I am successfully extracting the frame number and timestamp in a GStreamer application using the GstBufferMetaData quark as described in another thread by @DaneLLL : Nvarguscamerasrc Buffer Metadata is missing - #29 by DaneLLL
What point in time does this timestamp represent? Is this stamped originally at the camera CMOS, on the way into the ISP, on the way out of the ISP, or somewhere else in the chain?
If important, I’m using JetPack 4.5.1 with nvarguscamerasrc.
