Considering that:
1) We have committed to an MTI video codec
2) All consensus calls on "VP8 only" and "H.264 only" have failed
3) This is the only proposal that gets support from both camps
I strongly support this MTI proposal.
Please, let's close this debate once and for all. This compromise is
by no means great, but it's much better than anything else we're going
to get otherwise (i.e. more wasted time and still no MTI).
