Hi team i am trying to set the roi region for my imx415 camera in jetpack 5.1.2 in nvidia xavier nx (developer kit )
i wan able to see the roi in nvidia argus multimedia application by add the below code /Set ROI Exposure/
std::vectorArgus::AcRegion regions;
weight = (float)Weight;
weight/=100;
if(ROI_X1 != 0 || ROI_Y1 != 0 || ROI_X2 != 0 || ROI_Y2 != 0 || weight !=0)
{
Argus::AcRegion roi(ROI_X1,ROI_Y1,ROI_X2,ROI_Y2,weight);
printf(“Setting ROI Coordinates: x0= %d\ty0 = %d\tx1 = %d\ty1 = %d\t weight_percent = %d%%\n”,ROI_X1,ROI_Y1,ROI_X2,ROI_Y2,Weight);
regions.push_back(roi);
iAutoControlSettings->setAeRegions(regions);
iAutoControlSettings->setAfRegions(regions);
iAutoControlSettings->setAwbRegions(regions);
} but i want to add the roi control in my nvid aargus camera application to set the roi co ordinates dynamically so that i can change the ae roi region from the argus application
need support on this .

hello herethehacker97,

may I know what’s the actual use-case for setting AeRegion dynamically?
there’re some limitations of AeRegion, please see-also Topic 308574 for more details.

Thanks for your reply, i was trying to set the roi values dynamically .to specify the region i want to see how it works .

Does it have any impact if i tried to set roi values continuously.
I am getting the camera stream to stoped if i tried to set the ae roi region two to three times again i need to restart my apllication. below is the reference imaage i added the roi in ui in argus application.

my question are

  1. can i set my ae roi dynamically?
  2. does it will crash or stop the camera if i constantly changing my ae roi region ?
  3. or do we have any other option to set the ae roi dynamically while my camera is streaming?

hello herethehacker97,

I’m checking this internally.
please restart capture pipeline for setting different AeRegion at the moment.

Hi @JerryChang did you got any possibilities for the above query?

hello herethehacker97,

please restart capture pipeline for setting different AeRegion.
Argus cannot support setting different AeRegion on the fly, it’s a feature request to change AeRegion dynamically.
