Nope, just audio. None of my group have a camera in the first place (so we can't have video), but I wouldn't use it in any case since it takes up valuable screen real estate and doesn't offer much in return.*
We generally use chat for all in-character dialogue and limit voice discussion to rules questions and chit-chat anyway. We don't have plans to use video - the built-in audio is more than enough.
* It's actually one of my issues with Roll20 and some others - the map area has non-game... stuff ...covering parts of it. As a result, I keep it all minimized as much as possible. If I could have the toolbar, macro bar, and video doodads in an area separate from the map (like in a left column) I would find that much better for usability.
