Implement precision time sync by reading PTS/USB frame correlation from firmware

Open wes-b opened this issue 5 years ago • 2 comments

This is for scenarios when a solution needs high precision timestamps that allow the user to know exactly when an image was captured as referenced to the system time, rather than the device time.

Is your feature request related to a problem? Please describe. For late stage rendering, precision between the system time and the device time is needed. This is needed so that system time can measure overall system performance and latency.

#198 captures the first part of addressing this, while this issue specifically address fixing the precision part of the issue.

Maybe worth looking into this: WinUsb_StartTrackingForTimeSync

Yes, this is great for windows, support on Linux is the question. I think we will need USB driver enhancements on Linux to do this there.
