Can I change v4l2 buffer timestamp from monotonic to real time?

Hi all,

When I check v4l2 buffer timestamp, it’s a monotonic timestamp.
Can I get this timestamp as real time?

Thanks in advance.

Sorry, not support. However you can reference to below topic to try to transfer it to real time.

Could you what topic can I reference? ( did you forget to link it? )

v4l2 timestamp issure

Hi, Team: In vi5_fops.c, I modifyed line 422 like this: /* Read SOF from capture descriptor */ ts = ns_to_timespec((s64)descr->status.sof_timestamp); get_monotonic_boottime(&tsa); printk("sec: %ld,nsec: %ld\n camerta sec: %ld,nsec: %ld\n", tsa.tv_sec, tsa.tv_nsec, ts.tv_sec, ts.tv_nsec); And then ts is 6 seconds longer than tsa. And i checked the cboot booting time in serial console just 6s， So how can we make the timestamp synchronization? Help.guys.it’s important for sensor fusion!
