The V4 API has:

    unsigned int frame_rate; /* in frames per 1000sec */

I would like to keep it the same way in both APIs. If you have strong
feelings about the enum, I'm going to change V4.

And BTW, if the frame rate changes, the size (and other fields
from the sequence header) are likely to change, too. You will
need two events then, but I guess that's the price you have
to pay for binary compatibility.

If you really need it in V3 (I know I'm way too slow with
my V4 work...), then go ahead and commit it.

Regards,
Johannes
