|

// 全屏视频适配经验总结（踩坑记录，避免后续重复犯错）
|
||
// ============================================================
|
||
// 目标：完整显示视频、不变形；在不同设备宽高比下都让视频占屏幕比例最大化。
|
||
//
|
||
// 1. UI 节点角色（场景已配置）：
|
||
// - portraitFullImage：未旋转的 RawImage，专门用于竖屏视频
|
||
// - fullImage：旋转了 -90° 的 RawImage，专门用于横屏视频（让 app 不旋转也能看横屏视频）
|
||
// - 选择规则：video 高>宽 → portraitFullImage；否则 → fullImage
|
||
//
|
||
// 2. 视觉屏幕 = 父 stretch 节点的实际 rect（手机屏幕真实宽高），
|
||
// 与子节点是否旋转无关。RectTransform 的 sizeDelta 在 UI 旋转 90° 后，
|
||
// (sizeDelta.x, sizeDelta.y) 视觉上变成 (sizeDelta.y, sizeDelta.x)。
|
||
//
|
||
// 3. 视频长边贴齐策略（按视频/屏幕比例选边）：
|
||
// 判定 = 视频短边占屏幕比 = 1/videoAspect vs 屏幕宽高比
|
||
// - 1/videoAspect > 屏幕比 → 视频长边贴屏幕短边（视觉宽=parentW，留黑上下）
|
||
// 例：竖屏手机 750x1624 + 横屏视频 1.78 → 视觉=(750, 1335)，sizeDelta=(1335, 750)
|
||
// - 1/videoAspect < 屏幕比 → 视频长边贴屏幕长边（视觉高=parentH，留黑左右）
|
||
// 例：接近正方形 1179x1600 + 横屏视频 1.78 → 视觉=(900, 1600)，sizeDelta=(1600, 900)
|
||
// - 比例接近时（屏幕接近正方形）走"长边贴长边"，让视频占用面积更大
|
||
//
|
||
// 4. 常见错误：
|
||
// - 用 cover 模式裁切 UV：横屏视频在竖屏手机上会左右被裁，丢失画面
|
||
// - 用 contain 让短边贴齐屏幕短边：在 750x1624 上视频会被压缩成窄长条
|
||
// - frameAspect 写反：rotated90 时应该是 parentW/parentH 还是 parentH/parentW 要分清
|
||
// - 视觉屏幕写成了 rotated90 ? parentH : parentW（错）：视觉屏幕与旋转无关，始终是 parentW x parentH
|
||
//
|
||
// 5. UV 不动：使用 contain 不裁切即可，无需调整 uvRect
|
||
