Description

Analyze whether the torrent name is a Movie or TV Episode

Inspired from https://regex101.com/library/yP4bY4 There is two versions, see differences at the bottom

Groups:

  • Title (of the Movie/of the TV Series)
  • Season (if TV Episode)
  • Episode (if TV Episode)
  • Year (if Movie)
  • Name (only in v1, should match the TV Episode title if present)
  • Release name (PROPER, REPACK, LIMITED, etc..)
  • Resolution (720p, 1080p, etc..)
  • Quality (HDTV, BluRay, WebRip, etc..)
  • Codec (Xvid, x265, x264, etc..)
  • Audio coding (AAC, AC3, DTS, etc...)
  • Team (torrent group/team)
  • Extension (mkv, avi, mp4, etc...)

Versions:

  • v1, include the TV Episode title, and have all the groups in a single match, but will misinterpret the "name" and "team" groups if the expected pattern is not respected (see in the test strings/regex rules)
  • v2, does not include "name" group but is more reliable, will ignore unexpected patterns.
