I want to record two live video streams (rtmp flash videos in a browser) at the same time and I'm running two instances of the SimpleScreenRecorder for that. Each instance records a different region on the screen. The only problem is sound. I use separate browsers so each browser has its own audio playback in pulseaudio.
How can I separate playbacks so that each playback stream will have a separate pulseaudio monitor? I have only "Monitor of Built-In Audio Analog Stereo", but I need two monitors, one for Firefox and one for Chrome.

I have done it using Jack audio server :
mkdir ~/.pulse
echo autospawn=no > ~/.pulse/client.conf
pulseaudio -k
(Later, to revert to pulseaudio normal mode, run
echo autospawn=yes > ~/.pulse/client.conf
thenpulseaudio
)Run qjackctl from sound menu, click "start", click "connect" to display "connections" windows.
Launch 2 differents SimpleScreenRecorder , chose "jack" as audio , start preview mode to display vumeter in both
May be Firefox has problem with html5 and jack audio server in youtube, I have only tested with flashplayer.![qjackctl](https://i.stack.imgur.com/U5LQe.png)
