QUESTION

WebRTC is failing to connect after ice candidates have been added

Asked 2022-Apr-18 at 00:36

I am making a local network chat app in JavaScript, and I am able to connect between two tabs on any single computer, but when I try to connect two computers (on the same wifi network) it fails.

What works: Two tabs on the same computer (even if different browser, ex. chrome tab<->firefox tab).

What doesn't work: Two different computers (ex. laptop<->desktop), even on same network (if one of the devices is the host of the page).

I have tried to get information from chrome://webrtc-internals/, and this seems to be the only major difference, (when it works, the numbers separated by slashes match). (this is the ice candidate grid for the failing case vv)

Because the client and server are not on the same machine, when you access the media from a browser, for security reasons you must install an SSL certificate on your server.

How to setup Jitsi Meet on a custom Kubernetes

Asked 2022-Mar-25 at 04:50

We have a single node kubernetes environment hosted on an on prem server and we are attempting to host jitsi on it as a single pod. Jitsi web, jicofo, jvb and the prosody will be in on one pod rather than having separate pods for each (reference here)

So far what we have managed to set it up by adding our ingress hostname to as the PUBLIC_URL to all 4 containers within the pod. This service works fine if two users are on the same network.

If a user using another network joins the call, there is no video or audio and will receive such an error in the jvb container

Managed to fix it. Posting this for anyone who comes across the same issue.

first off the UDP port 10000 does not work in kubernetes as you can only expose ports between 30000 to 32768. Having said that you need to pick a port within that range and use it for the JVB_PORT configuration in the JVB container.

secondly use that port in the service lay to expose it to the front end

ANSWER

Answered 2022-Jan-31 at 16:53

I think you're confused about Live Streaming and Video Chat, which are both very important but different video platforms and use scenarios, and their architecture is totally different.

I think TIKTOK is an mobile app with:

Most of it is VoD file and social connections.
Some part is Live Streaming, like twitch.tv or YouTube live streaming.
Few of Video Chat ability, only when two user are talking in a RTC room.

For VoD, it's something like HTTP(S) files, deliver by CDN or Nginx if you want to build it.

About the Live Streaming and Video Chat, please read detail from here.

As you can see in the following screenshots this is not infinite either:

first row with "We are trusted by over 28,000..." and second row

It's just that on normal screen you can't reach the end of the element.

You can accomplish something similar by adding an listener on scroll and transforming the element you want to be moved retative to window.pageYOffset value.

Webrtc video streaming working properly in localhost but not working in production (using google turn server)

In local server, video streaming is running proper on both ends but while network changed video of one peer is not going to display to other peer.

I am not able to understand what I am doing wrong here.I am novice in webrtc

Answered 2022-Jan-12 at 06:27

as you move out side of the network the webrtc ICE candidate gathering process may fail because of Routers NAT and firewalls therefore you must have a turn server in your configuration that will relay the traffic if the direct p2p connection establishment fails

QUESTION

WebRTC: do we need a TURN server if one peer is always using Full Cone Or Address Restricted (but not Port Restricted) NAT?

Asked 2022-Jan-07 at 14:56

I have been reading a bit about WebRTC, and I'm not getting why we need a Turn Server if only 1 peer is using Symmetric NAT, and the other is using neither Symmetric nor Port Restricted NAT, so let’s say A is using Full Cone NAT, B is using Symmetric NAT:

STUN SERVER will send the correct IP address of B to A, and the correct IP + Port address of A to B.
A tries to connect to B (now A will be able to accept messages from B since it’s in the Dest Address Column).
B tries to connect to A, which will allow requests from A going to B (ofc A needs to update the port to the one received from B instead of the Sdp).

am I missing something, or is this correct (and implemented), or is this too complicated to be implemented?

And if this is correct, then theoretically, if I’m peer A and I'm using Full Cone NAT, any peer B can connect to me (as long as I send the connection request first), without needing a TURN server.

Thanks

ANSWER

Answered 2021-Aug-01 at 18:09

If the symmetric NAT environment only changes the port, you would be correct with regarding connectivity to Full Cone NAT. The hole punching step would work.

But many enterprise and mobile environments have complex routing schemes and crazy network environments that are different from a legacy home network router. These environments aren't just a little router box that hooks up to a cable modem. It's a complex array of routers and load balancers using a bank of IP addresses. And each outbound connection might get an IP address different from a previous connection. So it's technically "symmetric NAT".

And so after a node within this environment obtains an external IP/port pair from a STUN server, subsequent sends to a peer address might change both both the port and the IP address as well.

As such, the NATs see completely different IP addresses than expected when the UDP packets arrive during the hole punching step. Hence, a relay address (TURN) is needed here.

ANSWER

Answered 2021-Dec-22 at 10:15

Disclaimer: I never used pyejabberd, so I'll just give you some ideas to investigate.

I see your client attempts to connect to port 5443 with HTTP protocol. Looking at your ejabberd configuration, that has TLS enabled... so maybe it should be HTTPS? Or you can try to set "tls: false" in ejabberd.

Also, what kind of connection method does pyejabberd use to connect to ejabberd? XMPP (port 5222), or XMPP over BOSH (port 5443), or XMPP over WebSocket (port 5443, but a different URL path).

Maybe you should set in pyejabberd port 5222 and protocol xmpp, or something like that.

Check in ejabberd log files, if it receives the connection attempt. Try to login with a well-known XMPP client, so you learn how that looks in ejabberd log files (what messages it shows when login is successful), and compare that with your client.
