Whats up everybody? WebRTC has been a really fun technology to play around with and make videos about. To that end, what are some webRTC videos you all would like to see me work on?
Would be amazing to see how to implement this so it works on iOS devices. Built an entire video chat app, just to find out that iOS devices didn't like it...
Hey thanks a lot! I must say, I love that you leave gaps in the code to fill. It really made me understand what's happening and also brought me into react. Great stuff!
Great content youre putting out there I subbed immediately. I have one question tho, does the simple-peer abstraction come with a default STUN/TURN server? Say im trying to make a p2p connection between two devices both sitting behind firewalls, would it work without the need to manually configure a STUN/TURN server?
@@CodingWithChaim you know, there are a lot of tutorials about MERN( or even with typescrypt), but all of them are simple and similar to each other. It is difficault to find course with project written in the processional way (production code), with such features like advanced filters for e-shop, payment system, advanced animation, audio/video steams, advanced react hooks. We need a project for our future interview (if it is possible)) thank you in advance)
@@pavel1429 So it took me a while to come up with an idea for this video idea, but I think I have one. I think I might be able to have it live in 2 weeks time!
Hi Chaim, great tutorial! Thanks very much. For some reason I cannot see the call id button on screen when I start another tab. I have a feeling that my browser is recognising all the tabs as one user? Tried different browsers but same issue. Any ideas?
Thanks for this! Im going to build a video chat app with another features all in firebase eviorment, do you think that next.js (ssr) would be a better option for this?
you are very welcome. I think in this case there is no real reason to choose one over the other. Typically the considerations that are taken into account when choosing ssr or otherwise, are things like SEO or performance, but in this case neither are really a concern. I guess my point is, for the sake of the actual video chat, either approach is fine. If you have other considerations for your specific use case, then thats what you should look at to decide which way to go.
Thank you for these great contents on webRTC. would you please explain a little more about STUN server and signaling server that have been used in this project? Unfortunately I don't know how to implement STUN and signaling server for simple-peer library.
Very impressive explanation, Chaim. One question, I have is that in your github code, your callPeer function defines a config object, with an iceServers array, that has credentials for TURN and STUN. However, you did not show this in the video. Does one still need to define the config object?
For a simple local app just to mess around with you don't NEED those and at the time of recording I had not included those. A few months after the video came out I a PR from a viewer to include those and I merged it. I would say, if you wanna make a video chat production ready you would need a TURN and STUN server, but at the same time I would not rely on the those provided in this code example.
I am looking for webRTC between smartphones and PC webs. The simple-peer seems to support only browsers for PC webs. I wonder if you have any other sample for them which is between phones and pc webs?
Hi, can you make tutorial how to share screen on group video conference with reactjs and nodejs, would be awsome if you make tutorial how to make full video conference app with react js and node js, thankyou chaim
Hi Chan please I am quite a newbie here, how do I make the user to be called dynamic like loading the user state in a react component and then using the user ID into the call... like user-1 calling user-N thanks
I am not entirely sure if I fully understand your question, but I think watching my other webrtc vide chat app might help you. In that video I demonstrate the concept of actually calling a user. Here is the link: ua-cam.com/video/BpN6ZwFjbCY/v-deo.html
I actually have a video idea where I will be building a video chat app using webrtc without simple peer from scratch. Look out for that in the next 3 weeks or so
Hi. Great video! I'm trying to add WebRTC to React native and I don't think I'll be able to use simple-peer. Do you have any examples with RTCPeerConnection?
Hi! Glad you enjoyed the video! At the moment I dont have any examples without simple-peer, but I did find this gihub issue which may be of interest to you. github.com/feross/simple-peer/issues/109
Hi Chalm, Great video, I can make it work on chrome and both tabs are handshaking correctly. however, when I run it on Mozilla the first initiator does not seem to get back the stream from other users who has joined, and all others user who has joined can receive the stream of previous users. Not sure what's causing this to happen or if you have any idea what's causing this? thank you
Hey. First of all, great video! This helped a lot! Next, this might be an easy fix but I'm new to this. Here is an example: A video chat room is filled with people that are streaming their camera, now an admin wants to join that room and without showing his camera but he wants to see what the other users are doing aka wants to see their faces. How would you do this?
I think the simplest way I can think of doing is would be for you do add the admin to the room using the mesh network approach. You can see this in my group chat video. The difference here would be that the admin won’t be sharing and voice or video, so the others won’t see the admin or hear the admin. I would highly suggest watching the group video because that will show you how to have more than 2 peers connected at the same time
Should I need to do anything extra to deploy this to heroku? It's working fine locally but I get a polling-xhr timed out error when accessing it in heroku. I've added a procfile with a command to run the express server. And have done the same in package.json in the react scripts start command. Would you know whether Heroku works with paths from the root or does it just look into the src folder? Just in case I have the paths wrong.
Hey Chaim, your videos are great. Extremely helpful. But if you can speak a bit slower, that will be better for us viewers to comprehend and follow. Cheers!
Hello, can i set socket id for each user so it doesnt generate a random one when ever they connect for exemple i set on each user my database socket_id column
Step 01: create a real-time chat (using socket.io) and video&audio stream (using webRTC and socket.io) Step 02: make sure to put the real-time chat and video&audio stream in the same room ( socket.join("same room") ) Step 03: render the real-time chat and video&audio stream on the same page that's it best of luck mate.
