Is this a regression from 2.0?

No need to modify anything, there's an option in advanced settings on
the connect dialog page.

It shows "auto" because that's the best encoding selection policy
available, it may use any of the encodings available, including "h264".

It probably is used, but it is hidden in the advanced options because it
doesn't work reliably. I don't recommend it.

Please file a ticket with enough details.
