msys2 complete x264 development

Like previous post, this post will guide you to make your own x264 build under Windows by using msys2

Update msys2

Skip this if you already done, just in case msys2 have new package, open msys2 64-bit

pacman -Syu

Press Y and wait until you see this screen, simply exit terminal without CTRL+C

Install required package

x264 require some other tool to work, for example, output to mp4 require GPAC MP4Box or L-SMAH, to read any file without pipe, require libav or ffms2.

Download compiler tools

pacman -S --needed base-devel git subversion mercurial nasm yasm mingw-w64-x86_64-toolchain

Download x264 required source

pacman -S --needed mingw-w64-x86_64-ffms2 mingw-w64-x86_64-gst-libav mingw-w64-x86_64-l-smash

Compile x264

Now, we can compile, first, we need clone x264 project

If you using AMD Ryzen/Threadripper/Epyc (Zen 2), it’s good time to run compiler optimization:

Then, you can start compile as usual

git clone
cd ~/x264
./configure --extra-cflags="-march=znver2" --enable-static --bit-depth=8


./configure --extra-cflags="-march=znver2" --enable-static --bit-depth=10

Make sure the configure is configured like this:

shared:        no
static:        yes
asm:           yes
interlaced:    yes
avs:           avisynth
lavf:          yes
ffms:          yes
mp4:           lsmash
opencl:        yes

Then start make

Copy dependency

If your compiled binary not working, it’s time to make a jail version of x264 by copying all required file to a folder you like.

mkdir ~/jail
cp x264 ~/jail
ldd x264 | grep "=> /" | awk '{print $3}' | grep "/ming" | xargs -I '{}' cp -v '{}' ~/jail

Command grep "/ming" is skipping Windows DLL file, copy only mingw DLL
