+## OpenFX Support TODO
+- Implement plugin discovery/loading from a given path and populate the cache (currently creates host/cache only). `app/pluginSupport/OliveHost.cpp`
+- Wire output clip image storage: allocate a backing buffer, set `kOfxImagePropData`, and update bounds/rowBytes before render. `app/pluginSupport/OliveClip.cpp`
+- Provide real input clip image fetches (currently returns an empty `Image` for inputs). `app/pluginSupport/OliveClip.cpp`
+- Ensure render path sets per-frame output data and handles ROD/bounds correctly. `app/render/plugin/pluginrenderer.cpp`
+- Add missing param instance types (String, Double3D/Integer3D, Group/Page, Custom/Bytes) and mapping to node inputs. `app/pluginSupport/OlivePluginInstance.cpp`, `app/node/plugins/Plugin.cpp`
+- Implement `editBegin`/`editEnd`, progress, and timeline hooks instead of stubs. `app/pluginSupport/OlivePluginInstance.cpp`, `app/pluginSupport/OlivePluginInstance.h`
+- Integrate persistent message handling with the app UI (currently TODO placeholders). `app/pluginSupport/OlivePluginInstance.cpp`
+- Decide and enforce project extent/fielding behavior instead of the current placeholder comment. `app/pluginSupport/OlivePluginInstance.cpp`
+- Add OpenGL texture render suite support or explicitly disable it (currently `loadTexture` returns null). `app/pluginSupport/OliveClip.h`

+# OpenFX 支持 TODO（中文说明）
+
+下面是 README 里 OpenFX TODO 的中文翻译与详细说明。每条都尽量解释“是什么、为什么需要、该往哪里改”。
+
+1) 实现插件发现与加载流程
+- 现状：`app/pluginSupport/OliveHost.cpp` 里只创建了 Host 和 PluginCache，但没有扫描路径/加载 OFX 插件。
+- 为什么需要：没有完整的发现/加载，就无法让用户看到插件或实例化插件。
+- 可能改动：补全 `loadPlugins()`，遍历指定目录（如 OFX 标准路径），调用 OpenFX 的插件缓存加载逻辑，注册可用插件并让 UI/节点系统可用。
+
+2) 输出剪辑图像的缓冲区管理（Output Clip）
+- 现状：`OliveClipInstance::getImage()` 返回空的 OFX Image，没有分配像素内存，也没有设置 `kOfxImagePropData`。
+- 为什么需要：插件渲染时会往 `kOfxImagePropData` 写入像素，如果这里没分配就会导致崩溃或黑屏。
+- 可能改动：为 Output Clip 分配像素缓冲（例如 `std::vector<uint8_t>`），填充 `kOfxImagePropData`、`kOfxImagePropRowBytes`、`kOfxImagePropBounds`，并保证生命周期覆盖渲染过程。
+
+3) 输入剪辑图像的拉取（Input Clip Fetch）
+- 现状：`OliveClipInstance::getImage()` 对输入剪辑直接返回一个空 Image，没有真正把输入帧填进去。
+- 为什么需要：多数插件需要输入图像做处理，没有输入就无法正确工作。
+- 可能改动：根据当前时间 `time` 从渲染管线/缓存/纹理中取出输入帧，设置 OFX Image 的 data/bounds/rowBytes 等属性并返回。
+
+4) 渲染路径中设置每帧输出数据与 ROD/Bounds
+- 现状：`app/render/plugin/pluginrenderer.cpp` 中已接了 Image->AVFrame，但仍需要保证每帧输出图像属性正确（ROD/Bounds）。
+- 为什么需要：插件对 ROD 和 bounds 非常敏感，用错会导致裁剪错误或错位。
+- 可能改动：在渲染前或 render action 前，按当前时间/ROI 计算并设置 Output Clip 的 `kOfxImagePropBounds`、`kOfxImagePropRegionOfDefinition` 等。
+
+5) 参数类型支持不完整（Param Instances）
+- 现状：`OlivePluginInstance::newParam()` 只支持少量类型，`app/node/plugins/Plugin.cpp` 里也没有处理 Group/Page 等。
+- 为什么需要：复杂插件大量依赖 String/3D/Custom 等参数，不支持就会缺参数或崩溃。
+- 可能改动：补齐 String、Double3D/Integer3D、Group/Page、Custom/Bytes 等参数实例，并在节点输入映射里增加对应类型。
+
+6) editBegin/editEnd、Progress、Timeline 等回调还只是空实现
+- 现状：`OlivePluginInstance` 中多处函数是空壳或默认返回。
+- 为什么需要：插件在编辑参数、显示进度、根据时间线上下文渲染时依赖这些回调。
+- 可能改动：实现 editBegin/editEnd 通知；progressStart/Update/End 与 UI 进度条连接；timelineGetTime/GotoTime/Bounds 与工程时间轴连接。
+
+8) Project Extent / Fielding 行为待确认
+- 现状：`OlivePluginInstance::getProjectExtent()` 有 “TODO” 注释。
+- 为什么需要：OFX 插件会根据项目尺寸、扫描线场信息做渲染决策。
+- 可能改动：明确工程是否支持不同 extent/fielding，确保返回值与项目设置一致。
+
+9) OpenGL Render Suite 支持
+- 现状：`OliveClipInstance::loadTexture()` 返回 null，OpenGL 渲染路径未实现。
+- 为什么需要：有些 OFX 插件只支持 OpenGL 渲染，不支持 CPU 渲染。
+- 可能改动：要么实现 OpenGL texture 的加载与生命周期，要么在 host capability 中明确禁用 OpenGL render。
+
+---
+
+如果你希望，我可以把这些 TODO 拆成“优先级 + 预计工作量 + 依赖关系”的形式，方便你逐条推进。
