The changes made on this fork has been merged to original repo, so you can compile it directly, check it out at moeoverflow/animeloop-cli.

animeloop-cli

Animeloop command line tool. The goal of this project is to automatically find and cut out the looping fragments in Japanese anime. For details, please see my technical report(English), technical report(Chinese).

This is an unoffical MSVC port.

Note for MSVC version

Why?

As I need animeloop-cli to run on Windows, so I tried to build it by myself.

Unfortunately, when I built it with MinGW under MSYS2, GCC couldn't compile child_process.cpp, as it uses fork() that only works on POSIX (or say *nix).

Then I tried to build it with MSYS under MSYS2, which is an Cygwin port -- which simulates POSIX functions -- after resolving linking problems, it compiles successfully, but when it runs, it shows runtime error while loading shared libraries: ?, and I don't know what is ?.

Then I tried Cygwin, after grabbing all the dependencies with the messy installer (sorry but I think package manager like apt or pacman is better) and start to compile, it shows some compile target errors, and I'm not sure what's up.

So I gave it up, and made a Microsoft Visual C++ port.

What's changed?

• Instead of using POSIX fork(), it uses Windows CreateProcess() to create child process, so it's not available to build on *nix.

• Use Windows CLI where to detect FFmpeg.

• Show FFmpeg convert status when resizing video.

How to build?

Checkout Installation section, the Windows steps are appended after Arch Linux (and you won't like it).

Or you can download the binary built by myself from GitHub release page.

Installation

Install via Arch Linux User Repository (aur)

This is the original release, not the MSVC one.

with yaourt

yaourt -S animeloop-cli

Download prebuilt binary for Windows

Checkout GitHub release page, and download FFmpeg 3.x binary from https://ffmpeg.zeranoe.com/ or build FFmpeg by yourself.

Install manually

Modules Init

git submodule init
git submodule update

Dependencies

macOS

Not supported for this fork (except Visual Studio for macOS does some trick to support Windows API?)

Debian/Ubuntu

Not supported for this fork, but you can cross compile it with MinGW.

Arch Linux

Not supported for this fork, but you can cross compile it with MinGW.

Windows MinGW

# - Assume you're building to mingw64, if you'd like to build to mingw32, replace `mingw-w64-x86_64` with `mingw-w64-i686`
#
# - Some packages are updated and not compatible, so some of the steps are using `pacman -U` to install specific version 
#   packages with USTC Mirrors, you can change `https://mirrors.ustc.edu.cn/msys2/mingw/x86_64/` to other sources.

# Build deps
pacman -S libintl mingw-w64-x86_64-gcc mingw-w64-x86_64-cmake

# Boost
# - It seems that when using Boost 1.66+ will cause build fail
pacman -U https://mirrors.ustc.edu.cn/msys2/mingw/x86_64/mingw-w64-x86_64-boost-1.64.0-3-any.pkg.tar.xz

# OpenCV
pacman -U https://mirrors.ustc.edu.cn/msys2/mingw/x86_64/mingw-w64-x86_64-opencv-3.4.3-2-any.pkg.tar.xz
pacman -S mingw-w64-x86_64-hdf5

# Jsoncpp
# - JSONCPP comes with cmake, so if you've install cmake manually, you're not needed to install JSONCPP again
pacman -S mingw-w64-x86_64-jsoncpp

# FFmpeg
# - Some dll files are missing in MSYS2 MinGW64 FFmpeg package, so you should download it from other builds
# - You can also download it later, as it's not build dependency (but runtime dependency)
# pacman -U https://mirrors.ustc.edu.cn/msys2/mingw/x86_64/mingw-w64-x86_64-ffmpeg-3.4.2-1-any.pkg.tar.xz
wget https://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-3.4.2-win64-static.zip
unzip -p ffmpeg-3.4.2-win64-static.zip ffmpeg-3.4.2-win64-static/bin/ffmpeg.exe > /mingw64/bin/ffmpeg.exe

Windows via Microsoft Visual Studio

• Download and install Microsoft Visual Studio

  Will uses Visual Studio 2015 Enterprise (VC14) as example for below.

• Download CMake-GUI

• Download Boost prebuilt library for VC14

  You may need a older version (< 1.66.0) in case of some unknown bug.

• Download OpenCV prebuilt library for Windows

  OpenCV should be 3.2+ but not 4.x

• Download HDF5 prebuilt library for VC14

  You may need an account to download the file, you can register for free or build your own. If you don't want to install the msi package, run msiexec /a drive:\path\to\file.msi /qb TARGETDIR=drive:\path\to\extract

• Download JSONCPP prebuilt library for VC14

Compile & Build

Xcode

Not supported for this fork

CMake

cd animeloop-cli
mkdir build && cd build
cmake ..
make animeloop-cli

CMake-GUI and Visual Studio

• CMake-GUI

  • Create folder build under animeloop-cli folder as Target folder
  • Set Source and Target folder
  • Click Configure button, select Visual Studio 2015
  • Resolve missing parameters
  • Click Genereate button
  • If everything is okay, open the sln file under build folder

• Visual Studio

  • Select animeloop-cli project, and start building
  • If link directories or include directories specificed in CMake is not included, you should config them manually. Here are my configuration, you can change it to your exact folder:

     Include directories: Y:\opencv\build\include;Y:\hdf5\HDF_Group\HDF5\1.10.5\include;Y:\jsoncpp\include;Y:\boost_1_64_0;$(IncludePath)
     Library directories: Y:\opencv\build\x64\vc14\lib;Y:\hdf5\HDF_Group\HDF5\1.10.5\lib;Y:\jsoncpp\lib;Y:\boost_1_64_0\lib64-msvc-14.0;$(LibraryPath)
    

  • If you got C2001 error or it shows encoding problem, convert all files to UTF-8 with BOM, or set project encoding to Unicode (but may still meet encoding problem when running on some code page like CP936).
