nvjpeg2kDecode()

Decodes a single image, and writes it to the output device buffers. The function is synchronous with respect to the host. All GPU tasks will be submitted to the provided stream. Prior to calling this function user must parse the bitstream using nvjpeg2kStreamParse() such that the bitstream information is stored in jpeg2k_stream.

Signature:

nvjpeg2kStatus_t nvjpeg2kDecode(nvjpeg2kHandle_t handle,
        nvjpeg2kDecodeState_t decode_state,
        nvjpeg2kStream_t jpeg2k_stream,
        nvjpeg2kImage_t* decode_output,
        cudaStream_t stream);

Parameters:

Parameter	Input/Output	Memory	Description
nvjpeg2kHandle_t handle	Input	Host	library handle
nvjpeg2kDecodeState_t decode_state	Input	Host	decode state handle
nvjpeg2kStream_t jpeg2k_stream	Input	Host	nvjpeg2k bitstream handle
nvjpeg2kImage_t* decode_output	Input/Output	Host	pointer to an instance of component_info
cudaStream_t stream	Input	Host	Decode output struct. The struct should be on host memory. The image component pointers should point to device memory. See Image Data

Returns:

nvjpeg2kStatus_t - An error code as specified in API Return Status Codes
