Re-negotiates with updated size on desktop size (i.e., resolution, scaling factor), and rotation mode change Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2268>	2021-05-20 17:05:24 +00:00
Seungha Yang	0f7af4b143	d3d11: Move core methods to gst-libs ... Move d3d11 device, memory, buffer pool and minimal method to gst-libs so that other plugins can access d3d11 resource. Since Direct3D is primary graphics API on Windows, we need this infrastructure for various plugins can share GPU resource without downloading GPU memory. Note that this implementation is public only for -bad scope for now. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/464>	2021-01-13 15:01:20 +00:00
Seungha Yang	2ca298d459	d3d11: Re-implement Desktop Duplication source ... Add a new video source element "d3d11desktopdupsrc" for capturing desktop image via Desktop Duplication based on Microsoft's Desktop Duplication sample available at https://github.com/microsoft/Windows-classic-samples/tree/master/Samples/DXGIDesktopDuplication This element is expected to be a replacement of existing dxgiscreencapsrc element in winscreencap plugin. Currently this element can support (but dxgiscreencapsrc cannot) - Copying captured D3D11 texture to output buffer without download - Support desktop session transition e.g., can capture desktop without error even in case that "Lock desktop" and "Permission dialog" - Multiple d3d11desktopdupsrc elements can capture the same monitor Not yet implemented features - Cropping rect is not implemented, but that can be handled by downstream - Mult-monitor is not supported. But that is also can be implemented by downstream element for example via multiple d3d11desktopdup elements with d3d11compositor Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1855>	2020-12-22 19:23:25 +00:00
