We will have to do some work on the internal properties APIs in GStreamer to
allow a property's default value to be 'not set' so that the default value can
be punted to libx264. I think this will be the most desirable solution for both
parties and the best compromise.

If we do this, in the next release notes for -ugly, we must make note of
changes that affect compatibility. For example, currently the element outputs
Main Profile (baseline + cabac) I think whereas libx264 will default to High
Profile. As such, we should make sure to detail how to preserve previous levels
of compatibility through specifying which property to set to which value to
preserve the 'status quo' w.r.t. H.264 profile.

Jason: If you can slap together a patch of what needs changing/updating with
x264enc, it would be a useful starting point for getting it merged into
GStreamer once someone has looked into the GStreamer properties issue that will
enable the changes.
