UClASS() 宏 和GENERATED_UCLASS_BODY() 有什么区别 GENERATED_UCLASS_BODY() ：必须要在CPP声明构造函数 否则会导致编译出现问题

OPENGL + FFMPEG 实现全景播放器 加载并编译着色器，用于处理顶点和片段着色。 创建一个球体模型，用于映射视频帧。 实现渲染帧的功能，将解码后的帧数据传递给GPU并绘制在球体上 Video 视频处理 编解码闪屏问题每次渲染新帧时，屏幕可能会出现闪屏现象，这可能是渲染的帧没有正确地显示或者上一帧的内容在新帧显示之前被清空。启用了VSync（垂直同步）。VSync会使得帧刷新率与显示器的刷新率同步，避免在图像未完全刷新时就进行绘制，从而减少闪屏和撕裂的情况。 双缓存问题启用双缓冲机制。这会使得渲染完成的一帧不会立即显示，而是先保存在一个缓冲区中，直到当前帧全部渲染完成后再交换缓冲区，避免屏幕上出现不完整的图像。 1glfwWindowHint(GLFW_DOUBLEBUFFER, GL_TRUE); 多线程处理，其中一个线程专门负责视频解码和帧数据准备，而主线程只负责渲染。这种方法有效地避免了主线程因为解码而阻塞导致的渲染延迟，从而消除了闪屏问题。 123456789101112131415161718192021222324252627// 解码线程，负责解码视频帧vo ...

Binary Search Problem Set1. Template Binary Search ProblemsThese are the classic binary search applications, usually searching directly in arrays or matrices. 704. Binary Search Given a sorted array of integers and a target value, return the index if the target is found. If not, return -1. 702. Search in a Sorted Array of Unknown Size You are given an array-like data structure with get(index) API but you don’t know the size. Find the target in this sorted structure with minimal calls to get. 74 ...

Traversal (遍历型递归)144. Binary Tree Preorder TraversalDescription: Return the preorder traversal of a binary tree (Root → Left → Right). Interview Thought: Think “when I arrive at this node, what should I record?” Maintain a result list. Preorder means process root first, then recurse left, then right. Traversal template applies directly. 94. Binary Tree Inorder TraversalDescription: Return the inorder traversal of a binary tree (Left → Root → Right). Interview Thought: Standard DFS order problem ...
