[FFmpeg-user] Screen Capture - Windows 10

[Ron Barnes]

I was able to install the screen capture recorder and still no joy.  How do the commercial vendors do it?
☹

As already mentioned, the hardware acceleration of your browser can apparently not be captured.

You're using gdigrab for video. Have you tried adding the dshow capture device?
https://github.com/rdp/screen-capture-recorder-to-video-windows-free

If you install it, your "ffmpeg -list_devices true -f dshow -i dummy"
should show a new video device "screen-capture-recorder". Perhaps that works for you. (I have no experience with it - it may suffer the same limitation. Please do report.)

Cheers,
Moritz
