Hi,
How can I change csi camera (nvarguscamerasrc) properties like aelock, exposure while running deepstream pipline on the XavierNX.
Thanks

hello yaniv.nahum,

you cannot configure exposure values while AE lock enabled; could you please share the actual use-case for reference,
there’s Argus sample code you may check for your implementation.
for example,
/usr/src/jetson_multimedia_api/argus/samples/userAutoExposure/
there’s API to configure exposure values, iSourceSettings->setExposureTimeRange()

you may also check Jetson Linux API Reference for the documentation,
thanks

Hi Jerry,
I’m aware I can’t change exposure while aelocked.
I changed the camera source bin to disable the aelock:
g_object_set (G_OBJECT (bin->src_elem), “aelock”, FALSE, NULL);

I’ll check the jetson_multimedia_api now.
will it work while the deepstream pipeline is running?
Is there an option to set ROI rect for auto exposure?
Thanks
