Simple example for WebRTC on iOS written in swift5

SimpleWebRTCExample

This is simple WebRTC Exmaple project for iOS written in Swift.

Feature

• Super simple WebRTC example project written in Swift.
• Example command lines to build WebRTC.framework.here
• Includes prebuild WebRTC.framework here. (This is for TEST ONLY.) THIS IS REMOVED.
• Datachannel implementation (text and bytes).
• File Source implementation.
• Camera position switching(tap local camera view.)
• Includes super simple signaling server written in node.js.

Dependency

• Xcode version 10.3
• Swift version 5
• GoogleWebRTC
• Starscream (for websocket)

Setup

• You need to add WebRTC.framework to your xcode project. see how_to_add If you want to build WebRTC.framework and use it, see how_to_add. Currently, this project uses GoogleWebRTC installed via pod.
• pod install
• You need to setup signaling server.
  This project includes simple one at SimpleWebRTCExample_iOS/SignalingServer/.
  You can setup node.js as folows.
  • cd SimpleWebRTCExample_iOS/SignalingServer
  • npm install

Usage

• Firstly, run the signaling server as folows.
  • cd SimpleWebRTCExample_iOS/SignalingServer
  • node server.js node.js server will start at 8080 port.
• Change signaling server url ( the ipAddress String vallue) to your case in ViewController.swift. You can find your signaling server url in signaling server log.
• Then, run SinmpleWebRTC on your device or simulator. This example need totaly two devices(simulator & simulator is OK)
• Check websocket connection state on your device. If it is connected, you can tap call button. WebRTC will be connected.
• You can send like with like button. You can send plain messages with message button.
• Enjoy.

Can you give me any advice on implementing webrtc on macos?

Hi~

I think this is a good project for ios webrtc development.

I want to implement webrtc on osx platform.

Can you give me any advice for implementing webrtc in osx?

Thank you.

Hello ! Thanks for your project, little questions here !

Hello,

First of all thanks a lot for your project ! It helped us a lot, we are touching WebRTC for the first time !
But I have some questions, we actually have a drone (DJI Spark) and we have a Data (Array Buffer) variable.

We have the websocket server, and we actually did a call with your source code. 🔥

So we have something like this

func videoFeed(_ videoFeed: DJIVideoFeed, didUpdateVideoData videoData: Data) {
        if !webRTCClient.isConnected {
            webRTCClient.connect(onSuccess: { (offerSDP: RTCSessionDescription) -> Void in
                self.sendSDP(sessionDescription: offerSDP)
            })
        }

        videoData.withUnsafeBytes { (bytes:UnsafePointer<UInt8>) in
           videoPreview?.push(UnsafeMutablePointer(mutating: bytes), length: Int32(videoData.count))
        }
}

But during the init of WebRTC, You are doing the creation of videoPreview with setupDataChannel. How can I change this to my videoData my videoSource with another source ?

Arigato gozaimasu !

Won't allow me to add WebRTC.framework

I have no idea but I am following your way but it wont allow me to add WebRTC.framwork. Obviously its the simple thing but no success.

using swift 5 & Xcode 11.3 (recently updated to) Mac OS Catalina

Authentication

Hi - thank you so much for sharing your hard work. This has helped me so much.

Do you know I could add in a simple password option so both people need to know a simple password before they are able to join?

Thanks

I am using broadcast upload extension for screen sharing which is working fine but i also want to send audio buffer to webrtc but seems like there is no direct way of doing that can you help??

Server side websocket is not connected

Thanks for the good work. In local host worked perfectly. But i tried to move live server websocket is not connected. So please guide me the installation from server.

Is it possible to group Call with your demo?

can this example run multiples devices at once ?

Hi , thank you for this project it saved me a lot of time,
i'm trying to run the example on 3 iphones to make a streaming but there only 2 that can communicate at the same time, can we make an update to make it like a chat room where they all connect to the same room to chat ?
if you just can confirm me and just give me an idea i'm still reading and trying to understand the code and how the whole application is working.
Best regards

Mix call audio with locally playing video

The more I look through your code and the project the more I love it!

Quick question - is it possible to mix the audio of the caller with a locally playing video (AVPlayer)?

Thanks again

By using "GoogleWebRTC", How can we avoid NOISE SUPRESSION and ECHO CANCELLATION

Hello,

Android Platform used following stuff to avoid Noise Suppression

---

WebRtcAudioUtils.setWebRtcBasedAcousticEchoCanceler(true);

Error executing: gn gen out/ios_64....

Excellent instructions to generate WebRTC framework... thanks! I am trying to build the framework on a iMac with OS: 10.15.4 (I think is beta 4) and Xcode 11.4 (released)... I am very unfamiliar with the google tools and I hope to not have to learn; I prefer to be able to build my own framework.

after downloading m79 and "sync -D" I am trying to generate the 64 bit version and I get the following error:

Add example of peers client

Currently, this project can only establish peer to peer connection.
And, there are some question that how to establish multiple connection. #30 #29 #27 ...

So, I created peers to handle multiple connection(signaling) for WebRTC full-mesh topology (you can try multiple connection here).

I will add peers-ios example in this project. Then everyone can play with multiple connection, I think :)