Hi love your demo here, do you think this mechanism suitable for cases like streaming for education purposes? I'm trying to build an E-Classroom project here
Leon Chow there is something called a selective forwarding unit. I would suggest you start researching that. Unfortunately I’m still too unclear on the topic to really help. You can look into something called mediaSoup that is an open source module to solve this problem.
Hi nice video but I have doubt if u open in 3 tabs and calling 2 user to a same user ? So how can I reject a call or simple single request accept. I have to implement peer to peer
Hi, thanks for this video, was super useful! One issue I'm having is that the audio isn't working - you hear a screeching sound as soon as you accept a call. Have you encountered this issue before?
it depends on what technology you use in your dating app. let's say if you used React and Express in your existing dating app then implementing the video/audio call can be easily done by just following Chaim's video tutorial. but if you used different technology I suggest checking out the documentation on how to apply webRTC on it. the process of implementing webRTC in another tech would probably be the same so watching this video will certainly help you implement video/audio call in your app. best of luck mate.
Question, if I wanted to build something like where 2 people video call, but ALSO let any arbitrary number of people stream the video call without participating, how would I implement that? Thanks
Dav 1243 this would require some sort of peer to server setup. You may want to look into webrtc ingestion servers and media servers. The idea is you would send the stream to the server and the server would then distribute the stream out
Hey Chaim , thank you for the tutorial, however i want to ask , is it possible and reliable to create a rooms video conference web app (more than 40 users per room) absed on webrtc, thank you again
My pleasure! Yes it is possible, I actually have a video which discusses this, but in my video I use a technique called a mesh network which only allows for 4 to 6 users give or take. Making a group video chat with more than 40 users requires some more complex solutions which I am still researching. Hopefully I can have a video about that in the nearish future. Here is the group video chat video using mesh network ua-cam.com/video/R1sfHPwEH7A/v-deo.html
SignalR, if I understand correctly, is more of a websocket framework in the dotnet world. Websockets are not the correct tool to use for video chat. In this video I am using socket io only to facilitate the handshake between the peers, but the actual video chat is happening via webrtc. I would be happy to do a video with signalR at some point in the future, but I would like to be more clear in what your request is.
@@CodingWithChaim I am just curious to know how to integrate the backend Signalr Asp.net core to manage connections between users doing video chatting.
No so much a part 1 per se, but I do have a video about socket io specifically. Here is the link to this video: ua-cam.com/video/E4V6nbP_NoQ/v-deo.html
@@murderousvortex that's a react issue. you're trying to render a component dynamically and one of the requirements in rendering component dynamically in react is to put a unique key. e.i. ArrayOfButtons.map( item => ( {item} ))
Does anyone know if there is a "houseparty" equivalent for a corporate private event? I manage events (physical and virtual) and my clients would benefit from having a networking room. I picture something like a top shot of a room with 'live' dots representing all the registered and connected people, so that a participant can hover and tap on any other participant for a quick 1:1 video chat or round tables of up to 5-6 participants... Is there such a tool out there? Anyone technical want to tell me who could potentially develop it otherwise?
you just need to set that all up in socket.io (server side) in which you just give them rooms. the same concept on how the code in this video tutorial is implemented the only difference is that the roomId is not random and you might want to put some middleware to check if the client is allowed to enter the room to prevent some stranger entering the group/1:1 video call best of luck mate
nice video, I followed all the steps and deployed it to Heroku. It works on my LAN but when I try to call from different devices in different networks I can't get video. Any experience with that?
Getting video might depend more on the actual os/browser combo and whether it supports media devices. If you are actually able to have a proper handshake between the pairs, then its most likely not a network issue, but rather a feature availability issue. As an example, I have not been able to get video on IOS chrome.
Interesting, I was able to make a handshake since the call and answer button work. I have two scenarios both using my app in Heroku. 1. I make a call from two different devices connected to the same wifi network, it works. 2. I make a call from the same two devices but from different networks this time, it doesn't work. Have you tried to deploy this example or any other Webrtc project?
Yea I actually deployed my group video chat app to heroku. It's a buggy mess at this point :) but it does work. Here is a link: groupvideo.herokuapp.com
Nice, as expected I experienced the same problem there. I found a nice explanation here stackoverflow.com/questions/51748284/webrtc-only-works-locally-even-after-deploying-to-heroku leaving it in case someone faces the same problem. Your videos helped me a lot, keep the good work and thanks a lot for your help.
why would you advise people to write trickle: false without figuring out what it does? it stands for ICE trickle, which allows incremental gathering and connectivity checks between the peers. you should always use it
Hi Chaim, nice video, really simple and helpful!! I am trying to use this same strategy to connect the React client (peer) to a Flutter client (peer) in a simple one-on-one connection. I could make the two peers to see each other and receive their ID's, but I don't understand how to manage the signal and how it is related to ICE Candidates which I need to manage from the Flutter end... The Flutter user receives the calling from the React user but then I cannot make the streams to start playing... Can you give me some help or at least tell me once one user called the other how ICE Candidates, Signals and Stream are related and come into play..? Thanks in advanced!!
The simple peer library abstracts the offer, answer and the ice-candidate exchange between peers and puts it all into the signal. If you cannot use, simple peer on the flutter side, you way just want to use the native webrtc api without simple peer. You can see this video on how to use the native webrtc api ua-cam.com/video/JhyY8LdAQHU/v-deo.html
@@CodingWithChaim Woow, thanks!! I mean you just literally published this video today which will really help me to achieve what I need... Perfect sync!!

