We are doing the following to get timestamp information:
IArgusCaptureMetadata *iArgusCaptureMetadata = interface_cast<IArgusCaptureMetadata>(frame_buffer[i]);
if (!iArgusCaptureMetadata)
ORIGINATE_ERROR("Failed to get IArgusCaptureMetadata interface.");
CaptureMetadata *metadata = iArgusCaptureMetadata->getMetadata();
const Ext::ISensorTimestampTsc *sensorTSC = interface_cast<const Ext::ISensorTimestampTsc>(metadata);
On a Xavier NX running R32 (release), REVISION: 6.1, this works and we use sensorTSC->getSensorSofTimestampTsc() to get the timestamp. On an AGX Orin running R34 (release), REVISION: 1.1, we are running the same code, but sensorTSC is NULL.
We currently can only run Jetpack 5.0 on the Orin AGX, and not Xaviers, with the software given to us by the camera manufacturer. Our Xaviers are still running Jetpack 4.
