auto_skip_anime_intro

Lua script for auto-skipping anime OP and ED based on chapter lengths. Focused on working in mpv when used as an external player for Stremio on Android.

Auto-skips OP and ED in anime by skipping any chapters that are 88-92 seconds long or that are named "OP", "Opening", "ED", or "Credits". This requires that the chapters be labelled in the video. For anime, based on a small sample, the primary Stremio link (eg, NyaaSi Multi Subs 1080p) had chapters labelled about half the time, so this approach may work about half the time.

We later added additional strings (e.g., "logo", "commercial", "previously"), which may help with skipping chapters in non-anime content.

Set up and use Stremio with mpv

1. Launch Stremio
2. Go to Settings
3. Put a checkmark next to: Always start video in external player. You'll get a Warning message. Tap on OK. Tap on Restart.
4. Go through steps to start streaming an anime preferrably selecting the primary link (usually NyaaSi Multi Subs 1080p)
5. When about to start streaming, you'll be asked to select an app. Choose mpv. You may want to tap on Always if you mainly watch anime.
6. Wait to see if the intro gets skipped. If they don't, this is probably because the anime doesn't have chapters labelled. Tap on the gear at the top-right. If chapters are labelled, you'll be able to tap on Chapters.
7. Try a few anime. At least with recent anime, the auto-skipping should work about half the time because about have of the primary links have chapters labelled.

Steps to Auto-Skip OP and ED in Stremio on Google TV

More or less the same process applies as for Android. However, you'll need to sideload mpv onto your Google TV device. You can find the APKs here. You should try to install the v8a-release APK first. If that doesn't work, try the v7a-release APK.

Unfortunately, mpv may be hit and miss with how well it works on different devices. For instance, on Xiaomi Mi Box S (2nd gen), for it to play smoothly, you may need to disable Hardware decoding and possibly enable Reduced quality settings.
