A simple audio player plugin for flutter.

lychee_player's Issues

fix crash when switch player in flutter

参考 Chromium Media Playback 实现

Chromium Media Playback Diagram.

Chromium Media Codebase

计划实现

1. FFmpegDemuxer 负责解复用 Datasource 中的 bytestream, 分别提供 Audio 和 Video 的 Stream.
2. AudioRenderer/VideoRenderer 取得 Stream 后，从 Stream 中读取 compressed audio/video buffer, 提交给 AudioDecoder / VideoDecoder 解码。
3. Renderer 取得解码后的 Frame，并送往对应的 AudioDevice Textures 进行最后的渲染。
4. 使用 MessageLoop 来管理和协同线程任务。

win7 SetThreadDescription 找不到定位 kernel32.dll

使用KernelBase.dll 替换兼容
HMODULE hKernel32 = GetModuleHandleA("KernelBase.dll");

Windows 未实现 UnregisterTexture

lychee_player/windows/lychee_player_plugin.cpp

Lines 43 to 44 in 51bbeb5

	// FIXME unregister texture.
	// texture_registrar_->UnregisterTexture(texture_id_);

Windows 在 UnregisterTexture TextureId 时会出现崩溃。
暂无解决方案，临时注释处理。
