Macros

#define NV_TAGCAT_APP   0x4000
 
#define NV_TAG_APP(idx)   (NV_TAGCAT_APP | ((idx) & 0x3FFF))
 Get NVDS tag for user application. The values of Tag 0x0000 and 0xFFFF are invalid. idx should not be used as the parameter of NVDS APIs directly. The range of idx is 0x0001~0x3FFF. More...
 

Typedefs

typedef uint16_t NvdsTag_t
 NVDS Item tag. More...
