Or, you can use UScreenCapture. It's using the DShow API of DirectX, and available for both x86 and x64 architectures. After you installed it, you'll find a new input source "UScreenCapture", witch is your live desktop screen respectively.

If you're sending it to a Wowza server, here's the command what you need:

ffmpeg -f dshow -i video="UScreenCapture" -s **width** x **height** -r **framerate** -vcodec libx264 -pix_fmt yuv420p -b:v **bitrate** -an -vbsf h264_mp4toannexb -f mpegts udp://**your.destination.url:PORTNUMBER**?pkt_size=1316

Note that I explicitly changed the pixel format(pix_fmt), because ffmpeg used yuv444p instead of yuv420p. I had to do this to make it work.

It works pretty well for me.

  1. Download FFmpeg. Either 64-bit or 32-bit should work.

  2. Install Screen Capturer Recorder. The installer should automatically install Microsoft Visual C++ Redistributable as well, if needed.

  3. Use

    ffmpeg -f dshow -i video=screen-capture-recorder -r 24000/1001 -q 1 out.avi
    

FFmpeg screencast Windows

On Win systems the answer is unfortunately no. –  Gergely Lukacsy Jan 28 at 9:31
    
If you have Linux system (with running X server), you can use the built in x11grab device like this: ffmpeg -f x11grab -framerate 25 -video_size 1280x720 -i :0.0 [...] Check the official documentation [here].(ffmpeg.org/ffmpeg-devices.html#toc-x11grab) –  Gergely Lukacsy Jan 28 at 9:37
