You can use whichever you prefer (if you're using C, anyway).
The direct callbacks have less overhead of course.

How much less overhead?
I'm using the "signal" method as shown in the appsink-src.c example from the 10.28 Ubuntu source and everything works perfectly on a quad core, but can't quite keep up on a dual core. It falls behind slowly enough that our longest recording are still OK, but it messes up my attempt at putting a text overlay on each frame -- eventually the latter overlays appear on earlier frames.
I'd been going through the docs when I saw this, I'm having a bit of trouble setting up the GstAppSinkCallbacks structure. Do I put NULL for the callbacks I don't want? (which is all but "new-buffer")
