I'll start by looking if I'm using D3D11 aware elements/components. Anyway thanks for all the hints.

What's the consumer of "new pipeline" (how did you read the output buffer)? If it's not a D3D11-aware element/component, the "new pipeline" would not boost any performance. Note that CPU read/writable memory layout of Direct3D11 memory might be different from that of normal CPU memory. To read video memory, don't assume that stride/pitch is equal to width but you should use gst_video_frame_map() or so.

Hi all, I'm screen capturing using GStreamer bindings for Java without problems since a lot of time, it works super awesome at all screen resolutions. Love GStreamer and the Java Bindings for GStreamer. :) Thank you all for this awesome things. I'm using a pipeline like this: d3d11screencapturesrc monitor-handle={0} ! d3d11convert ! d3d11download ! video/x-raw(memory:SystemMemory),width=3440,height=1440 this pipeline works as expected. I recently switched to this "new pipeline" that should be more optimized for the purpose: d3d11screencapturesrc monitor-handle={0} ! d3d11convert ! video/x-raw(memory:D3D11Memory),width=3440,height=1440 this "new pipeline" works well at every screen resolutions except 3440x1440, I even tried another 21:9 resolution like 3840x1080 and it works well but not on 3440x1440. All other screen resolutions works well. This is so weird. My code should be ok since if I switch to the "older pipeline" all works well. I took a screenshot at 3440x1440 when capturing the screen and the image is completely scrambled, I attach it. I don't know how where to start finding for a solution. Is this a problem related to the bindings? Is there some errors in my pipeline? How can a pipeline works well at every screen resolutions and not at 3440x1440? Thank you Davide</div> </blockquote> </body></html>
