I am trying to compile ffmpeg on Xeon Phi processor. Are there any specific compiler optimization flags specific for Xeon Phi that I can enable while configuring ffmpeg so that I can achieve better performance in terms of encoder frames per second?
Encoder used: x264 Operating System: CentOS 7.2 Compiler: GCC 4.8.5
Currently, I am configuring ffmpeg with the below command line:
./configure --prefix="$HOME/ffmpeg_build"
--extra-cflags="-I$HOME/ffmpeg_build/include"
--extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin"
--pkg-config-flags="--static" --enable-gpl --enable-nonfree
--enable-libx264
