ImageData isn't part of the test environment used by Jest. You can create a mock definition for ImageData yourself. You can use the setupTestFrameworkScriptFile setting to point to a file that executes before all of your tests run as described in this answer.

For example, if you need window.ImageData to be available on the window add this to your package.json:

Looks like a Node.js error, I'd suggest updating Node.js to the LTS release.

This is similar to saying that you can use HTML5 to build websites but still people pay AWS to host machines, databases, storage, application logic, etc.

WebRTC is a web technology that is part of HTML5 and is implemented by all modern browser. To make it work, you will need to create websites, install servers, pay for media traffic, optimize your code - you can do it on your own (and pay the cloud hosting vendors for their service) or you can use a third party that offers that as a managed service for you - like Agora and others that do it, where you end up paying to them for their efforts.

To decide which approach is for you, I can suggest two things:

1. Build a simple demo app with WebRTC. One where you understand what the code does. If you are happy with it and truly understand what goes on - make the decision if you want to continue in that route or use a 3rd party
2. Just go use Agora or other 3rd parties and pay them. WebRTC isn't rocket science but it isn't simple either

When you fork, you are creating a process that is an exact copy of the current process. It also copies data so you have access to the exact same things you have on the main process except the pid (the return of the call to fork()).

So your x value is copied. If you change it in the child process it will not be changed in the parent process even if you are using global variables

A 400 response from stop means your original request for start was properly formatted and successfully making the call to start the Agora Cloud Recorder instance but something caused the Agora Cloud Recorder worker to fail to start, so when you call stop there is nothing to stop because nothing actually started.

Have you tried using the Agora Postman collection to test? I would recommend using it within Postman because it offers a working config that requires you to set your connection credentials into the variables and it should work if your bucket is properly configured.

I wrote this quick-start guide on how to set up Cloud Recording and use the Postman collection to test that your storage bucket is properly configured.

The enableLogUpload method is used to send logs to the Agora Server to debug potential problems, if you want to maintain the application logs for yourself you can use a different service like datadog

Cloning of the repository fails, but, the .unitypackage seems to work even in 2020.3 version of unity and macOS dev env. The package is available here: https://github.com/AgoraIO-Community/Agora-Unity-RTM-SDK/releases . Just double click and import. It produces some GUID errors, so please comment if someone has fixed these GUID conflict issues.

It can be done via firebase push notifications & backend API service.

Sender side:

As soon as a call is made, you would post your backend api service with caller and receiver id, and your backend service is further responsible to send a push notification with a payload to the receiver.

Receiver side:

When receiver gets a push notification, you can configure it to open your app automatically and show a screen with all the payload information. Maybe you can show him a screen with accept and decline button and if he accepts, you can connect him to Agora.

Check this for payload configuration.

I did try something like this recently, will share my insights.
Some points about WhatsApp call in the latest android versions:

1. Only when the phone is locked you will get a full-screen call notification
2. For other cases you will get a notification with accept or reject buttons

So the main thing you would need is a message transfer method, for which you could use firebase_messaging package.

For notifying the user you could use awesome_notifications package
