FAQ from Bilibili Subtitle Fetch

How do I configure Bilibili credentials?

Run bilibili-subtitle-fetch init and paste your Bilibili cookie. The configuration is saved to ~/.config/bilibili-subtitle-fetch/config.toml (Linux/macOS) or %APPDATA%\bilibili-subtitle-fetch\config.toml (Windows).

What is the ASR fallback feature?

If a video has no built-in subtitles, the server can automatically download the audio and generate subtitles using OpenAI Whisper. This is enabled or disabled via the [asr] config section or the --asr/--no-asr flags.

What output formats are available?

Two formats: text (plain subtitle text) and timestamped (subtitle content with timestamps). The default can be overridden with --output-format.

Can I use a custom configuration file path?

Yes, use the --config /path/to/config.toml argument when running the server or CLI commands.

What dependencies does the server require?

Python 3.13, the uv tool, and optionally Whisper for ASR fallback. A valid Bilibili cookie is required for subtitle access.
