[FFmpeg-user] Injecting clock based TC at first frame captured

[Steinar Apalnes]

Hi,

I'm doing a lot of capturing through decklink video devices and I was
wondering if it was, or would be possible to make ffmpeg set a frame
accurate start TC based on wall clock when the first frame was captured?
An option like this maybe:

-tc_inject 1

Where 1 could be the first frame.

or

-tc_inject now
-timecode now

Maybe this kind of option exist or maybe there are other good ways of
solving the "problem" but I have yet to find a solution.

Thanks!
