What you are after is a video delayline.. These are, err... were common on Time Base Correctors (TBC)'s in the analog days of video.

At what resolution??? 720p? 1080p?

The audio sync is not important? or you want to delay it as well?

I am just guessing, but even with a Pi3 maxed out on CPU Freq. might not be up to the task, espeically at 1080p. And 720p might be pushing it..

Maybe do the delay OUTSIDE the Pi... with some of these:

Then recombine all the stuff to your desired format for "broadcast/delivery."

SOme FYI....

This probably does what you want on a software side, but unfortunately uses an overpriced crapple... but you might review the source and see if you can rework it to ARMHF and the Pi's

Hardware support for the video digitizer etc., and possibly memory could all be issues for this....

Can you leave politics out of this group, please? Or at least use a standard sig separator dash-dash-space-newline so people may opt out by using the appropriate filter/setting in their usenet readers.

Like so. Note the space after the two dashes.

A. Dumas (how unusually self aware) - as well as political fanaticism, how about also dealing with people making different computing choices, and realise that one person's different choices don't magically invalidate your own choice. Bonus points if you can apply that principle to your interactions with the wider world.

Seriously - I'm sick to death of desperately insecure zealots. They're just banal and worthless, after my 20 years in Usenet.
