does it make sense to have two flags?

[fgalligan1, 2012/12/13 22:30:14]

I wasn't sure about that. But I didn't want to add more flags than needed. I
think most clients will add support for both around the same time.

[Tom Finegan, 2012/12/13 23:20:00]

I don't think so-- I don't think there's any benefit to enabling the new WebM
codecs individually. We can always use audio or video only files if one the
wrappers need to be isolated for testing.