You need to have 2 terminal tabs/windows open at the same time. 1 should be open to the root of the app and the second should be open to the client folder. In the root, run the command node server.js and in the client folder run yarn/npm start. They need to both be running at the same time

Hello, first I am quite a beginner but need to implement such a setup for a project so I am looking around and try things out! I have the same mistake as Mitchell: I get this error "Proxy error: Could not proxy request /@t from localhost:3000 to localhost:8000. See @t for more information (ECONNRESET). I read that it could be because I did not run the server before hand, However In my Terminal I cannot manage to start both is either one or the other. I have my camera on because when playing on the client npm start it display the camera view. Any idea what I did wrong or how to start both?
You wont be able to start both process in the same terminal window, but you can open one window per process. So either have 2 terminal tabs, or 2 windows. Hope that helps!
I am not getting any error, when i run the program i get the message that the "server is running on port 8000", but on localhost:8000 is says Cannot GET /
While the server is running, you also want to have the client side code running at the same time. In a separate terminal, go the the client folder and run the start command there
Great video man. I hosted server code in herko and client on netlify and it seems to work only when one of the users is using local host and other one is on the netlify website. But when both users are on website it gives this error "*index.js:17 Uncaught Error: [object RTCErrorEvent] at h (index.js:17 at RTCDataChannel._channel.onerror (index.js:490)*" . any clue? I also want to know what extension you use on vsc. And i really hate emojis XD otherwise A+ video man
Thanks for the feedback!! I think you may need to look into including a turn server to get past firewalls issues. The way I have it setup works for dev but in a real project a turn server is needed.

