Enable WebRTC for Web App

[Cryptuser11]

Hello, I am creating a QML Web application which must use webRTC but I learned that it had been disabled in the Morph browser in recent versions:

This is a very good reason because it prevents IP leaks.

But I need it for my application which is confined only even by adding flag parameters to the WebEngine:

--enable-webrtc-hw-vp8-encoding --use-fake-ui-for-media-stream --enable -media-stream

It still does not work. How to solve this problem ?

Please, can you give me a link of this info ? Thank you

As far as I know, what causes IP leaks is webRTC connections with public IPs. This is how to enable it on the QtWebEngine, If you aren't using a VPN you shouldn't care about the leaks.

import QtWebEngine 1.11
import QtQuick 2.12

WebEngineView {
    settings.webRTCPublicInterfacesOnly: true
}

from my unreleased browser

@domubpkm For you https://github.com/ubports/morph-browser/issues/257

@ikoz It didn't work, and I even built your octobrowser application on my phone and the webrtc doesn't work (also tested on browserleak).

How then to enable webRTC in QTwebengine?

@Cryptuser11 On my device both checks have a green mark on webrtc support detection from browserleaks, doesn't that mean it works?

[Cryptuser11]

@ikoz No WebRTC is disabled, because otherwise even with a VPN your IP would be leaked.
So Imy App is pretty simple, I created a web view of https://pairdrop.net to transfer files locally.

It works only in the simulator with clickable desktop but not when the application is installed on my Ubuntu touch... You can test it with pairdrop.net

@Cryptuser11 I am able to use this webapp to share text between android and ubuntu touch. I don't see the problem.

[domubpkm]

@Cryptuser11 Yes, i know that because i had opened the issue. The good link now is https://gitlab.com/ubports/development/core/morph-browser/-/issues/257 . However, the issue is always opened. Are you sure there is no WebRTC link currently in focal OTA-5 ?

[Cryptuser11]

@domubpkm Bro, WebRTC is disabled in morph browser you can test in your side with browserleak,and I can not share file with pairdrop.net in my Android devices!
I would find any solution to fix that because in the clickable simulator it's work fine but not in UT;)

[Cryptuser11]

@ikoz Can you explain your environment and your setup? Test share files between your Android or computer with UT in pairdrop.net

[ikoz]

@Cryptuser11 My setup is a phone with ubuntu touch 20.04 on latest RC, all browsers work (including morph) and an android device with firefox. I can succesfully pair devices, send text and share an image. What is your setup?

[Cryptuser11]

@ikoz Okey very strange on my Ubuntu touch he not work, can you test my app and say me if work? The app: https://open-store.io/app/pairdrop.lucstay11

[ikoz]

@Cryptuser11 It works on the app as well. What devices are you testing it on?

[Cryptuser11]

@ikoz It's my Phone the problem I think (Redmi note 9 pro)
