Video not retransmitted: why isn't Asterisk forwarding the video data?

Asterisk Asterisk Support
1

Hello everyone.

I’m working on an Android to Desktop (Web browser) WebRTC call implementation. I am able to successfully istantiate the call, receive and transmit audio and see the video from the desktop on the mobile. However, I am not able to see the video from the Android camera on the Desktop.

Let’s talk about this video that I am not able to see. You’ll find, attached, the Asterisk log and Wireshark data, showing that Asterisk is actually receiving the video from the Android device, but it’s not sending it to the Desktop Chrome. Using the Chrome tools, I see the only incoming data through the WebRTC connection is audio (I can see it due to low packet size).

Any idea about the cause of this issue?

Your Wireshark is filtered to only show one flow. Have you also looked at “rtp set debug on” to see if it is actually being received and decoded? Have you done a test not in a call with the device having a problem using Echo to echo back received media?

You basically have to isolate it down.

Also didn’t you create a post a week ago with this same problem and I responded with the same last thing?

Hello jcolp,
thanks a lot for helping here.
I also tried calling the Echo and the scenario is exactly the same.
Practically, I see on asterisk:

== Setting global variable ‘SIPDOMAIN’ to ‘videoconf.i-tel.it’
== DTLS ECDH initialized (automatic), faster PFS enabled
– Executing [echo@user-in:1] Answer(“PJSIP/648-00000052”, “”) in new stack

> 0x7f90b8136390 – Strict RTP learning after ICE completion
– Executing [echo@user-in:2] Echo(“PJSIP/648-00000052”, “”) in new stack
> 0x7f90b8136390 – Strict RTP switching to RTP target address 192.168.5.110:59071 as source
> 0x7f90b8136390 – Strict RTP learning complete - Locking on source address 192.168.5.110:59071

and only audio is echoed back to android.
I don’t have the video stream despite snoop shows this is sent from android to asterisk on same port as audio (59071).
What I also noticed is that asterisk is only locking on one source address while I would have expected one for audio and one for video
on same link.
No error messages appearing on asterisk to clearly identifying an issue.
I have also attached snoop where .110 is android and .220 is asterisk.
What could be the problem?

Thanks again

What is actually negotiated? What is the SIP trace?

I had another run of calling Echo this time with PJSIP logger enabled. Hope this is helpful. Thanks again.

Nothing stands out. We do this every day, so it’s likely something browser side or specific to your configuration. You’d need to dig into the code most likely.

Hello,
I’m stumbling on the same issue and I can confirm that with FF this works perfectly.
It seems a specific problem between Chrome and Asterisk but can’t figure out which of the two is to blame.
I only noticed that for the video part, Chrome adds the ssrc-group:FID attribute which is missing in the FF’s SDP.
Does Asterisk/pjsip support that?
Any other troubleshooting I could run to find rootcause?

Thanks
