视频流媒体播放时，视频播放器的导航栏

发布于 2025-01-23 21:59:38 字数 7077 浏览 2 评论 0原文

我正在使用Node，express，socket.io和webrtc构建视频聊天应用程序，然后遵循本教程：链接博客

因此，在我的边缘浏览器上，在我启用了应用程序流并激活了网络摄像头之后，我注意到了这一点，我注意到了这一点，我注意到了这一点当我右键单击视频区域（视频元素）并单击显示所有控件时，我发现视频播放器导航栏已倒置。

您是否有关于为什么NA​​V栏为何倒置有任何阐述？ （检查本截图的屏幕截图是否反向导航栏 screenshot 1 1 https://ibb.co/pcpkbr1“ rel =“ nofollow noreferrer”>屏幕截图 2 ）

以下是​​我的代码：

I'm building a video chat application using Node, Express, Socket.io, and WebRTC by following this tutorial: Link blog

So on my edge browser, after i enabled the video stream on my application and my webcam is activated, i noticed that when i right click on the video area (video element) and click on show all controls, i found that video player navigation bar is inverted.

Do you have any explication on why the nav bar is inverted? (check theses screenshots for inversed nav bar screenshot 1 & screenshot 2)

Below are my codes:

您在元素上施加180度旋转（即镜像）
通过使用变换：CSS文件中的rotatey（180DEG），它也旋转控件。
对于WEBRTC使用，解决此问题的常见方法不是使用视频元素的建筑控件。

You are applying a 180 degree rotation to the element (i.e. mirroring it)
by using transform: rotateY(180deg) in your CSS file which also rotates the controls.
For WebRTC usage the common approach to solving this is not to use the build-in controls of the video element.
