AERegion property on nvarguscamerasrc

Hi all,

One of our customers have been using the aeregion property on nvcamerasrc, now they ported the system to Jetpack 4.2.2, and started using nvarguscamerasrc instead. However, nvarguscamerasrc doesn’t have the aeregion property to control the ROI of the autoexposure feature in LibArgus.

Are you planning to add this feature in a short term? If not, what is your recommendation for us?

hello CarlosR92,

there’s setAeRegion API to specify the AE region of interest (ROI).
the exposure algorithm currently does not ignore the area outside the ROI completely. it gives more weights to the region selected instead.

please also refer to similar discussion thread, Topic 1064309.
FYI, we don’t have plan to update the AE algorithms to modify AE region behaviors so far,
thanks

Hi @JerryChang,

Yes, We have seen there is an API for AE ROI feature on LibArgus, but the problem is that it is not exposed in nvarguscamerasrc GStreamer elements as it was on nvcamerasrc.

Are you planning to add a property to nvarguscamerasrc element to control the AE ROI?

hello CarlosR92,

currently, you’ll need to control AE region of interest through MMAPIs.
thanks

Could NVIDIA please just release the nvarguscamerasrc source code? This way the community could fix its numerous issues…
