I wonder if we should have a comment here about why other profiles are not
supported. Also, should they be NOTREACHED()?

[servolk, 2016/03/31 21:26:38]

Probably not worth adding the profiles 1-3 here explicitly, since we'll fall
into default case, which already has NOTREACHED anyway.
I'll add a comment though.

DCHECK(not the other three profiles)?

Similar below.

[servolk, 2016/03/31 21:26:38]

I've added some DCHECKs at the top of this method. There's no point in adding
DCHECKs here, since we'll reach NOTREACHED earlier when we call
GetVpxCodecParameters.
