Unity web view, Jitsi, IOS

[problem]

In AOS the launch in web button is enabled and in IOS there is no button.
Is there any solution?

saghul · March 14, 2023, 10:37am

What type of WebView is that?

dnddkqjayou · March 14, 2023, 11:48pm

I’m not sure what type it is.
I am using vuplex’s webview asset.

saghul · March 15, 2023, 6:33pm

And does that have WebRTC support?

dnddkqjayou · March 16, 2023, 12:04am

Yes this works flawlessly on android.

damencho · March 16, 2023, 2:08am

And which iOS is this, should be 14.3 or newer?

dnddkqjayou · March 16, 2023, 4:21am

Tested on the latest version of ios.
What does the 14.3 version mean?

saghul · March 16, 2023, 10:31am

The Android and iOS implementations are completely different so whatever happens on Android doesn’t apply to iOS.

dnddkqjayou · March 16, 2023, 11:51pm

Thanks. I understand.
I asked the same question to the vuplex company that made the webview, but the solution to the problem was up to jitsi.
What should I do next?

damencho · March 17, 2023, 12:10am

Does this work for you getUserMedia ?

BJ-Kim · March 17, 2023, 2:49am

in my opinion, to use vuplex’s webview
you need to check this function’s return value

github.com

jitsi/lib-jitsi-meet/blob/master/modules/browser/BrowserCapabilities.js#L105


      
           */
          isTwa() {
              return 'matchMedia' in window && window.matchMedia('(display-mode:standalone)').matches;
          }
          
          
/**
           * Checks if the current browser is supported.
           *
           * @returns {boolean} true if the browser is supported, false otherwise.
           */
          isSupported() {
              if (this.isSafari() && this._getSafariVersion() < MIN_REQUIRED_SAFARI_VERSION) {
                  return false;
              }
          
          
    return (this.isChromiumBased() && this._getChromiumBasedVersion() >= MIN_REQUIRED_CHROME_VERSION)
                  || this.isFirefox()
                  || this.isReactNative()
                  || this.isWebKitBased();
          }

It doesn’t work.
Does this have anything to do with it?

dnddkqjayou · March 17, 2023, 5:30am

I am using the latest version of ios,
Since the user agent was not safari, it was forcibly fixed to safari.
However, this problem still occurs.

Incidentally,
Jitsi does not work in the webview of the ios built app
It works in safari on iPhone.

BJ-Kim · March 17, 2023, 6:41am

umm… i think this you need to this function’s value
this function check somethings to use webRTC basic object

    /**

               *

               */
              _getIOSVersion() {
                  if (this.isWebKitBased()) {
                      return Number.parseInt(this.getVersion(), 10);
                  }
          
          
        return -1;

If the basic webrtc test above is not working with that browser, there is no point of trying any further steps.

dnddkqjayou · March 20, 2023, 6:40am

You mean it’s not a problem to be solved in Unity, but we need to fix that part in jitsi?

BJ-Kim · March 20, 2023, 7:26am

you need to check vuplex’s webview spec to it is support webrtc or not.

dnddkqjayou · March 20, 2023, 7:41am

support.
It works fine on Android.

BJ-Kim · March 20, 2023, 7:59am

as i know, chromium’s spec is different between on ios and android.
so, i think vuplex webview also same.

you need to check on ios

dnddkqjayou · March 20, 2023, 8:39am

Thank you. I will leave more comments after checking.