Hello do you think it is easy to make a WHITEBOARD interactive in WEBRTC ? Many user can Write with the mouse many think. ( like teachers and students )
Assuming this would work without video then a simple mesh network would do the trick for something like your idea. If however teacher and students would also have video of each other it gets more complicated
@@CodingWithChaim so it is better to use WEBSOCKET ? I believed "writing in a whiteboard" using canvas and JSON transfert the coord of the mouse of each one and "draw" ?
I think for the sake of sharing the data of what’s on the board both sockets and webrtc are both fine options. The way I see it, choosing between the 2 comes down fo latency. WebRTC is faster so if that it something you need go with that. Again if it’s just for the board and no video then webRTC solution won’t be too complicated
@@CodingWithChaim Thanks for the answer, but I have a couple of questions.

Hey quick question, I downloaded the starter code and ran npm install on both the client and the server. when I try to run npm start on the client I get this error "Proxy error: Could not proxy request /socket.io/?EIO=3&transport=polling&t=N5rmc4h&sid=TOiO0D0_iqgpJda2AAAA from localhost:3000 to localhost:8000. See nodejs.org/api/errors.html#errors_common_system_errors for more information (ECONNRESET). "
My only guess would be that you have the client code running but not the sever code. In the server code you would need to run node server.js so that the client has who to proxy to.
In that case I would say you possibly starter the client before the server which is why you have this error. If both servers are currently running, you should be good to go. Please do let me know if the problem remains.
The other users have to be in the room first to be listed for calling because they're going to be identified by their userID that was created when they visited the url So then how would this work with real users? How do you get them in the room first? Anyone please
In this example, only 2 peers can call each other at any one point in time. You can have many 1 on 1 conversations, but each video chat can only be between 2 people using this example. I have another video where I demonstrate how to make a group video chat. In that example, you can have up to 6 max people in one group chat. Here is the link ua-cam.com/video/R1sfHPwEH7A/v-deo.html
Yes you absolutely can! The only thing that would change in the code would be to not request the browser for the video stream, but only for the audio stream. It would look something like this navigator.mediaDevices.getUserMedia({ audio: true }) In this snippet we are only asking the browser for the audio and not the video. That is the only change needed.
I myself have never tried this, but so far as I can tell there should be no reason why this would not work. If you do try this, please do report back with how it went.
I don't think this will work in with rn tbh. the navigator.mediadevices is something that does not exist for example... you can get it to work, but the code will be pretty different i think.
The way I wrote the code was mostly for demonstration and not fully ironed out. In reality when a call ends, the peers should be cleaned up, and each new call should create a brand new peer. I believe this may be the cause of your issue.
@@CodingWithChaim So both the initiator peer and the other peer must be set again. But isn't that happening by default when acceptCall() function is called.
You need to make sure you have the backend and the client side servers running at the same time. In the root of the app run node server.js and at the same time run npm start in the client folder

