 * __AUDIO_DOWNLOAD_DIR__: path to where audio-only downloads will be saved, if you wish to separate them from the video downloads. Defaults to the value of `DOWNLOAD_DIR`.

 * __URL_PREFIX__: base path for the web server (for use when hosting behind a reverse proxy). Defaults to `/`.

 * __OUTPUT_TEMPLATE__: the template for the filenames of the downloaded videos, formatted according to [this spec](https://github.com/ytdl-org/youtube-dl/blob/master/README.md#output-template). Defaults to `%(title)s.%(ext)s`.

+* __YTDL_OPTIONS__: Additional options to pass to youtube-dl, in JSON format. [See available options here](https://github.com/yt-dlp/yt-dlp/blob/master/yt_dlp/YoutubeDL.py#L176). They roughly correspond to command-line options, though some do not have exact equivalents here, for example `--recode-video` has to be specified via `postprocessors`. Also note that dashes are replaced with underscores. Example value: `{"sleep_interval":10}`.
