Comment (by MB SOFT):

 Replying to [comment:11 malaawar]:
 > Interesting, but it is able to capture the application's screen from
 some other laptops i tested on. Do you by any chance know of other good
 open source alternatives?

 yes you can do it with gstreamer

 https://gstreamer.freedesktop.org/documentation/d3d11/d3d11screencapturesrc.html
 ?gi-language=c#d3d11screencapturesrc

 this is a pipeline that i use everyday to capture a window and encode it
 in an h265 mkv file:

 {{{
 gst-launch-1.0.exe -e --gst-debug=3 d3d11screencapturesrc capture-api=1
 window-handle=1117566 window-capture-mode=1 !
 video/x-raw(memory:D3D11Memory),framerate=30/1 ! d3d11convert ! queue !
 mfh265enc bitrate=416 quality-vs-speed=100 low-latency=true ! h265parse !
 queue ! matroskamux name=mux streamable=true offset-to-zero=true ! queue !
 filesink location="D:\\90Giorni\\2025-04-12_0000.mkv"
 }}}

 hope to see windows graphics capture api implemented also in ffmpeg one
 day
