DirectShow filter missing in FFMPEG

I am trying to stream system audio from Windows 10 via FFMPeg but my built-in audio output device (Realtek) does not show up when I run ffmpeg -list_devices true -f dshow -i dummy

ffmpeg direct show audio devices

But the realtek audio device works and it also shows up as registered in Graph Studio Next, a direct show device browser:

RealTek Audio DirectShow Filters

OS: Windows 10, 64 bit FFMPEG: 4.3.2 (latest)

Any ideas?

Solution

  • You need to enable the loopback device. It usually starts with 'Stereo Mix'.

    Go to Control Panel --> Sound --> Recording. Right-click and make sure all devices are shown. Enable the 'Stereo Mix'.
