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 WindowsCreateProcess()
to create child process, the MinGW version just usessystem()
to run the command line. And in theory, as when usingfork()
it useswaitpid()
to wait the process finish, andWaitForSingleObject()
withCreateProcess()
, the main process is always waiting for the child process. So why not just usesystem()
? -
Use Windows CLI
where
to detect FFmpeg, thoughtwhich
still works in MinGW, it doesn't work with CMD or PowerShell. If you want to use the code on *nix, change them back towhich 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.
yaourt
withyaourt -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

Compile & Build
If you want to use the code on *nix, change
where /q ffmpeg
back towhich 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.
