No audio when webrtc mobile clients connected in different network

No audio when webrtc mobile clients connected in different network - webrtc

In my current project ,we are using webrtc to connect two mobile clients in android.
We are using socket signaling to exchange data between two mobile clients.
We were able to connect peer to peer audio and video call in android mobile clients in same and different network.
Now we changed socket signaling to verto module signalling of freeswitch so that we can make pstn call using webrtc.
After using verto module of freeswitch as signaling,we are able to make pstn call successfully.
Now when trying for peer to peer call using verto module,we are able to successfully exchange media between two verto android mobile clients.
We are able to hear audio flow between two android mobile clients when they are present in same network.
But we are not able to hear audio when two android mobile clients are in different network.
Only observation from logs is ice candidate failed in negative case scenario.
We are using same stun and turn server for app to app call in same network too.

Changed my stun and turn servers too.
But still same problem.

I was sharing my sdp to sip trunk immeditely once sdp got generated which did not contain ice candidates gathered.so i waited to 2-5 seconds and forwarded my sdp which contained sdp with ice candidates and audio started flowing.
Did the same while answering the calls in verto.answer.gave 2 seconds delay to reply so i can send verto.answer with sdp which contained ice candidates gathered.

WebRTC Answer SDP returns recvonly instead of sendrecv

I have a web based WebRTC client and I am having the following functionality:
Step 1. CreateOffer with both audio and video tracks set to sendrecv.
Step 2. Receive and Answer with both audio and video tracks set to
sendrecv. Peer to Peer A/V calls get established here.
Step 3.
Receive a Re-Invite with "a=group:BUNDLE 0 1 video_1". Here I am
getting second video track (video_1)with a=sendonly.

I am creating a new peer connection on getting the Re-Invite, but using the same localstreams object which I fetched during the time of creating the offer in Step 1.
Clearing the existing local tracks from the old peer connection before creating a new peerconnection.
localStream.getTracks().forEach(function(track) {
var sender = call.peerConnection.getSenders().find ? call.peerConnection.getSenders().find(function(s) {
return s.track === track;
}) : null;
if (sender) {
call.peerConnection.removeTrack(sender);
On creating a new peerConnection adding the local tracks like:
newStream.getTracks().forEach(function(track) {
wsclogger.debug("addLocalStream, calling addTrack() --> "+ track.kind);
peerConnection.addTrack(track, newStream);
});
Here I have confirmed from the log above that both Audio and Video tracks are getting added to the newly created peerConnection object.
Please guide me whats going wrong here.
PS: Same logic works well with Android, where the Re-invite Response sdp contains a=sendrecv for the track-1 and a=recvonly for the track-2.
Thanks in Advance.

Chrome webrtc-internals showing audioLevel as 0 and there is no audio

I am using Kurento for audio-only Webrtc. We have two browser apps from where users can connect and listen. But for one of the app, there is no audio in Chrome. And in other browsers it is working fine. Also, the other app works perfectly fine in Chrome. For the app, for which there is no audio, I checked chrome://webrtc-internals/, I found audioLevel, totalAudioEnergy and [Audio_Level_in_RMS as 0. Which seems like the issue. But I am not able to find the reason why it is 0 as same stream is being audible with non-zero audio attributes.

you are either not using a TURN server or not using the correct credentials -- otherwise you would get candidates with type=relay.
There are some types of networks that require a TURN server.

Multi GPU passthrough failed

My server has 4 PCI slots, their addresses are 0000:04:00.0, 0000:05:00.0, 0000:41:00.0, 0000:42:00.0.
I want to pass 4 GPUs to virtual machines via vfio, each of the VMs has one GPU.
VMs worked fine when I passed 0000:04:00.0 and 0000:05:00.0 to VMs or passed 0000:41:00.0 and 0000:42:00.0 to VMs.
But VMs which used 0000:41:00.0 and 0000:42:00.0 had no output to the screen and I could not ping VM's ip when I passed 0000:04:00, 0000:41:00.0 and 0000:42:00.0 to VMs, but the VM which used 0000:04:00 worked fine.
I got the same result when I passed 0000:05:00, 0000:41:00.0 and 0000:42:00.0 to VMs: VM with 0000:05:00 worked fine and VMs which used 0000:41:00.0 and 0000:42:00.0 hanged.
When I define 0000:04:00.0 and 0000:05:00.0 as group A, 0000:41:00.0 and 0000:42:00.0 as group B, the result is:
VMs work fine When I just pass group A or group B to vms.
Just group A works fine when the gpus that I pass to vms contain group A and B.
In case 2, VMs work fine when I used '-vga cirrus' instead of '-vga none'. But I get code 12 from graphics card in Device Manager of windows 7. And this is not what I want, I just want to use the graphics card in the host, so I should use '-vga none'.
It also worked fine when I remove VGA passthrough or just pass 0000:41:00.1 (the HDMI audio of graphics card) to VM.
I got no error output in qemu monitor.
How can I solve this probem?

And following is the stream object which I get inside 'event' when onaddstream() of PeerConnection object is called:
{"onremovetrack":null,
"onaddtrack":null,
"onended":null,
"ended":false,

It works fine. Video stream gets attached to the source element. However, When I try to call from mobile to browser... (mobile becomes the one to send the offer) I get following offer object on browser from mobile:

And following is the stream object which I get inside 'event' when onaddstream() of PeerConnection object is called:
{"onremovetrack":null,
"onaddtrack":null,
"onended":null,
"ended":false,
"id":"ARDAMS",
"label":"ARDAMS"}
When I attach this to video element of HTML page. It shows nothing but 'half black half white' square.
Both peers are able to send ICE candidates too. They are able to send offer and answer to each other. They attach their local stream to the peer connection object.
What could possibly be wrong with this? Can anyone guide me in this?
Thanks.
