PS:<br>
I noticed that this happen when using dxgiscreencapsrc but not when
using dx9screencapsrc.<br>
This is really bad since dxgiscreencapsrc is so better.<br>
<br>
Thanks<br>

Hi guys, <br>
I have noticed a very strange behaviour when screen capturing
using gstreamer.<br>
<br>
I am using this command line for my try in Windows 10.<br>
<br>
./gst-launch-1.0 dxgiscreencapsrc ! videoscale method=0 !
videoconvert ! autovideosink sync=false<br>
<br>
This command launch a gstreamer window where I can see my screen
beeing captured. <br>
The command capture at a locked 30 FPS no matter what other
software or windows I open.<br>
<br>
If I open an OpenGL/Vulkan or DX11/DX12 window, screen capture
remains at a locked 30FPS <br>
but as soon as I click on the 3D window the screen capture
framerate drops significantly to 10FPS or even worse.<br>
<br>
It's strange because if I change the focus on a non 3D window,
without closing the 3D window,<br>
the framerate returns to 30FPS.<br>
Note that framerate drops occurs in the screen capture window, not
in the 3D window.<br>
<br>
How this is possible?<br>
Is there a way to fix this problem?<br>
<br>
Thank you all guys, I really appreciate your work here and the
help you give people on this community :)<br>
<br>
Bye<br>
Davide<br>
