汇总
结构体
| 名称 | 描述 |
|---|---|
| OH_OnFrameAvailableListener | 一个OH_NativeImage的监听者，通过OH_NativeImage_SetOnFrameAvailableListener接口注册， 该监听结构体当有帧可用时，将触发回调 |
类型定义
| 名称 | 描述 |
|---|---|
| OH_NativeImage | 提供OH_NativeImage结构体声明 |
| OHNativeWindow | 提供对NativeWindow的访问功能 |
| OH_OnFrameAvailable | 有buffer可获取时触发的回调函数 |
| OH_OnFrameAvailableListener | 一个OH_NativeImage的监听者，通过OH_NativeImage_SetOnFrameAvailableListener接口注册， 该监听结构体当有帧可用时，将触发回调 |
函数
| 名称 | 描述 |
|---|---|
| OH_NativeImage_Create (uint32_t textureId, uint32_t textureTarget) | 创建一个OH_NativeImage实例，该实例与OpenGL ES的纹理ID和纹理目标相关联 |
| OH_NativeImage_AcquireNativeWindow (OH_NativeImage *image) | 获取与OH_NativeImage相关联的OHNativeWindow指针。该OHNativeWindow后续不再需要时需要调用 OH_NativeWindow_DestroyNativeWindow释放 |
| OH_NativeImage_AttachContext (OH_NativeImage *image, uint32_t textureId) | 将OH_NativeImage实例附加到当前OpenGL ES上下文, 且该OpenGL ES纹理会绑定到 GL_TEXTURE_EXTERNAL_OES, 并通过OH_NativeImage进行更新 |
| OH_NativeImage_DetachContext (OH_NativeImage *image) | 将OH_NativeImage实例从当前OpenGL ES上下文分离 |
| OH_NativeImage_UpdateSurfaceImage (OH_NativeImage *image) | 通过OH_NativeImage获取最新帧更新相关联的OpenGL ES纹理 |
| OH_NativeImage_GetTimestamp (OH_NativeImage *image) | 获取最近调用OH_NativeImage_UpdateSurfaceImage的纹理图像的相关时间戳 |
| OH_NativeImage_GetTransformMatrix (OH_NativeImage *image, float matrix[16]) | 获取最近调用OH_NativeImage_UpdateSurfaceImage的纹理图像的变化矩阵 |
| OH_NativeImage_GetSurfaceId (OH_NativeImage *image, uint64_t *surfaceId) | 获取OH_NativeImage的surface编号 |
| OH_NativeImage_SetOnFrameAvailableListener (OH_NativeImage *image, OH_OnFrameAvailableListener listener) | 设置帧可用回调 |
| OH_NativeImage_UnsetOnFrameAvailableListener (OH_NativeImage *image) | 取消设置帧可用回调 |
| OH_NativeImage_Destroy (OH_NativeImage **image) | 销毁通过OH_NativeImage_Create创建的OH_NativeImage实例, 销毁后该OH_NativeImage指针会被赋值为空 |
