Get frame timer when capturing camera fram

[Cyrille de Brebisson]

Good morning,

Apparently, cameras send a high precision time stamp with every frame sent to the computer (as defined in the UVC standard).

Is there a way, using QCamera and QVideoSink to access this time stamp? My application need accurate timing of frames and "just get the time when you get the frame" is not good enough in our case.

Thanks,
Cyrille

Hi,

I don't currently know but maybe the QVideoFrame::startTime method might be of help.
