Mimi Downloader

英文/English

基于 Node.js 和 Electron 开发的 Bilibili 视频、弹幕下载器。

功能

目前实现的功能:

  • 根据视频 URL 查询视频详细信息并获取视频下载地址
  • 根据视频 cid 获取视频弹幕的内容并支持转换下载格式(.xml.ass
  • 下载视频和音频文件(格式分别为 .mp4.m4a),支持断点续传

目前的局限性:

  • 由于 Bilibili 限制,在未登录情况下只能获得低清晰度视频
  • 下载的视频和音频是分开的文件,需人工使用 ffmpeg 等工具进行合并

使用方法

你需要安装 GitNode.js(以及 npm)来运行本程序。
本程序的一个重要依赖是 Electron,如果你所在的网络环境受到限制,请先设置如下环境变量,再执行后面的命令,以通过镜像安装之:

export ELECTRON_MIRROR="https://npmmirror.com/mirrors/electron/" # 一般的 *NIX 命令行
set ELECTRON_MIRROR=https://npmmirror.com/mirrors/electron/ # 使用 Windows CMD 命令行
$env:ELECTRON_MIRROR="https://npmmirror.com/mirrors/electron/" # Windows PowerShell

在命令行输入:

# 克隆这个仓库
git clone https://github.com/stevenjoezhang/bilibili-downloader.git
# 进入目录
cd bilibili-downloader
# 安装依赖
npm install
# 启动!
npm start

如果一切正常,会打开一个名为「Mimi Downloader」的新窗口。输入视频链接(例如 https://www.bilibili.com/video/BV1z4411p7Lq ),按照提示即可下载视频。

下载完成后,可以使用 ffmpeg 将视频和音频合并为一个文件:

ffmpeg -i input_video.mp4 -i input_audio.m4a -c:v copy -c:a aac output_file.mp4

相关项目

哔哩下载姬及其跨平台版本也是不错的选择,能够在扫码登录后下载高清视频。

如果你需要更为强大的命令行工具,那么以下仓库或许有帮助。如果需要下载高清视频,可能需要手动设置 Cookie。

这里还有一些其它的库和浏览器插件供参考。
