Difference between StreamTime and HardwareReferenceTimeStamp

PostFri Aug 04, 2017 9:50 am

In the DeckLink SDK, when a video frame arrives, there are two functions that return a timestamp:

IDeckLinkVideoInputFrame::GetStreamTime - returns the time and duration of a captured video frame for
a given timescale.

IDeckLinkVideoInputFrame::GetHardwareReferenceTimestamp - returns frame time and frame duration for
a given timescale.

What is the difference between these two functions?

Thanks

Jules
