Don't have time for an answer today, maybe this will suffice for background audio..You can add after -i :0.0 this, `-f alsa -i pulse` plus also audio codec to be used, ex. `-c:a aac` or whatever. Then in at least Ubuntu a one time setup. Install `pavucontrol`, open it, click on the Recording tab. Start your ffmpeg command, you'll see `Alsa plugin [ffmpeg]` appear. Switch it to `Monitor of Built-in Audio ..` after this it'll always use the Monitor for the Alsa plugin. (Don't have a mic so never tried that audio input.. – doug Nov 29 '20 at 13:36

there is no Alsa plugin in `pavucontrol` after I start my [ffmpeg] cli – Slobodan Vidovic Nov 29 '20 at 14:54

Sorry, I glossed over your using a local server. What I described was how to input system audio into a ffmpeg recording/encoding. No clue what you'd do with ffserver now gone. – doug Nov 30 '20 at 16:34
