Function Documentation

NvMediaStatus NvMedia2DGetVersion

(

NvMediaVersion *

version

)

Returns the version information for the NvMedia 2D library.

Parameters

[out]

version

A pointer to a NvMediaVersion structure filled by the 2D library.

Returns

NvMediaStatus, the completion status of the operation: NVMEDIA_STATUS_OK if successful, or NVMEDIA_STATUS_BAD_PARAMETER if the pointer is invalid.

NvMediaStatus NvMedia2DWeave	(	NvMediaDevice *	device,
		NvMediaImage *	imageOdd,
		NvMediaImage *	imageEven,
		NvMediaImage *	outImage
	)

Performs an NvMedia2D weave operation on NvMedia images.

2D weave interface takes frames containing odd and even lines as input. The destination frame is formed by interleaving odd and even lines.

The input frames must have the same format, which must be RAW8 or RGBA. The output frame format is always RGBA; the output frame has the same width as each input frame, and twice the height.

Parameters

[in]	device	NvMedia device handle.
[in]	imageOdd	A pointer to an NvMedia image representing odd lines.
[in]	imageEven	A pointer to an NvMedia image representing even lines.
[out]	outImage	A pointer to an NvMedia image containing weave output.

Returns

NvMediaStatus, the completion status of operation:

• NVMEDIA_STATUS_OK if successful.
• NVMEDIA_STATUS_BAD_PARAMETER if one or more parameter values are bad.
• NVMEDIA_STATUS_OUT_OF_MEMORY if the operation ran out of memory.
• NVMEDIA_STATUS_NOT_SUPPORTED if input surface types don't match.
• NVMEDIA_STATUS_BAD_PARAMETER if any mandatory pointer is invalid.
