Subject: Allow disable of refresh golden for more than 1 layer encoding.
X-Git-Tag: v1.4.0~542^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d6b688375fe10d8fa1b0f6d565013e78f223aad8;p=platform%2Fupstream%2Flibvpx.git

Allow disable of refresh golden for more than 1 layer encoding.

The current logic was allowing for disabling golden refresh only
for two pass svc encoding. This change disables it as long as
more than 1 layer encoding is used (for example temporal layers under 1pass CBR).
