bp_audio

bp stands for bilibili ported, but also bai piao.

An out-of-the-box extractor for Bilibili's official FLAC music.

It can download Bilibili-purchased music in SQ (aka lossless) version without an account whatsoever. While downloading, it can also acquire music's metadata, including album art. It can also download the whole menu (aka album) at one time.

Example

With metadata included:

Try running this command on your own computer.

Distribution

You can download the pre-compiled x86_64 (amd64) version here, which should be running without any problem on latest Windows devices. Requests for other versions will likely be ignored due to the reason in License & Disclaimer section, so you will have to compile it by yourself: see Compilation section below.

Compilation

First you'll need Qt framework; Qt Creator is highly suggested.

Next you'll need:

• gumbo-query for HTML DOM parsing.

  Actually I can use regex, but that just makes me an idiot.

• TagLib for audio file metadata.

Then just qmake bp_audio.pro and make, as what you would do for every Qt project.

This is only a proof-of-concept of how bad Bilibili's inner software and web developers are—the mixed use of params in path and query, the useless key validation of CDN, etc. Therefore, it shall only be used for research and educational purpose.
