Subject: Align the quantizers for inter/inter modes in the first pass coding
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2ad40b89b337060da90c836c6a1a2af7f6f1b6a3;p=libvpx

Align the quantizers for inter/inter modes in the first pass coding

Use regular extended zero bin quantizer for both inter and intra
modes in the first pass. This doesn't affect lowres and midres
significantly, but would bring back 0.9% coding gains for hdres.