Hey. First of all, great video! This helped a lot! Next, this might be an easy fix but I'm new to this.
Here is an example: A video chat room is filled with people that are streaming their camera, now an admin wants to join that room and without showing his camera but he wants to see what the other users are doing aka wants to see their faces.
How would you do this?
I think the simplest way I can think of doing is would be for you do add the admin to the room using the mesh network approach. You can see this in my group chat video. The difference here would be that the admin won’t be sharing and voice or video, so the others won’t see the admin or hear the admin. I would highly suggest watching the group video because that will show you how to have more than 2 peers connected at the same time
@@CodingWithChaim Thanks! That was quick! :O I'll have a look!
Should I need to do anything extra to deploy this to heroku? It's working fine locally but I get a polling-xhr timed out error when accessing it in heroku. I've added a procfile with a command to run the express server. And have done the same in package.json in the react scripts start command. Would you know whether Heroku works with paths from the root or does it just look into the src folder? Just in case I have the paths wrong.

Hello, can i set socket id for each user so it doesnt generate a random one when ever they connect for exemple i set on each user my database socket_id column
IT'S GREAT Please i have question how can i add that other users can chat with text and one with live video like live in youtube any guide please ?
Step 01: create a real-time chat (using socket.io) and video&audio stream (using webRTC and socket.io)
Step 02: make sure to put the real-time chat and video&audio stream in the same room ( socket.join("same room") )
Step 03: render the real-time chat and video&audio stream on the same page
that's it best of luck mate.

webrtc can be used for such a platform, but depending on how many users you are trying to serve you may need to use some sort of peer to server setup.
@@CodingWithChaim maybe would be serving 50 participants per calling session, I got no idea for the server part, any reference?
Leon Chow there is something called a selective forwarding unit. I would suggest you start researching that. Unfortunately I’m still too unclear on the topic to really help. You can look into something called mediaSoup that is an open source module to solve this problem.

Hi nice video but I have doubt if u open in 3 tabs and calling 2 user to a same user ? So how can I reject a call or simple single request accept. I have to implement peer to peer
Hi, thanks for this video, was super useful! One issue I'm having is that the audio isn't working - you hear a screeching sound as soon as you accept a call. Have you encountered this issue before?
Hmm unfortunately I have never had this issue.
Try with headphones. The screeching is feedback from your machines mic/speaker.

Hello there,
I need a video/audio call script to implant to an excisting dating app! are you able with this ?
thanks
it depends on what technology you use in your dating app. let's say if you used React and Express in your existing dating app then implementing the video/audio call can be easily done by just following Chaim's video tutorial. but if you used different technology I suggest checking out the documentation on how to apply webRTC on it. the process of implementing webRTC in another tech would probably be the same so watching this video will certainly help you implement video/audio call in your app.

Hi, thanks for sharing. Is this working outside the local network with according configuration changes?
As long as the app is served over https it should work I believe.

Dav 1243 this would require some sort of peer to server setup. You may want to look into webrtc ingestion servers and media servers. The idea is you would send the stream to the server and the server would then distribute the stream out

My pleasure! Yes it is possible, I actually have a video which discusses this, but in my video I use a technique called a mesh network which only allows for 4 to 6 users give or take.

Hello Friend, can you do Video Chat with SignalR ? I am curious to know how it will work.
SignalR, if I understand correctly, is more of a websocket framework in the dotnet world. Websockets are not the correct tool to use for video chat. In this video I am using socket io only to facilitate the handshake between the peers, but the actual video chat is happening via webrtc. I would be happy to do a video with signalR at some point in the future, but I would like to be more clear in what your request is.
@@CodingWithChaim I am just curious to know how to integrate the backend Signalr Asp.net core to manage connections between users doing video chatting.

