Corentin Damman	1fb3e35708	cudamemorycopy: add D3D11 resource support ... Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1807>	2022-03-10 18:08:10 +00:00
Seungha Yang	e5132a8508	cudaupload,cudadownload: Add support for dGPU NVMM ... Implement NVMM <-> CUDA, GL, SYSTEM memory conversion. Jetson is not supported yet. Note that NVMM <-> GL interop on Jetson platform is supported by GstGL Some example pipelines are: - Convert NVMM to GstGL memory nvv4l2decoder ! "video/x-raw(memory:NVMM)" ! cudadownload ! "video/x-raw(memory:GLMemory)" ! glimagesink - Upload system memory to NVMM and encode video/x-raw,format=NV12 ! cudaupload ! "video/x-raw(memory:NVMM)" ! nvv4l2h264enc - Convert NVMM to GstCUDA memory and encode nvvideoconvert ! "video/x-raw(memory:NVMM)" ! cudaupload ! "video/x-raw(memory:CUDAMemory)" ! nvh264enc Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1865>	2022-03-07 19:05:29 +00:00
Seungha Yang	c31bf2db4d	nvcodec: Refactor cudaupload/download and add support for GL memory ... * Implement new baseclass GstCudaMemoryCopy to remove duplicated cudaupload/download code * Add support for CUDA <-> GL memory conversion via cudaupload/download Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1834>	2022-03-06 15:39:04 +00:00
Seungha Yang	ad0e7fca14	nvcodec: Refactor basetransform subclasses ... * cudaupload/download - Specify only formats actually we can deal with nvcodec elements, not all video formats - Supports CUDA output for download and input for upload in order to make passthrough possible, like other upload/download elements. * cudabasetransform - Reset conversion element if upstream CUDA memory holds different CUDA context and the element can accept it. This is the same behavior as corresponding d3d11 filter elements. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1834>	2022-03-06 15:39:04 +00:00
