Record screen with sound from both other apps and my mic #772

Hi there!

I wonder how to do this thing: I am using online conference software (Google Meet - this is in the browser, Microsoft Team, Zoom - these ones have dedicated software) and I want to record them on my computer. Once in a while, I am presenting and I want to both record my screen and my voice, talking. I have 2 videos like this where my voice is missing (Pulse Audio + Monitor of built in audio analog stereo), how do I get all sounds processed through the computer (in and out) recorded? (this is on Linux/Ubuntu 20.04) PS: since updating to the latest Ubuntu I had some sound problems also, have some clips without sound, cannot figure out why.

Thanks for this wonderful piece of software!

Currently SSR doesn't support this yet however it is on the todo list. There exists a workaround though: https://www.maartenbaert.be/simplescreenrecorder/recording-game-audio/#recording-game-audio-and-microphone-at-the-same-time This approach is a bit unreliable though so I don't really recommend it. It's safer to record your audio separately in e.g. Audacity and synchronize the two later.

Got it. It seems to be both complicated and as you say, maybe unreliable, so not really a solution.

Do you know if sound can be added to mkv without rendering (much bigger files as I record at 5fps and until now I could not find a good solution to render at same filesize and 5fps + time, etc.)? Thanks.

Update: found it, it is possible if they are the same length - https://www.youtube.com/watch?v=1EkhHjn3OEA

You can also use the ffmpeg command-line tool, which is a bit faster than going through the GUI every time: https://superuser.com/questions/1137612/ffmpeg-replace-audio-in-video

@big-tree-wang Would you please stop emailing 'unsubscribe' to random issues please? It doesn't work. I can't unsubscribe you from issues, all I can do is ban you from the entire SSR repository if you keep doing this.

+1 for this feature. My main use case for using SSR is to record video calls when the underlying call system is lacking a record option (e.g. slack video calls on linux).

SSR seems to work great (new user - so small sample size) for the things it does do, thanks!

FYI, I tried this old tool : https://aur.archlinux.org/packages/kazam/ which allows recording system and mic together.

What it seems to be doing is record both channel separately (In pulseaudio, it's showing kazam twice -- one is recording the system and the other mic) and then somehow mix them and quality is good.

Can a similar feature be implemented? Not asking for ETA but is it under consideration?
