vue2获取视频时长

1. 使用HTML5的video标签和JavaScript：

   <template>
     <video ref="video" autoplay controls loop muted @loadedmetadata="getVideoDuration">
       <source src="https://desktop-yikao.oss-cn-beijing.aliyuncs.com/avatar/kaissp.mp4" type="video/mp4">
     </video>
   </template>
    
   <script>
   export default {
     methods: {
       getVideoDuration() {
         const videoElement = this.$refs.video;
         const duration = videoElement.duration;
         console.log(duration);
       }
     }
   }
   </script>

2. 使用Vue的@load事件：

   <template>
     <video ref="video" @load="getVideoDuration" :src="videoSource"></video>
   </template>
    
   <script>
   export default {
     data() {
       return {
         videoSource: "your_video_source",
       };
     },
     methods: {
       getVideoDuration() {
         const videoElement = this.$refs.video;
         const duration = videoElement.duration;
         console.log(duration);
       }
     }
   }
   </script>

3. 使用第三方库，如video.js：

   <template>
     <video ref="video" class="video-js"></video>
   </template>
    
   <script>
   import videojs from "video.js";
   import "video.js/dist/video-js.css";
    
   export default {
     mounted() {
       this.initVideoPlayer();
     },
     methods: {
       initVideoPlayer() {
         const videoElement = this.$refs.video;
         const player = videojs(videoElement);
         
         player.on("loadedmetadata", () => {
           const duration = player.duration();
           console.log(duration);
         });
         
         player.src("your_video_source");
       }
     }
   }
   </script>
