✨ feat: 添加 ffmpeg 解码器以支持更多音频格式 by apoint123 · Pull Request #716 · imsyy/SPlayer
Summary of Changes
Hello @apoint123, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
此拉取请求旨在通过集成 FFmpeg WebAssembly (WASM) 解码器来增强 SPlayer 的音频播放能力。这一改进将使播放器能够解析和播放更多种类的音频格式。核心实现包括一个新的 FFmpegAudioPlayer 类，它利用 Web Audio API 进行音频输出，并通过 Web Worker 异步处理 FFmpeg 解码，从而提供更稳定和高效的音频体验。
Highlights
- FFmpeg WASM 解码器集成: 为 SPlayer 引入了基于 FFmpeg WebAssembly (WASM) 的音频解码器，以支持更广泛的音频格式。
- 新的音频播放器类: 新增了
FFmpegAudioPlayer类，负责管理音频播放逻辑、Web Audio API 集成、与 Worker 的通信以及音频缓冲流控制。 - Worker 线程解码: 通过 Web Worker 实现了音频解码，将耗时操作从主线程中分离，确保用户界面的流畅性。
- 类型定义更新: 添加了新的 TypeScript 类型定义文件，用于规范播放器状态、音频元数据、Worker 请求/响应以及 FFmpeg WASM 模块的接口。
- 项目结构调整: 为了避免复杂的 C++ 编译流程，直接将相关的 TypeScript 源代码从
apoint123/ffmpeg-audio-player仓库复制过来。
