Download Screen capture + Audio in HTML5 build

Hi, I have an animation game.
(It’s basically a fight game, that uses remote triggers to produce an animation)

So now I’m at the point where I’d like to have a way to capture the screen and the audio produced, and be able to download it.

I have tried recordRTC and applied it in HTML to record the canvas while it’s playing. Only problem is that it doesn’t record the audio. (Actually tried very different approaches with the audio, but it only fetches the mic or mp3)…

So I’m now hoping that something within Defold engine can help me.

Anyone got any ideas to try?
(Doesn’t matter if I have to do it from the HTML5 output and fetch the stream… or do it from the game it self…(somehow)…

Thanks and cheers!
