Hi guys,
For my usecase , I think I am no need to use gpu for speeding up my code .
But I want to use nvsample_cudaprocess source to handle my code . How Can I Use Multithread in the Given Source ?

Hi,

Could you share more detail about your use case and sample code?

Suppose that there is no much difference for multi-thread on Jetson.
You can design it with the general design guide for multi-thread on Linux.

Thanks.

Hi and good time
I wana use nvivafilter and nvsample for a processing application
In the sample you have wrote a funcation named
static void add_metadata(void ** usrptr)

And in the iva_metadata.h file is defined some metadata varible

typedef struct _location_t Location;

struct _location_t
{
int x1, y1;
int x2, y2;
};

typedef struct _bbox_t BBOX;

struct _bbox_t {
unsigned int framecnt;
unsigned int objectcnt;
Location location_list[NUM_LOCATIONS];
};

Right now,i wanna know how i can use the metadata in the gstreamer Main looper
For example ,how can i get the metadata in main gsteramer loop launcher??
May you help me??
Thank you for your time
Appreciate that
Best regards.
