Field Documentation

cuarray_desc

CUDA_ARRAY3D_DESCRIPTOR AVCUDAFramesContext::cuarray_desc

CUDA_ARRAY3D_DESCRIPTOR CUarrays will be initialized with.

Mostly used to provide external Flags.

Width, Height and Format only honored if != 0. Filled with default parameters from the FramesContext otherwise.

Only applicable for AV_PIX_FMT_CUARRAY.

Definition at line 89 of file hwcontext_cuda.h.

Referenced by cuda_frames_init(), cuda_pool_alloc(), cuvid_handle_video_sequence(), and ff_nvdec_decode_init().

cuarray_num_surfaces

int AVCUDAFramesContext::cuarray_num_surfaces

If >0, pre-allocate a fixed pool of surfaces.

The surfaces will be available via cuarray_surfaces after init. Size of the pool cannot be changed afterwards.

Only applicable for AV_PIX_FMT_CUARRAY.

cuarray_surfaces

CUarray* AVCUDAFramesContext::cuarray_surfaces

If cuarray_num_surfaces is >0, this contains the array of pre-allocated surfaces.

Only applicable for AV_PIX_FMT_CUARRAY.

Definition at line 105 of file hwcontext_cuda.h.
