There's some nice documentation here: https://trac.ffmpeg.org/wiki/Capture/Desktop If ffmpeg is compiled with x11grab/xcbgrab, you can record a window by giving its position: https://www.ffmpeg.org/ffmpeg-devices.html#x11grab This doesn't accept window names or IDs though (unlike other tools might), and doesn't follow moving windows. As for pulseaudio, documentation seems to be sparse, but it should be possible to record from pulse. I believe I have done it. The wiki entry quoted above does have an "alsa with pulse" example. It also depends on whether you want to record a certain device (i.e. your microphone) or the audio *output*. For the latter, you may need to use the pulse tools to redirect that audio to a dedicated stream (or whatever it is called, I don't remember). Sorry, this is vague and probably insufficient info.
