Bilibili Extract Audio

Extracts audio (including music and other permitted audio) from a Bilibili video the user has the right to access and save, given a BV ID or bilibili.com/b23.tv URL. Use when the user asks to save, convert, or extract Bilibili audio as MP3, M4A, OPUS, WAV, or the original stream, including content that may need a logged-in browser session.

Extract Bilibili Audio

Use the bundled CLI. Extract audio from Bilibili videos the user has the right to access and save (permitted audio, music, and similar). Do not bypass access controls.

Run

python scripts/extract_audio.py <BV-or-URL>

Resolve scripts/extract_audio.py relative to this skill directory. Output defaults to ~/Music/Bilibili (override with --output-dir, or BILIBILI_AUDIO_OUTPUT_DIR). Default to the best original audio stream without transcoding. For an M4A source, rewrite only the container as a standard fast-start M4A; preserve the encoded audio bit-for-bit.

Useful options:

--format mp3|m4a|opus|wav|original only when the user requests a specific format
--keep-container to retain Bilibili's original DASH container
--bitrate 192 for converted formats
--cookies-from-browser chrome|edge|firefox only when the user explicitly asks to use an existing logged-in session
--all-parts to process every part of a multipart video

If dependencies are missing:

python -m pip install --user -U yt-dlp imageio-ffmpeg

Report

Return the generated filename(s). Preserve errors from Bilibili or yt-dlp. Explain authentication, region, membership, or removed-video errors without attempting to circumvent them.
