//! 1. Application fills IN parameters CodecType, ChromaFormat and BitDepthMinus8 of CUVIDDECODECAPS structure
//! 2. On calling cuvidGetDecoderCaps, driver fills OUT parameters if the IN parameters are supported
//! If IN parameters passed to the driver are not supported by NVDEC-HW, then all OUT params are set to 0.

//! App fills - eCodecType = cudaVideoCodec_H264; eChromaFormat = cudaVideoChromaFormat_420; nBitDepthMinus8 = 0;
//! Given IN parameters are supported, hence driver fills: bIsSupported = 1; nMinWidth = 48; nMinHeight = 16;
