Name of the caps feature for indicating the use of #GstCudaMemory Name of cuda memory type A #GstAllocator subclass for cuda memory A newly created #GstCudaBufferPool The #GstCudaContext to use for the new buffer pool Create #GstCudaContext with given device_id a new #GstCudaContext or %NULL on failure device-id for creating #GstCudaContext Note: The caller is responsible for ensuring that the CUcontext and CUdevice represented by @handle and @device stay alive while the returned #GstCudaContext is active. A newly created #GstCudaContext A [CUcontext](https://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__TYPES.html#group__CUDA__TYPES_1gf9f5bd81658f866613785b3a0bb7d7d9) to wrap A [CUDevice](https://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__TYPES.html#group__CUDA__TYPES_1gf9f5bd81658f866613785b3a0bb7d7d9) to wrap Pops the current CUDA context from CPU thread %TRUE if @ctx was pushed without error. Query whether @ctx can access any memory which belongs to @peer directly. %TRUE if @ctx can access @peer directly a #GstCudaContext a #GstCudaContext Get CUDA device context. Caller must not modify and/or destroy returned device context. the `CUcontext` of @ctx a #GstCudaContext Get required texture alignment by device the `CUcontext` of @ctx a #GstCudaContext Pushes the given @ctx onto the CPU thread's stack of current contexts. The specified context becomes the CPU thread's current context, so all CUDA functions that operate on the current context are affected. %TRUE if @ctx was pushed without error. a #GstCudaContext to push current thread Free @resource a #GstCudaGraphicsResource Map previously registered resource with map flags the `CUgraphicsResource` if successful or %NULL when failed a #GstCudaGraphicsResource a CUstream a CUgraphicsMapResourceFlags @resource a #GstCudaGraphicsResource Register the @buffer for access by CUDA. Must be called from the gl context thread with current cuda context was pushed on the current thread whether @buffer was registered or not a GL buffer object a `CUgraphicsRegisterFlags` Unmap previously mapped resource a #GstCudaGraphicsResource a `CUstream` Unregister previously registered resource. For GL resource, this method must be called from gl context thread. Also, current cuda context should be pushed on the current thread before calling this method. a #GstCudaGraphicsResource Create new #GstCudaGraphicsResource with given @context and @type a new #GstCudaGraphicsResource. Free with gst_cuda_graphics_resource_free a #GstCudaContext a graphics API specific context object a #GstCudaGraphicsResourceType of resource registration Ensures that the #GstCudaAllocator is initialized and ready to be used. the device memory needs downloading to the staging memory the staging memory needs uploading to the device memory Flag indicating that we should map the CUDA device memory instead of to system memory. Combining #GST_MAP_CUDA with #GST_MAP_WRITE has the same semantics as though you are writing to CUDA device/host memory. Conversely, combining #GST_MAP_CUDA with #GST_MAP_READ has the same semantics as though you are reading from CUDA device/host memory a new #GstContext embedding the @cuda_ctx a #GstCudaContext Perform the steps necessary for retrieving a #GstCudaContext from the surrounding elements or from the application using the #GstContext mechanism. If the content of @cuda_ctx is not %NULL, then no #GstContext query is necessary for #GstCudaContext. whether a #GstCudaContext exists in @cuda_ctx the #GstElement running the query preferred device-id, pass device_id >=0 when the device_id explicitly required. Otherwise, set -1. the resulting #GstCudaContext Create new #GstCudaGraphicsResource with given @context and @type a new #GstCudaGraphicsResource. Free with gst_cuda_graphics_resource_free a #GstCudaContext a graphics API specific context object a #GstCudaGraphicsResourceType of resource registration Whether the @query was successfully responded to from the passed @context. a #GstElement a #GstQuery of type %GST_QUERY_CONTEXT a #GstCudaContext Helper function for implementing #GstElementClass.set_context() in CUDA capable elements. Retrieves the #GstCudaContext in @context and places the result in @cuda_ctx. whether the @cuda_ctx could be set successfully a #GstElement a #GstContext preferred device-id, pass device_id >=0 when the device_id explicitly required. Otherwise, set -1. location of a #GstCudaContext Loads the cuda library %TRUE if the libcuda could be loaded %FALSE otherwise Ensures that the #GstCudaAllocator is initialized and ready to be used. Source code to compile Loads the nvrtc library. %TRUE if the library could be loaded, %FALSE otherwise the GQuark for given @id or 0 if @id is unknown value a #GstCudaQuarkId CUDA device API return code `CUresult` Check if @mem is a cuda memory A #GstMemory
