Some changes made on this fork and animeloop-cli-msvc 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 MinGW port.

Note for MinGW version

Why?

When I'm working on animeloop-cli-msvc, I stucked in making child_process() works for a while. After using Windows CreateProcess() API, FFmpeg still shows it cannot find the file. For debugging what's up, I tested some tricky ways, including system(). Then when I go to sleep that night, I realized that it maybe possible to use system() in MinGW builds. So I tried it, and it works.

What's changed?

• Instead of POSIX fork() and Windows CreateProcess() to create child process, the MinGW version just uses system() to run the command line. And in theory, as when using fork() it uses waitpid() to wait the process finish, and WaitForSingleObject() with CreateProcess(), the main process is always waiting for the child process. So why not just use system()?

• Use Windows CLI where to detect FFmpeg, thought which still works in MinGW, it doesn't work with CMD or PowerShell. If you want to use the code on *nix, change them back to which ffmpeg &> /dev/null.

• Show FFmpeg convert status when resizing video.

How to build?

Checkout Installation section, the Windows steps are appended after Arch Linux.

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 MinGW 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.

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

Compile & Build

If you want to use the code on *nix, change where /q ffmpeg back to which ffmpeg &> /dev/null, or check out the original repo.

Xcode

Open animeloop-cli.xcodeproj and run it.

(if you compile opencv source code by yourself, you maybe need edit Linked Frameworks and Libraries settings in Xcode project.)

CMake

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

Usage

anime loop video generator.

Usage:
  animeloop [OPTION...]

  -h, --help              Show animeloop help
  -v, --version           Show animeloop version
  -i, --input arg         Input video file path
  -o, --output arg        Output video directory path (default: .)
      --title arg         Title name of the source video (default:
                          <filename>)
  -t, --thread arg        Program run in n threads. (default: <cpu core
                          number>)
      --min-duration arg  Minimum duration (second) of loop video (default:
                          0.6)
      --max-duration arg  Maximum duration (second) of loop video (default:
                          6.0)
      --cover             Output loop video cover image.


# Example
./animeloop-cli -i ~/your-video-file --max-duration 4 --min-duration 1.0 --cover -o ~/Downloads/

You should grab a FFmpeg 3.x binary from https://ffmpeg.zeranoe.com/ to make it works.

You should download OpenH264 1.7.0 library file from https://github.com/cisco/openh264/releases manually.

If you want to use it on Windows, always use backslash to set file path like D:\path\to\video.mp4, even under MSYS2 or Cygwin, or boost cannot find the specific path.
