I don't believe we have a quicktime project yet.

The whole gstreamer setup is based around elements: a plugin simply
provides some new elements for the gstreamer framework to use when dealing
with a file. What you would produce is a plugin (ie, dynamically loadable
library with appropriate interface), which provides an element or elements
to convert data in quicktime format into raw format, and back again.
It would be something which reads a stream of data from another element
processes it and passes it on to the next element. It shouldn't directly
read or write to disk or devices: we have other plugins to do that, so that
when a new file source comes along, only one new thing needs to be added.
This isn't clearly documented yet - I'm working on the Plugin Writers
Guide, but keep getting distracted by work, birthday parties, etc...
