VOXL camera server hires large & small frames in HAL3 PerCameraMgr
-
In the PerCameraMgr class, there is a function that process a single camera capture result (frame?) and prints the timestamp (meta.timestamp_ns).
We are attempting to compare the frame timestamp with the system time, which we have been able to do successfully, however it only looks like the camera frame is from hires small?
How can we distinguish between hires large and small in the hal3 camera manager code? We just need to compare timestamps but need to confirm if the metadata printed is from hires large or small, or both

All output pipes that begin with "hires" should have the same timestamp for each frame as they all come from the same image frame. the small and large pipes are simply different resolutions being encoded for different use cases from the same source camera frame
