Functions
CUresult CUDAAPI	cuvidCreateDecoder (CUvideodecoder *phDecoder, CUVIDDECODECREATEINFO *pdci)
	In order to minimize decode latencies, there should be always at least 2 pictures in the decode queue at any time, in order to make sure that all decode engines are always busy. More...
CUresult CUDAAPI	cuvidDestroyDecoder (CUvideodecoder hDecoder)
	Destroy the decoder object. More...
CUresult CUDAAPI	cuvidDecodePicture (CUvideodecoder hDecoder, CUVIDPICPARAMS *pPicParams)
	Decode a single picture (field or frame) More...
CUresult CUDAAPI	cuvidMapVideoFrame (CUvideodecoder hDecoder, int nPicIdx, unsigned int *pDevPtr, unsigned int *pPitch, CUVIDPROCPARAMS *pVPP)
	Post-process and map a video frame for use in cuda. More...
CUresult CUDAAPI	cuvidUnmapVideoFrame (CUvideodecoder hDecoder, unsigned int DevPtr)
	Unmap a previously mapped video frame. More...
CUresult CUDAAPI	cuvidCtxLockCreate (CUvideoctxlock *pLock, CUcontext ctx)
	Context-locking: to facilitate multi-threaded implementations, the following 4 functions provide a simple mutex-style host synchronization. More...
CUresult CUDAAPI	cuvidCtxLockDestroy (CUvideoctxlock lck)
CUresult CUDAAPI	cuvidCtxLock (CUvideoctxlock lck, unsigned int reserved_flags)
CUresult CUDAAPI	cuvidCtxUnlock (CUvideoctxlock lck, unsigned int reserved_flags)
