Metadata and Detection Issues ​

Problems with episode/anime detection in batches.

How Name Resolution Works ​

Batches contain files with names like:

[GroupName] Show Name - 05 [1080p][HEVC].mkv

Hayase needs to:

  1. Parse the filename
  2. Extract episode number
  3. Match to correct metadata (title, description, thumbnail)
  4. Display in a user-friendly way

Pattern Matching ​

Hayase looks for episode numbers using various patterns:

  • "05", "E05", "S01E05", "- 05 -"
  • Handles various naming conventions
  • Works with most standard releases

Wrong Episode Detected ​

Non-Standard Numbering ​

Example:

Batch contains:
  - Episode 00 (Special).mkv
  - Episode 01.mkv
  - Episode 02.mkv
  
Hayase might:
  - Skip Episode 00
  - Map Episode 01 to metadata Episode 00
  - Everything off by one

Solution: Find better-named torrent.

Multiple Seasons in One Batch ​

Example:

Batch contains:
  Season 1/
    - Episode 01-12.mkv
  Season 2/
    - Episode 01-12.mkv
    
Hayase might:
  - Lose season distinction

Solution: Use single-season torrents instead.

OVAs and Specials ​

Example:

Batch contains:
  - Episodes 01-12.mkv
  - OVA 1.mkv
  - OVA 2.mkv
  - Special.mkv
  
Hayase might:
  - Not recognize OVAs
  - Place them incorrectly
  - Show wrong metadata

Solution: Find separate torrents for OVAs or manually browse video files:

  • In the player UI open the options menu [...] and select Playlist
  • Select correct file by actual filename

Files Named by Title (No Numbers) ​

Example:

Files named by title instead of number:
  "The First Episode.mkv"
  "The Second Episode.mkv"

Detection relies on alphabetical order
May fail completely

Solution: Find properly numbered torrents.

Wrong Anime Detected ​

Why it happens:

  • Torrent name is ambiguous
  • Similar show names exist
  • Metadata API confusion
  • Old vs new anime with same name

Example:

Torrent: "Fullmetal Alchemist"
Could be:
- Fullmetal Alchemist (2003)
- Fullmetal Alchemist: Brotherhood (2009)

Hayase might pick wrong one

Solution: Manually select the correct anime from search or override detection:

  • In the player UI open the options menu [...] and select Playlist
  • Select correct file by name

Multiple Shows in One Batch ​

Example:

Torrent: "Fall 2024 Anime Collection"
Contains multiple different shows
  
Hayase will:
  - Try to match all to one series
  - Completely fail
  - Show wrong metadata for everything

Solution: Avoid mixed-content batches. Download individual show torrents instead.

When Detection Fails ​

Symptoms:

  • Wrong episode numbers displayed
  • Episodes out of order
  • Missing episodes
  • Wrong anime metadata shown

What Hayase does:

  • Shows files in alphabetical order
  • Lets you access files directly

What you can do:

  • Manually browse torrent files
    • In the player UI open the options menu [...] and select Playlist
    • Select correct file by name
  • Check actual filenames to identify correct episodes
  • Report problematic releases to improve detection
  • Find better-named torrents

"Wrong episode playing" ​

Cause: Filename parsing failed

Solution:

  • Manually browse torrent files
    • In the player UI open the options menu [...] and select Playlist
    • Select correct file by name
  • Report the issue for improvement
  • Batch doesn't actually contain the episode

Possible causes:

  • Batch doesn't actually contain them
  • Detection skipped special episodes
  • Files hidden in subdirectories

Solution:

  • Check torrent file list
  • Browse files directly
  • Verify batch contents before downloading by reading file name
