I'd like to know if
there are any additional parameters to record sound as well?

Code: Select all

ffmpeg -f x11grab -r 24 -s 1920x1080 -i :0.0 recorder.mp4

Hi
Here is a ffmpeg line I use in porteus 5.01

Code: Select all

ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 25 -s 1360x768 -i :0.0 -vcodec libx264 -preset ultrafast output.mkv
...be aware that porteus 5.1 switched to pipewire.

In the future, will I only change "pulse" to "pipewire"?

maybe, in some future yet to be realised timeline ;) ... i don't see any direct support for pipewire anywhere in ffmpeg at the moment.
but at this point (afaics and without testing), donald's ffmpeg command might work with pipewire as is, because it's supposed to have backward compatibility with pulse (through libpulse, which is present)

The truth is that any parameter for the audio reported an error to me.
