<html><body><p><font size="4" face="Calibri">Performance of x.264 codec with FFmpeg on ppc64le is 30%-50% slower than on x86(Intel). This is in contrast to what is expected on Power8/LE. The x264 codec needs to be further optimized for Power8/LE as there is signification performance degradation on POWER. Attached are the test results for FFmpeg+x264 codec.</font><i>(See attached file: status_enabled_ppc.txt)</i><i>(See attached file: status_enabled_x86.txt)</i><br><br><font size="4" face="Calibri">FFmpeg was compiled as:</font><br><font size="4" face="Calibri">./configure --enable-gpl --enable-memory-poisoning --enable-avresample --enable-libx264 --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib</font><br><br><font size="4" face="Calibri">x264 codec is compiled as:</font><br><font size="4" face="Calibri">./configure --enable-shared --enable-static --enable-debug</font><br><br><font size="4" face="Calibri">Run time options used:</font><br><font size="4" face="Calibri">perf stat -o perf.log ffmpeg -i VanillaCakeRecipeDemonstration-Joyofbaking.com.mp4 -vcodec libx264 -acodec aac -strict experimental -threads 0 -level 31 -r 30000/1001 -b 1900k -pix_fmt yuv420p -tune ssim -profile high -vf setdar=16:9,setsar=1:1 -x264opts stats=x264_00_2pass.log:bframes=4:b-adapt=0:b-bias=20:b-pyramid=normal:ref=1:partitions=all:direct=auto:me=umh:merange=12:subme=9:trellis=0:no-fast-pskip=1:no-dct-decimate=1:fps=29.97 -f mp4 -y /dev/null</font><br><br><font size="4" face="Calibri">Machine Configuration : </font><i>(See attached file: Machine Configuration.txt)</i><br><br><font size="4" face="Calibri">Regards,</font><br><font size="4" face="Calibri">Duggirala Priya</font><font size="4" face="Calibri">.</font><BR>
