这个 Pull Request 通过集成 FFmpeg wasm 解码器,为 SPlayer 添加了对更多音频格式的支持,这是一个很棒的功能增强。整体实现很不错,通过 Web Worker 进行解码避免了主线程阻塞,代码结构清晰,对 wasm 内存管理也考虑得比较周到。我的审查主要集中在一些可以提升代码健壮性和修复潜在内存泄漏的方面。具体来说,我提出以下建议:
- 修复一个由
URL.createObjectURL引起的内存泄漏问题。 - 建议使用更可靠的方式生成与 Worker 通信的唯一消息 ID。
- 统一错误处理逻辑,并清理了一些冗余代码。
这些修改将有助于提高播放器的稳定性和性能。请查看具体的代码注释。

你好,感谢你的贡献。这次的 Pull Request 是一次重大的重构,通过引入基于 FFmpeg 和 WebAssembly 的新解码器,为播放器增加了对更多音频格式的支持。整体代码结构清晰,通过抽象基类 BaseAudioPlayer 和不同的播放器实现(AudioElementPlayer、FFmpegAudioPlayer)构建了一个灵活的播放器架构,这是非常出色的实践。新的 AudioManager 作为外观(Facade),很好地封装了底层的复杂性。代码在细节处理上也很到位,例如在 FFmpegAudioPlayer 中使用 Web Worker 来处理解码任务,并通过 messageId 来处理过时消息,确保了异步操作的正确性。我为你提供了一些具体的反馈,主要集中在新代码的可维护性和潜在的性能优化上,希望能帮助你进一步完善这次出色的工作。

本次 PR 引入了基于 FFmpeg wasm 的新音频解码器,这是一个非常出色的功能,极大地扩展了应用对音频格式的支持范围。代码重构非常出色,通过引入 BaseAudioPlayer 抽象基类和两个具体的播放器实现(AudioElementPlayer 和 FFmpegAudioPlayer),将音频播放逻辑模块化,遵循了良好的设计模式,显著提高了代码的可维护性和可扩展性。对 Web Worker 的使用以及其中的缓冲和同步机制(如 currentMessageId)处理得非常到位,保证了主线程的流畅运行。整体来看,这是一次高质量、高复杂度的代码提交。我提出了一些小的改进建议,主要集中在提升代码可读性和简化逻辑方面。

为 SPlayer 添加 ffmpeg wasm 解码器以便解析更多的音频格式
相关的源代码位于 https://github.com/apoint123/ffmpeg-audio-player,由于发布并引入一个带有 worker 和 wasm 的库比较困难,我直接将 ts 源代码完整复制过来了,wasm 相关源代码仍然保留在原仓库以避免引入复杂的 C++ 编译流程
