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.
