[gst-devel] v4l2src (harmless) warning, why?

I'm using Ubuntu 8.04 which appears to be gstreamer-0.10.18

Is there a reasonably easy way to build the current gstreamer without breaking the Ubuntu dependencies?

I'm thinking that using appsink might be better for my purposes that writing a filter element, although I've already succeded in writing a trivial plugin video filter (binary threshold an image).  Appsink doesn't seem to be part of my version of gstreamer.

At this point I'm exploring my options and trying to learn about alternatives before starting the version 2 redesign of my video image processing application that is currently done with a mix of v4l, v4l2,  Xlib code and a commercial UI library that doesn't appear to have much of a future.  Its on ubuntu 6.06 and has worked quite well so far, but code is very hard to follow using a lot of obsolete and arcane stuff basically lifted from XawTV and a few other things I'd found.  I suspect when I'm really ready to do it,  I'll be able to use Ubuntu 10.4.

What gst-plugins-good version are you using? I had a similar warning
but it has been fixed by
almost an year ago.
