Detailed Description

API-specific header for AV_HWDEVICE_TYPE_OPENCL.

Pools allocated internally are always dynamic, and are primarily intended to be used in OpenCL-only cases. If interoperation is required, it is typically required to allocate frames in the other API and then map the frames context to OpenCL with av_hwframe_ctx_create_derived().

Typedef Documentation

AVOpenCLDeviceContext

typedef struct AVOpenCLDeviceContext AVOpenCLDeviceContext

OpenCL device details.

Allocated as AVHWDeviceContext.hwctx

AVOpenCLFrameDescriptor

typedef struct AVOpenCLFrameDescriptor AVOpenCLFrameDescriptor

OpenCL frame descriptor for pool allocation.

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.

AVOpenCLFramesContext

typedef struct AVOpenCLFramesContext AVOpenCLFramesContext

OpenCL-specific data associated with a frame pool.

Allocated as AVHWFramesContext.hwctx.
