We do have a directshow based solution in windows but are looking to migrate our development effort to Linux and would greatly appreciate any tips or pointers on how to achieve this. We are using Ubuntu 8.04.4 with Kernel 2.6.27.27. If someone is interested on helping us with this we will happy to compensate for your time and effort on a contract basis.

I recently completed some extension unit work, probably similar to what you're attempting. I could not find an official, authoritative source of documentation, but in the end the API is pretty straightforward.
