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>
