Subject: vpxenc: fix time and fps calculation in 2-pass encoding
X-Git-Tag: 1.0_branch~92
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aabae97e57378356cdc8c94af5e369f8363b9831;p=profile%2Fivi%2Flibvpx.git

vpxenc: fix time and fps calculation in 2-pass encoding

When we do 2-pass encoding, elapsed time is accumulated through
whole 2-pass process, which gives incorrect time and fps results
for second pass. This change fixed that by resetting the time
accumulator for second pass.
