2022-12-15 12:01:07

Video.js 是一個具有大量功能的流行的視訊和音訊 JavaScript 庫,今天我們試試整合到 Blazor .

Blazor VideoPlayer 視訊播放器 元件

範例

https://blazor.app1.es/videoPlayers

1. 新建工程b13video

dotnet new blazorserver -o b13video

2. 將專案新增到解決方案中：

dotnet sln add b13video/b13video.csproj

3. Pages\_Host.cshtml 參照 video-js.css

<link href="//vjs.zencdn.net/7.10.2/video-js.min.css" rel="stylesheet">

4. 接下來，Pages\_Host.cshtml 參照 Video.js, 新增以下指令碼檔案到Pages\_Host.cshtml

<script src="https://vjs.zencdn.net/7.10.2/video.js"></script>

<script src="https://unpkg.com/video.js/dist/video.min.js"></script>
<script src="https://unpkg.com/@@videojs/http-streaming/dist/videojs-http-streaming.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/videojs-youtube/2.6.1/Youtube.min.js"></script>

5. 新增 app.js 檔案到 wwwroot資料夾

檔案內容

function loadPlayer(id, options) {
  videojs(id, options);
}

6. Pages\_Host.cshtml 參照 app.js

<script src="./app.js"></script>

完整檔案看起來應該是這樣

@page "/"
@using Microsoft.AspNetCore.Components.Web
@namespace b13video.Pages
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
