I would prefer this just taking in EglBase14.Context.

EglBase14 is not part of the api (it's a package-private class in the
src/java/... directory) and callers outside webrtc can't instantiate it.  I need
to take an argument that callers can actually create, or I can't reuse hardware
encoding in texture mode outside webrtc.
