hello wdouglass,
assume you’re working with l4t-r32.2,
there’s offset_ns device node, which is used to calculate the capture timestamp from system time.
it’s based-on below formula,
clock_gettime(MONOTONIC_RAW) = cycle_ns(TSC) - offset_ns
suggest you check Topic 1038131 for understanding timestamps.
please also check similar issues, such as Topic 1056202, and Topic 1046381 for reference.
BTW,
according to Camera Architecture Stack, there’re different software blocks to access camera sensors.
you may also refer to Topic 1057229 and apply the fix of missing VI buffer’s timestamp.
thanks
