    ]

And in wireshark i can see how udp packages forwarded from ip cam to janus.

As far as I can understand the problem occurs because the Janus sends "a=fmtp:96 profile-level-id=420029;level-asymmetry-allowed=0"
I'm right?

[Anton Vladimirovich]

or it sends ip camera?
whether there ip camera that can use the correct parameters?

Firefox rejected the stream, just look at the local sdp:

m=video 0 RTP/SAVPF 0

Not sure, you'll have to enable debugging in Firefox to see if that's what's causing it to reject the stream. Maybe H.264 support is not enabled in about:webrtc? 

[Lorenzo Miniero]

Oh just saw the profile level ID: then yes, I guess that's it, AFAIK only the baseline profile is supported in Firefox. See if you can change the profile to be used in the IP camera settings.

H 264 are supported and strimings work. The problem with the type rtsp.
So if I find the camera where it will be possible to set the baseline profile - fmtp change to 96 profile-level-id=42e01f\;packetization-mode=1 ?

[Anton Vladimirovich]

I wanted to say "126 profile-level-id=42e01f\;packetization-mode=1"

Just see if you can change the profile, the payload type (96 vs 126) is done by Janus automatically).
