Legendas

Extraia legendas e closed captions do YouTube por ID do vídeo, com idioma configurável e origem das legendas (auto-gerada ou fornecida pelo uploader).

Você pode obter legendas e closed captions (CC) do YouTube fornecendo o ID de vídeo do YouTube e um language_code para o youtube_subtitles source.

Legendas (closed captions) são diferentes de transcrições. Para extrair transcrições padrão, use o YouTube Transcript source.

Exemplos de requisição

O exemplo a seguir demonstra como recuperar closed captions em inglês de um vídeo do YouTube onde as legendas foram fornecidas pelo carregador.
