Bilibili, often referred to as B-station or simply B站, is a popular Chinese video-sharing platform that hosts a wide range of content, including anime, live streams, educational videos, and more. If you’re interested in downloading videos from Bilibili for offline viewing or for other purposes, Python can be a powerful tool to help you achieve this. In this article, we’ll discuss several methods for downloading Bilibili videos using Python, including both manual and automated approaches.
Method 1: Manual Download Using Browser Developer Tools
Before delving into Python scripts, it’s worth noting that some Bilibili videos can be downloaded manually using your web browser’s developer tools. However, this method is often limited to videos that are not protected by DRM (Digital Rights Management) or other anti-download measures.
- Navigate to the Bilibili video you want to download.
- Right-click on the video player and select “Inspect” or “Inspect Element” to open the developer tools.
- Look for the network requests related to the video playback. This can involve filtering by media type or searching for specific file extensions like
.mp4or.flv. - Once you’ve identified the video file’s URL, you can copy it and use a download manager or a simple
curlorwgetcommand in your terminal to download the video.
Method 2: Using Third-Party Libraries and Tools
For more complex downloads or when the manual method is not an option, you can use Python libraries or third-party tools that are specifically designed to download Bilibili videos.

youtube-dl: Although
youtube-dlis primarily known for downloading videos from YouTube, it supports a wide range of video-sharing websites, including Bilibili. Be aware, however, thatyoutube-dlis no longer actively maintained, but you can still find forks and alternatives that are up-to-date.To use
youtube-dlor a similar tool to download a Bilibili video, you’ll typically need to install the tool first (using pip for Python-based tools) and then run a command with the video’s URL as an argument. -
Bilibili Video Downloader Libraries: There are also Python libraries specifically designed for downloading Bilibili videos. These libraries often provide additional features, such as selecting video quality, downloading subtitles, and more.
To use these libraries, you’ll need to install them using pip and then write a Python script that utilizes the library’s API to download the desired videos.
Method 3: Automating the Process with Python
For advanced users who want to automate the download process or download multiple videos at once, writing a custom Python script can be a powerful solution. This approach allows you to customize the download process to your specific needs, such as downloading videos from a playlist, selecting specific video qualities, or handling login credentials for private videos.
When writing a Python script to download Bilibili videos, you’ll likely need to reverse-engineer the Bilibili API (if not using a third-party library) or use existing libraries that abstract away the complexity of dealing with the API directly.
Important Considerations
- Legality and Ethics: Before downloading videos from Bilibili or any other video-sharing platform, ensure that you have the right to do so. Downloading copyrighted content without permission may violate the platform’s terms of service and local laws.
- Anti-Download Measures: Bilibili, like many other video-sharing platforms, employs various anti-download measures to prevent unauthorized downloads. Some videos may be protected by DRM or other technologies that make them difficult or impossible to download.
- Updates and Maintenance: The methods and tools mentioned in this article may become outdated or unsupported over time. Keep an eye out for updates and alternatives to ensure that your download process remains effective.
Conclusion
Downloading videos from Bilibili with Python can be a useful skill for a variety of purposes, from offline viewing to data analysis. Whether you choose to use manual methods, third-party libraries, or write your own custom script, there are several options available to help you achieve your goals. Always remember to respect the copyright of the content you’re downloading and be mindful of the platform’s terms of service.
