Functions
NvMediaStatus	NvMediaIJPEGetVersion (NvMediaVersion *version)
	Gets the version compatibility for the NvMedia IJPE library. More...
NvMediaIJPE *	NvMediaIJPECreate (const NvMediaDevice *device, NvMediaSurfaceType inputFormat, uint8_t maxOutputBuffering, uint32_t maxBitstreamBytes)
	Creates a JPEG encoder object capable of turning a stream of surfaces of the inputFormat into a JPEG stream. More...
void	NvMediaIJPEDestroy (NvMediaIJPE *encoder)
	Destroys an NvMedia image JPEG encoder. More...
NvMediaStatus	NvMediaIJPEFeedFrame (const NvMediaIJPE *encoder, NvMediaImage *frame, uint8_t quality)
	Encodes the specified frame with input quality. More...
NvMediaStatus	NvMediaIJPEFeedFrameQuant (const NvMediaIJPE *encoder, NvMediaImage *frame, uint8_t *lumaQuant, uint8_t *chromaQuant)
	Encodes the specified frame with input Luma and Chroma quant tables. More...
NvMediaStatus	NvMediaIJPEFeedFrameRateControl (const NvMediaIJPE *encoder, NvMediaImage *frame, uint8_t *lumaQuant, uint8_t *chromaQuant, uint32_t targetImageSize)
