## Jellyfin 10.8
👉👉👉 [Jellyfin 10.8 Instructions](https://github.com/jumoog/intro-skipper/blob/10.8/README.md)

## System requirements

* Jellyfin 10.9.3 (or newer)
* Jellyfin's [fork](https://github.com/jellyfin/jellyfin-ffmpeg) of `ffmpeg` must be installed, version `6.0.1-5` or newer
  * `jellyfin/jellyfin` 10.9.z container: preinstalled
  * `linuxserver/jellyfin` 10.9.z container: preinstalled
  * Debian Linux based native installs: provided by the `jellyfin-ffmpeg6` package
  * MacOS native installs: build ffmpeg with chromaprint support ([instructions](#installation-instructions-for-macos))

## Detection parameters

Show introductions will be detected if they are:

* Located within the first 25% of an episode or the first 10 minutes, whichever is smaller
* Between 15 seconds and 2 minutes long

Ending credits will be detected if they are shorter than 4 minutes.

These parameters can be configured by opening the plugin settings

## Installation

### Step 1: Install the plugin
1. Add this plugin repository to your server: `https://raw.githubusercontent.com/jumoog/intro-skipper/master/manifest.json`
2. Install the Intro Skipper plugin from the General section
3. Restart Jellyfin
### Step 2: Configure the plugin
4. OPTIONAL: Enable automatic skipping or skip button
    1. Go to Dashboard -> Plugins -> Intro Skipper
    2. Check "Automatically skip intros" or "Show skip intro button" and click Save
5. Go to Dashboard -> Scheduled Tasks -> Analyze Episodes and click the play button
6. After a season has completed analyzing, play some episodes from it and observe the results
    1. Status updates are logged before analyzing each season of a show

## Troubleshooting
#### Scheduled tasks fail instantly
- Verify that Intro Skipper can detect ffmpeg with Chromaprint
    - Dashboard -> Plugins -> Intro Skipper -> Support Bundle Info
- Verify that ffmpeg is installed and detected by jellyfin
    - Dashboard -> Playback -> FFmpeg path
- Verify that Chromaprint is enabled in ffmpeg (`--enable-chromaprint`)

#### Skip button is not visible
- Verify you have successfully completed the scheduled task at least once
- Clear your browser cache and reload the Jellyfin server webpage
- Fix any permission mismatches between the web folder and Jellyfin server

    * <b>Docker -</b> the container is being run as a non-root user while having been built as a root user, causing the web files to be owned by root. To solve this, you can remove any lines like `User: 1000:1000`, `GUID:`, `PID:`, etc. from the jellyfin docker compose file.

    * <b>Install from distro repositories -</b> the jellyfin-server will execute as `jellyfin` user while the web files will be owned by `root`, `www-data`, etc. This can <i>likely</i> be fixed by adding the `jellyfin` user (or whichever user executes the jellyfin server) to the same group that owns the jellyfin-web folders. **You should only do this if they are owned by a group other than root**.
- The official Android and Android TV app do not support the skip button. For these apps, you will need to use the autoskip option. Please note that there is currently an [issue](https://github.com/jumoog/intro-skipper/issues/168) with autoskip not working because the apps never receive the seek command from Jellyfin.
## Installation (MacOS)

1. Build ffmpeg with chromaprint support using brew:
    - macOS 12 or newer can install the [portable jellyfin-ffmpeg](https://github.com/jellyfin/jellyfin-ffmpeg)

```
brew uninstall --force --ignore-dependencies ffmpeg
brew install chromaprint amiaopensource/amiaos/decklinksdk
brew tap homebrew-ffmpeg/ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-chromaprint
brew link --overwrite ffmpeg
```

2. Open ~/.config/jellyfin/encoding.xml and add or edit the following lines
    - Replace [FFMPEG_PATH] with the path returned by `whereis ffmpeg`

```
<EncoderAppPath>[FFMPEG_PATH]</EncoderAppPath>
<EncoderAppPathDisplay>[FFMPEG_PATH]</EncoderAppPathDisplay>
```

4. Follow the [general installation instructions](#installation) above
