[Galene] Re: Recording in v0.61

[Jeroen van Veen <jvanveen@protonmail.com>]

You can add audio to the screenshare stream (at least in Chrome-based browsers) by using 
audio: true in getDisplayMedia (https://developer.mozilla.org/en-US/docs/Web/API/Screen_Capture_API/Using_Screen_Capture#capturing_shared_audio).
Then you would only need to download that particular recorded stream. Another nice tool for stitching 
multiple streams together is ffmpeg. Haven't tried it myself, but here is an (old) example: https://trac.ffmpeg.org/wiki/Create%20a%20mosaic%20out%20of%20several%20input%20videos

kind regards,

Jeroen
