Also, please add "timestamp" to the list of NSPR_LOG_MODULES
I attached firefox log with timestamp. Please wait for pcap files.
I found another error message on both logs.
In FS (freeswitch) log, there is no message that it has received RTCP
packet. There is such message with chrome.
There are also error messages regarding RTCP in FF (firefox) log:
- Error unprotecting SRTCP packet
- Couldn't write RTCP packet; SRTCP not set up yet
The RTCP DTLS-SRTP flow is eventually ready ready (around 2.5 seconds
after createAnswer()/etc), and we start trying to deliver them. But, as
you note, they fail to be decoded, which implies either a bug in their
DTLS-SRTP key extraction code (like using the SDES key by mistake), or
incorrect settings for SRTP (auth tag size, etc). We are sending RTCP
packets; the problems suggested above would likely mean they'd fail to
decrypt ours, but they may not log it.
Equally worrisome is that I don't see the rtp DTLS connection finish
opening (no SSL handshake completed log message).