Does anyone know if there is a "houseparty" equivalent for a corporate private event? I manage events (physical and virtual) and my clients would benefit from having a networking room. I picture something like a top shot of a room with 'live' dots representing all the registered and connected people, so that a participant can hover and tap on any other participant for a quick 1:1 video chat or round tables of up to 5-6 participants... Is there such a tool out there? Anyone technical want to tell me who could potentially develop it otherwise?
you just need to set that all up in socket.io (server side) in which you just give them rooms. the same concept on how the code in this video tutorial is implemented the only difference is that the roomId is not random and you might want to put some middleware to check if the client is allowed to enter the room to prevent some stranger entering the group/1:1 video call

Thanks it helped me alot but i want to use my local username or user's ID not a random ids is that possible!!!
nice video, I followed all the steps and deployed it to Heroku. It works on my LAN but when I try to call from different devices in different networks I can't get video. Any experience with that?
Getting video might depend more on the actual os/browser combo and whether it supports media devices. If you are actually able to have a proper handshake between the pairs, then its most likely not a network issue, but rather a feature availability issue. As an example, I have not been able to get video on IOS chrome.
Interesting, I was able to make a handshake since the call and answer button work. I have two scenarios both using my app in Heroku.
1. I make a call from two different devices connected to the same wifi network, it works.
2. I make a call from the same two devices but from different networks this time, it doesn't work.
Have you tried to deploy this example or any other Webrtc project?
Yea I actually deployed my group video chat app to heroku. It's a buggy mess at this point :) but it does work. Here is a link: groupvideo.herokuapp.com

Hi Chaim, nice video, really simple and helpful!! I am trying to use this same strategy to connect the React client (peer) to a Flutter client (peer) in a simple one-on-one connection. I could make the two peers to see each other and receive their ID's, but I don't understand how to manage the signal and how it is related to ICE Candidates which I need to manage from the Flutter end... The Flutter user receives the calling from the React user but then I cannot make the streams to start playing... Can you give me some help or at least tell me once one user called the other how ICE Candidates, Signals and Stream are related and come into play..? Thanks in advanced!!
The simple peer library abstracts the offer, answer and the ice-candidate exchange between peers and puts it all into the signal. If you cannot use, simple peer on the flutter side, you way just want to use the native webrtc api without simple peer.

I have the same mistake as Mitchell: I get this error "Proxy error: Could not proxy request /@t from localhost:3000 to localhost:8000.

You wont be able to start both process in the same terminal window, but you can open one window per process. So either have 2 terminal tabs, or 2 windows. Hope that helps!

Hello do you think it is easy to make a WHITEBOARD interactive in WEBRTC ? Many user can Write with the mouse many think. ( like teachers and students )
Assuming this would work without video then a simple mesh network would do the trick for something like your idea. If however teacher and students would also have video of each other it gets more complicated
@@CodingWithChaim so it is better to use WEBSOCKET ?
I believed "writing in a whiteboard" using canvas and JSON transfert the coord of the mouse of each one and "draw" ?
I think for the sake of sharing the data of what’s on the board both sockets and webrtc are both fine options. The way I see it, choosing between the 2 comes down fo latency. WebRTC is faster so if that it something you need go with that. Again if it’s just for the board and no video then webRTC solution won’t be too complicated

My only guess would be that you have the client code running but not the sever code. In the server code you would need to run node server.js so that the client has who to proxy to.
Coding With Chaim that’s strange I do have the server code running as well
In that case I would say you possibly starter the client before the server which is why you have this error. If both servers are currently running, you should be good to go. Please do let me know if the problem remains.

You can look into the addStream and removeStream methods that simple-peer offers.
Hey Chaim, can I do this with only voice and no video? if so, how?
Yes you absolutely can! The only thing that would change in the code would be to not request the browser for the video stream, but only for the audio stream. It would look something like this
navigator.mediaDevices.getUserMedia({ audio: true })
In this snippet we are only asking the browser for the audio and not the video. That is the only change needed.

If I disconnect a call and call again I run into this error. How do I avoid this?
cannot signal after peer is destroyed
The way I wrote the code was mostly for demonstration and not fully ironed out. In reality when a call ends, the peers should be cleaned up, and each new call should create a brand new peer. I believe this may be the cause of your issue.
