Subject: Remove unused functions
X-Git-Tag: 1.0_branch~511^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=47bc1c701346f032dd4e7586464f2185407f3378;p=profile%2Fivi%2Flibvpx.git

Remove unused functions

Remove estimate_min_frame_size() and calc_low_ss_err(), as they are
never referenced.
