Screenshare broadcasts system-wide audio, not just that of the application.

[bobismymom]

Describe the bug

When streaming any application using Vesktop, audio from other applications is being picked up and broadcasted.

Expected behavior

Vesktop streaming only the audio of the application I selected to screenshare.

Desktop (please complete the following information):

• OS/Distro: Windows 10 LTSC 21H2

Additional Context

I tried streaming VLC, Foobar2000, a variety of games and the issue persists.

yes this is intended

i don't think it's possible to stream just one window with electron api

[PolisanTheEasyNick]

Indeed, using electron API we can stream either all sound from Windows system or sound from one tab:

For now, we are setting audio parameter just to loopback:

that api has no option to choose a custom window. WebFrameMain refers to an electron frame, aka a frame of your own app. not other apps

Ohh, I see now. Anyway there's no way to choose another sound source :(

That is, did I understand correctly that this cannot be fixed?

[Communified]

I love this program, but this being an "intended" feature is almost dealbreaking for the app; I can no longer stream in vc with audio without them being able hear all other sources of audio, INCLUDING themselves in the vc; which makes audio completely pointless. If there's truly no fix due to the api, it sounds like the api needs to be different for an issue as major as this; everything else functions as intended and how I'd expect within native discord. In discord, even desktop audio capture does NOT include discord; meaning you hear everything EXCEPT others voices, which is much more acceptable. From what you said does that mean it's impossible to fix even via a plugin strictly due to what the program is built off?

Ope yeah I didnt see this one, didn't show up when I searched, sorry peeps, it's kinda annoying, and yes I wish there was a fix, but if ya can't fix it, that's all good. Hope there becomes a fix in the future! ❤

I maybe have a solution (for windows) tho it's not optimal but what if we set the output of a window to a virtual audio cable¹, loopback the audio¹ and use the virtual microphone for the stream.

1.Can be done within windows settings

I had a go looking at this, commit 4db9f25. Did you mean something like this?

I'm not really good at coding but from what I understand that what I mean.
