I wrote a script to record my computer screen, my computer audio (The audio coming out of my speakers), and my microphone using ffmpeg:
ffmpeg -video_size 1920x1080 -framerate 60
-f x11grab -i :0.0
-f pulse -i default
-f openal -i "Monitor of Headset H390 Analog Stereo" \
-c:v libx264rgb -crf 0 -preset ultrafast video.mkv
It records the video correctly, but not the audio. Only the first audio source (my microphone) is recorded. If I swap the order of -f pulse -i default and -f openal -i "Monitor of Headset H390 Analog Stereo", only my computer audio is recorded. How can I record my computer audio and my microphone at the same time? (Preferrably to different tracks so I can change the volume individually while editing.)
My operating system is Linux Mint 5.3.0-51.
