AndroidVideoCache
AndroidVideoCache 是一个用于 Android 的本地代理服务器和基于磁盘的媒体缓存。它拦截网络请求以将流式视频数据存储在本地文件系统上，从而实现离线播放并减少数据使用。
该项目通过作为可以注入自定义请求头的 HTTP 代理缓存而脱颖而出。这使得能够在缓存过程中通过满足服务器端安全和认证要求来交付经过认证的视频内容。
该系统通过字节级磁盘缓存、URL 到文件映射以及使用最近最少使用（LRU）驱逐策略强制执行存储配额来管理存储。它还包括用于跟踪缓存进度和可定制文件命名逻辑以防止冲突的实用工具。
Features
- Proxy Servers - Functions as a local HTTP proxy server that intercepts video requests to manage data retrieval and disk caching.
- Disk-Backed Implementations - Implements a disk-backed cache that stores streaming video data in chunks to enable playback without redundant network requests.
- Video Content Caching - Stores streamed video data on the local disk to enable play-while-cache functionality and offline access.
- Local Disk Caching - Implements a disk-based cache that saves remote video streams to local files to prevent redundant network requests.
- Media Proxy Caching - Provides a local proxy server that intercepts media network traffic to cache video data on disk.
- Authentication Header Injection - Provides mechanisms to inject session cookies and authentication tokens into outbound HTTP requests to access secured video streams.
- Cache Storage Quotas - Enforces disk storage quotas to cap the total space used for caching video content.
- HTTP Stream Piping - Pipes HTTP response streams directly to the video player while simultaneously persisting the data to the local disk.
- Streaming Optimizations - Optimizes mobile video streaming by reducing bandwidth and buffering through a local proxy cache.
- Cache Proxies - Functions as a cache proxy that intercepts network requests to store video content and inject authentication headers.
- Subscription Content Authentication - Handles credential-based access to restricted media streams by injecting custom authentication headers during the caching process.
- Disk-Backed LRU Evictions - Automatically removes the least-recently-used cached video files when the defined disk storage limit is reached.
