Mimi Downloader

English/English

Bilibili video and barrage downloader developed based on Node.js and Electron.

Function

Features currently implemented:

• Query video details and obtain video download address based on video URL
• Obtain the content of the video barrage based on the video cid and support conversion to download format ( .xml or .ass )
• Download video and audio files (formats are .mp4 and .m4a respectively), support resumable download

Current limitations:

• Due to Bilibili restrictions, only low-definition videos can be obtained without logging in
• The downloaded video and audio are separate files and need to be merged manually using tools such as ffmpeg

How to use

You need to install Git and Node.js (and npm) to run this program.
An important dependency of this program is Electron. If your network environment is restricted, please set the following environment variables first, and then execute the following commands to install it through the mirror:

 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

Enter at the command line:

 # 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

If everything goes well, a new window named "Mimi Downloader" will open. Enter the video link (for example https://www.bilibili.com/video/BV1z4411p7Lq) and follow the prompts to download the video.

Once the download is complete, you can use ffmpeg to merge the video and audio into a single file:

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