I am trying to capture video and sound with the following command
ffmpeg -f dshow -r 15 -i video=screen-capture-recorder:audio="Desktop Microphone (2- HD-5000 - Microsoft LifeCam.)" -acodec mp3 -vcodec libx264 -y show.mp4
screen-capture-recorder is third-party dshow driver to capture screen and works ok.
"Desktop Microphone (2- HD-5000 - Microsoft LifeCam.)" is the name of my microphone, it is inside web camera of that name.
I found that recorder audio is periodically dying, i.e. becoming silent, fading out in vibrant noise.
The situation sounds like some level control works badly.
How to fix?
