPPacket RTP Processing Failed 12606 After checking the source code of FF 33, seem the error code is 12606. Does anyone know what does it mean? NOTE: Because I am still not sure this is FF bug or not, I still hope can discuss this issue here. Thanks. _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
