                              video_ids [video_ids ...]

This is a python API which allows you to get the transcripts/subtitles for a given YouTube video.
It also works for automatically generated subtitles and it does not require a headless browser,
like other selenium based solutions do!

positional arguments:
  video_ids             List of YouTube video IDs.

options:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  --list-transcripts    This will list the languages in which the given videos are available in.
  --languages [LANGUAGES ...]
                        A list of language codes in a descending priority. For example, if this is
                        set to "de en" it will first try to fetch the german transcript (de) and
                        then fetch the english transcript (en) if it fails to do so. As I can't
                        provide a complete list of all working language codes with full certainty,
                        you may have to play around with the language codes a bit, to find the one
                        which is working for you!
  --exclude-generated   If this flag is set transcripts which have been generated by YouTube will
                        not be retrieved.
  --exclude-manually-created
                        If this flag is set transcripts which have been manually created will not
                        be retrieved.
  --format {json,pretty,text,webvtt,srt}
  --translate TRANSLATE
                        The language code for the language you want this transcript to be
                        translated to. Use the --list-transcripts feature to find out which
                        languages are translatable and which translation languages are available.
