In case anyone is interested here are RegExp's for:

  • video ID [-_A-Za-z0-9]{10}[AEIMQUYcgkosw048],
  • Channel/Playlist ID [-_A-Za-z0-9]{21}[AQgw].

Source: https://stackoverflow.com/a/41988283/11194000

(However there seem to be more playlist IDs, e.g. 18-char https://www.youtube.com/playlist?list=PL5FCAB5CF67CA3F05 and 34-char https://www.youtube.com/playlist?list=PLfqsGS_H3rpoY0P0-Djkg5QFj676mLRH1).
