Use these values for x11grab. As for pulseaudio, it is probably easiest to: 1. Install pavucontrol 2. Start recording with ffmpeg 3. Start pavucontrol 4. Go to the Recording tab and you'll find "ffmpeg" or "Lavf*" (or similar) listed there 5. Change audio capture from "Internal Audio Analog Stereo" to "Monitor of Internal Audio Analog Stereo" The above list is adapted from: http://askubuntu.com/a/682793/59378 Now it should record "desktop" audio instead of the microphone. I don't use pulsaudio, so I don't know if you can change it to record only a particular application. So the inputs section of your command may look something like: ffmpeg -f x11grab -video_size <Width>x<Height> -i :0.0+<X>,<Y> -f pulse -i default ... _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
