Detailed Description

CUDA frame descriptor for pool allocation of AV_PIX_FMT_CUARRAY frames.

In user-allocated pools, AVHWFramesContext.pool must return AVBufferRefs with the data pointer pointing at an object of this type describing the planes of the frame.

This has no use outside of custom allocation, and AVFrame AVBufferRef do not necessarily point to an instance of this struct.

Field Documentation

array

CUarray AVCUDAArrayFrameDescriptor::array

The CUarray containing the frame data.

Normally stored in AVFrame.data[0].

Definition at line 66 of file hwcontext_cuda.h.

index

intptr_t AVCUDAArrayFrameDescriptor::index

The index into AVCUDAFramesContext.cuarray_surfaces, or 0 if not applicable.

Normally stored in AVFrame.data[1] (cast from intptr_t).
