<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> Hi all, I have a pipeline this: <pre style="background-color:#2b2b2b;color:#a9b7c6;font-family:'JetBrains Mono',monospace;font-size:9,8pt;">d3d11screencapturesrc monitor-handle={0} ! d3d11convert ! d3d11download</pre> using these caps: <pre style="background-color:#2b2b2b;color:#a9b7c6;font-family:'JetBrains Mono',monospace;font-size:9,8pt;">video/x-raw(memory:SystemMemory),width=3840,height=2160,sync=false</pre> This pipeline captures the screen using Windows DDUPL API thank to the gstreamer "d3d11screencapturesrc" and then return the captured frame with a callback to my program. If I capture in 4K at 60FPS it copies 60 frames per second into memory and this is quite heavy. Is there a way to optimize it? I only need to get the color information of some portion of that frames (top border, bottom border, right border, left border). Is there a way to optimize this pipeline? Thanks Davide </body> </html>
