For Theora, you need to know when was the last keyframe, and the
number of keyframes total output so far. I think that should be enough.
That's a bit brittle to assume though.

Would adding another field to block_t be OK ? Would it break ABI, or
is it internal ? It wouldn't be so nice if it's just ogg specific, but still
better than reusing some other field.
