From: Cheng Chen Date: Thu, 15 Apr 2021 05:15:54 +0000 (-0700) Subject: Pass vizier rd parameter values X-Git-Tag: v1.11.0-rc1~58 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=665cccfd6ccbc1be2db7d550b68388679b573410;p=platform%2Fupstream%2Flibvpx.git Pass vizier rd parameter values Add command line options for three rd parameters. They are controlled by --use_vizier_rc_params, together with other rc parameters. If not set from command line, current default values will be used.
