Define Documentation

#define GET_NVAPI_SIZE ( ver   )     (NvU32)((ver) & 0xffff)

#define GET_NVAPI_VERSION ( ver   )     (NvU32)((ver)>>16)

#define MAKE_NVAPI_VERSION ( typeName,
ver   )     (NvU32)(sizeof(typeName) | ((ver)<<16))

NvAPI Version Definition Maintain per structure specific version define using the MAKE_NVAPI_VERSION macro. Usage: define NV_GENLOCK_STATUS_VER MAKE_NVAPI_VERSION(NV_GENLOCK_STATUS, 1)

#define NV_MAX_HEADS   4

#define NV_MAX_VID_PROFILES   4

Maximum number of output video profiles supported.

#define NV_MAX_VID_STREAMS   4

Maximum number of input video streams, each with a NVAPI_VIDEO_SRC_INFO.
