Zeranoe-Replicating FFMpeg Build

This is a modified version of DeadSix27's Python Cross Compile Script to replicate the Zeranoe ffmpeg builds.

Run the following commands to get the script's dependencies.

It's possible that some of these dependencies are not necessary, but this is what was installed on a fresh Ubuntu VM when I ran this script successfully.

sudo apt-get install ragel curl libtool autoconf pkg-config zlib1g-dev mercurial unzip autogen bzip2 autoconf-archive p7zip-full python3-distutils -y

sudo apt-get install python3 python3-pip

sudo apt-get install subversion texinfo yasm git make automake gcc g++ pax cvs flex bison patch nasm cmake rake gperf gyp p7zip docbook2x nasm

sudo apt-get install autopoint

pip3 install requests progressbar2

pip3 install meson

Before running the script,

• Make sure the git repo url and branch look correct in packages/products/ffmpeg_static.py
• Make sure the dependencies look correct in packages/dependencies/ffmpeg_depends.py
• Make sure that the build flags look correct in packages/variables.py.

Run the script with

./cross_compiler.py -p ffmpeg_static

---

Details

The script is going to first build MinGW-w64.

• Will take awhile, but once it's built, it won't need to build again as long as it stays in workdir/toolchain.
• This is what will be used to cross-compile everything to Windows

The script will then use the compiled toolchain to build all of the ffmpeg dependencies listed in packages/dependencies/ffmpeg_depends.py and the sub-dependencies of those dependencies.

• Like the toolchain, once these dependencies are built, they will stick around and the script won't try to rebuild them unless the source repository changes for any of the dependencies.
• Many of these dependencies are patched by the script before building. The patches are located in the patches directory
• It isn't known what all of the patches are that Zeranoe has done, but after an investigation with Wireshark, the Zeranoe builds seem to have disabled TLS 1.3 in the GnuTLS package. (An important patch to get Facebook rtmps livestreaming to work)
• More can be read about this in a discussion I had on the Zeranoe forum

Finally, the script will begin to configure and build ffmpeg with all of the build flags defined in packages/variables.py and some extras like --libbluray in packages/products/ffmpeg_static.py

Once everything has been built for the first time, if you need to make changes to the ffmpeg code, you can run make manually inside workdir/x86_64_products/ffmpeg_static_git.

• This will allow make to build only the files that you have changed rather than the entire ffmpeg project
• If you re-run the script instead, the dependencies won't be rebuilt, but the entire ffmpeg project will be rebuilt (Which can take about an hour)
• To get this to work, you have to add this to your PATH environment variable /home/username/python_cross_compile_script/workdir/toolchain/x86_64-w64-mingw32/bin (Or wherever the toolchain binaries are)

Linux to Windows x64 cross-compile helper script (Original Readme)

This script automatically builds toolchain and target library/program without much user interaction.

See ./cross_compiler.py list -p and ./cross_compiler.py list -d for a full list of packages.

Install

Clone the repository:

git clone "https://github.com/DeadSix27/python_cross_compile_script.git"
chmod u+x python_cross_compile_script/cross_compiler.py

Usage

Simple usage: ./cross_compiler.py -p <product> (e.g mpv)

For more see: ./cross_compiler.py --help

System requirements:

• Python 3.4+ (Tested only on 3.6.x)
  • Required python packages: requests, progressbar2
• GNU/Linux (Tested on ArchLinux & Ubuntu 17+)
• 20+GB is recommended, but sizes vary depending on the packages
• Resulting binaries support Win7 and newer, 64bit only
