## Constants

### GST_CAPS_FEATURE_MEMORY_CUDA_MEMORY

    #define GST_CAPS_FEATURE_MEMORY_CUDA_MEMORY "memory:CUDAMemory"

Name of the caps feature for indicating the use of GstCudaMemory

### GstCuda.CAPS_FEATURE_MEMORY_CUDA_MEMORY

Name of the caps feature for indicating the use of GstCuda.CudaMemory

### GstCuda.CAPS_FEATURE_MEMORY_CUDA_MEMORY

Name of the caps feature for indicating the use of GstCuda.CudaMemory

### GST_CUDA_MEMORY_TYPE_NAME

    #define GST_CUDA_MEMORY_TYPE_NAME "gst.cuda.memory"

Name of cuda memory type

### GstCuda.CUDA_MEMORY_TYPE_NAME

Name of cuda memory type

### GstCuda.CUDA_MEMORY_TYPE_NAME

Name of cuda memory type

### GST_MAP_CUDA

    #define GST_MAP_CUDA (GST_MAP_FLAG_LAST << 1)

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

### GstCuda.MAP_CUDA

Flag indicating that we should map the CUDA device memory instead of to system memory.

Combining GstCuda.MAP_CUDA with Gst.MapFlags.WRITE has the same semantics as though you are writing to CUDA device/host memory. Conversely, combining GstCuda.MAP_CUDA with Gst.MapFlags.READ has the same semantics as though you are reading from CUDA device/host memory

### GstCuda.MAP_CUDA

Flag indicating that we should map the CUDA device memory instead of to system memory.

Combining GstCuda.MAP_CUDA with Gst.MapFlags.WRITE has the same semantics as though you are writing to CUDA device/host memory. Conversely, combining GstCuda.MAP_CUDA with Gst.MapFlags.READ has the same semantics as though you are reading from CUDA device/host memory
