Timecode from Ref Input?

PostMon Aug 02, 2021 12:39 pm

Hello, is it possible to get Timecode of incoming IDeckLinkVideoFrame frame in IDeckLinkVideoOutputCallback.ScheduledFrameCompleted callback, that works from Ref Input (synchro pulse)?
Or Timecode can only be obtained from incoming video from camera?

In case of working with Ref Input the timecode == null:
Code: Select all
void IDeckLinkVideoOutputCallback.ScheduledFrameCompleted(IDeckLinkVideoFrame completedFrame, _BMDOutputFrameCompletionResult result)
        {
            IDeckLinkTimecode timecode;
            completedFrame.GetTimecode(_BMDTimecodeFormat.bmdTimecodeLTC, out timecode);
            if (timecode != null)
...

Ref signal is Genlock / Blackburst and has NO time info in it at all. ;)
This signal is only used as a clock source to keep things happening at the same point in time.. But it's just a pulse.. ;)

Timecode can be derived from the SDI signal if a Timecode is present in the SDI signal from the source..
