allsubtitles: Downloads all the subtitles of the video
(requires writesubtitles or writeautomaticsub)
listsubtitles: Lists all available subtitles for the video
- subtitlesformat: Subtitle format [srt/sbv/vtt] (default=srt)
+ subtitlesformat: The format code for subtitles
subtitleslangs: List of languages of the subtitles to download
keepvideo: Keep the video file after post-processing
daterange: A DateRange object, download only if the upload_date is in the range.
external_downloader: Executable of the external downloader to call.
listformats: Print an overview of available video formats and exit.
list_thumbnails: Print a table of all thumbnails and exit.
+ match_filter: A function that gets called with the info_dict of
+ every video.
+ If it returns a message, the video is ignored.
+ If it returns None, the video is downloaded.
+ match_filter_func in utils.py is one example for this.
+ no_color: Do not emit color codes in output.
