This repository is an Android TV application (役čŚTV) that provides a comprehensive media center experience for streaming Video-on-Demand (VOD) and live television. It features a plugin-based content aggregation system using spiders written in Java, Python (via Chaquopy), and JavaScript (via QuickJS), allowing users to browse and play content from multiple external sources. The application supports multiple player engines (ExoPlayer and mpv), hardware/software decoding, subtitle and danmaku (bullet comment) overlays, DLNA casting (both sender and renderer), and a local HTTP server for remote control and file sharing. Architecturally, the project is a multi-module Gradle build with a shared core library (catvod) providing network utilities, cryptography, and data models. The main app module contains two UI tracks: 'leanback' for TV remote control navigation and 'mobile' for touch-based phone interaction, both sharing common logic under app/src/main. The system uses an event-driven architecture with EventBus, a Room-based SQLite database for persistence, and a ViewModel pattern for reactive UI updates. External content sources are integrated through a standardized Spider interface, with loaders for JAR, Python, and JavaScript plugins. Key features include a sophisticated playback controller with fallback policies, preloading, and history management; extensive audio/video effect pipelines (equalizer, loudness normalization, color adjustment); danmaku search and display; EPG (Electronic Program Guide) with timezone-aware parsing; and a comprehensive settings system covering player, decoding, subtitles, and network configuration. The project also includes a documentation website built with Next.js, providing developer guides for the spider API and local HTTP API.
