Only fetch videos with CC

[KevinColemanInc]

I think yt-dlp fetches all the videos in a channel, then fetches the stats of each video (checking to see if there are captions).

Large channels with single-digit number number of videos with captions are slow to download (and hit api limits).

The (paid and official) YouTube API allows you to retrieve the video IDs with captions in a specific channel.

curl

curl \
  'https://youtube.googleapis.com/youtube/v3/search?channelId=[ChannelID]&part=id&type=video&videoCaption=closedCaption&key=[KEY]' \
  --header 'Accept: application/json' \
  --compressed
