An elixir library for fetching Youtube Captions without API key. Uses Req under the hood.

The package can be installed by adding youtube_captions to your list of dependencies in mix.exs:

def deps do
  [
    {:youtube_captions, "~> 0.1.0"}
  ]
end

And run mix deps.get.

First find video identifier. You can find it in the YouTube URL ?v=VIDEO_ID.

Then you can download captions by calling YoutubeCaptions.get_subtitles(video_id, language). Language is optional and defaults to en.

If successfull, you'll get list of subtitles in format %{start: float(), duration: float(), text: String.t()}

YoutubeCaptions.get_subtitles("JvBT4XBdoUE", "en")

#=> {:ok,
#=>   [
#=>     %{start: 0.99, text: "[Music]", duration: 6.87},
#=>     %{start: 14.42, text: "thank you so hello everyone and thank", duration: 3.66},
#=>     ...
#=>   ]}

# You can customize Req options by passing third parameter
YoutubeCaptions.get_subtitles("JvBT4XBdoUE", "en", receive_timeout: 10_000)

Heavily inspired by youtube-captions-scraper.
