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) |
| Encodes the specified frame with input Luma and Chroma quant tables and targetImageSize. More... | |
| NvMediaStatus | NvMediaIJPESetAttributes (const NvMediaIJPE *encoder, uint32_t attributeMask, const void *attributes) |
| Sets the JPEG encoder attributes. More... | |
| NvMediaStatus | NvMediaIJPEGetBits (const NvMediaIJPE *encoder, uint32_t *numBytes, void *buffer, uint32_t flags) |
| Returns a frame's worth of bitstream into the provided buffer. More... | |
| NvMediaStatus | NvMediaIJPEGetBitsEx (const NvMediaIJPE *encoder, uint32_t *numBytes, uint32_t numBitstreamBuffers, const NvMediaBitstreamBuffer *bitstreams, uint32_t flags) |
| Performs the same operation as NvMediaIJPEGetBits() except NvMediaIJPEGetBitsEx() consumes an array of buffers. More... | |
