WebRTC video call: Connection established, but no sound and video

[kyberorg]

There is problem with making WebRTC Calls. Connection established, but no sound and video.

Our setup:
Server - CentOS 7.4
Mattermost (4.6) - standalone according Installation manual.
WebRTC (latest) - as docker container.

Mattermost is behind Nginx. WebRTC Gateway has direct connection.

WebRTC deployed with docker-compose:

version: '3'
services:
  webrtc_app:
     image: mattermost/webrtc:latest
     restart: always
     container_name: webrtc
     ports:
         - "7088:7088"
         - "7089:7089"
         - "8188:8188"
         - "8189:8189"
     env_file:
          - ./.env
     extra_hosts:
       - "host:172.101.0.1"
     volumes:
       - "/opt/janus/certs_from_host:/opt/janus/certs"
     networks:
       webrtcnet:
         ipv4_address: 172.101.0.2

networks:

[bdbogjoe]

i have same issue, did you find solution ?

[kyberorg]

@bdbogjoe only workaround currently. We installed janus server from sources to separate debian server and nginx as SSL handler behind janus. This made things working, but not really stable.

[bdbogjoe]

not related to NAT ?
maybe we need to use nat_1_1_mapping property in janus.cfg

[kyberorg]

Not related. Both clients was without or with transparent NAT.

[bdbogjoe]

still does not work from my side, call is starting and after i can see this error in docker log :

what is ICE ?

Hello! I have the same issue with some differencies.
I am using dockers with these settings:
`version: "2"

services:
webrtc:
image: mattermost/webrtc
container_name: mattermost-webrtc
restart: unless-stopped
ports:
- "7088:7088"
- "7089:7089"
- "8188:8188"
- "8189:8189"

messaging:
image: mattermost/platform:4.9
container_name: mattermost
restart: unless-stopped
ports:
- "8065:8065"
volumes:
- /home/ubuntu/webrtc/mattermost/app/config:/mattermost/config:rw
- /home/ubuntu/webrtc/mattermost/app/data:/mattermost/data:rw
- /home/ubuntu/webrtc/mattermost/app/logs:/mattermost/logs:rw
- /etc/localtime:/etc/localtime:ro
environment:
- MM_USERNAME=mattermost_user
- MM_PASSWORD=xxxxxxxx
- MM_DBNAME=mattermost
links:
- webrtc
`
I started AWS instance with static IP
Over it is a Load Balancer with port routing + SSL
3d level domain.

So from outside we have
https://mydomain:443 -> http://instance:8065 (Mattermost)
wss://mydomain:8189 -> http://instance:8188 (WebSocket Janus WebRTC)
https://mydomain:7089/admin -> http://instance:7088 (http Janus WebRTC)

I opened all ports to load balancer and aws instance.

I can download index.html from Janus WebRTC docker using wget https://mydomain

First of all - with the latest build of mattermost (4.10) I did not find “User” -> Accaunt Settings -> “Advanced Settings” -> “Preview pre-release features” -> Enable the ability to make and receive one-on-one WebRTC calls

Buttos (WebRTC) and Video Calls were on their places.

Is it a feature or a forgotten bug? =))

Nevermid, I rolled back to MM 4.9

Other settings (like STUN URI (stun:stun.l.google.com:19302), Gateway Admin Secret (janusoverlord), Enable Insecure Outgoing Connections (true)) are still previous

I can call to another user via Mattermost (Mattermonstr!)
I can agree to let access to mic/webcam from both abonents in browser
Another user can accept call
No any voice/video is recieved
After 10 seconds call is finished, there is a sign: Call with user ended

At that time I can see a Janus log:
[ERR] [transports/janus_http.c:janus_http_admin_handler:1563] Invalid url /

Still have no any video/audio connection…

What is “Invalid url /” ?

inside Janus Docker I found janus.cfg file
There is a [nat] section
“In case you’re deploying Janus on a server which is configured with a 1:1 NAT (e.g., Amazon EC2), you might want to also specify the public address of the machine using the setting below.”

So i made a correction nat_1_1_mapping = ...
*** - is static ip of AWS Instance.

Do not know howto restart Janus server and just restart docker with it inside.

Nothing changed…

Please, help!

I am having the same problem. Anyone find a fix yet?
Using AWS with mattermost-webrtc image and google's STUN. Got connection, but no video or audio. Server outputs: [WARN] [8463656418742744] Missing valid SRTP session (packet arrived too early?), skipping... four times.
