将 实时流 转换为 m3u8文件#

ffmpeg -i rtsp://192.168.1.19:554/channel=0,stream=0 -c copy -f hls -hls_time 10 -hls_list_size 0 -hls_segment_filename saved_%5d.ts index.m3u8

前端视频插件hls.js#

前端实现播放实时监控视频笔记(hls http-flv)

<script >
import Hls from 'hls.js'

export default {


  methods: {

    switchHlsvideo: function () {
      const video = document.getElementById('video')
      const url = 'http://localhost:8089/download/index.m3u8' // 直播视频源（.m3u8）文件地址
      if (Hls.isSupported()) {
        // 如果支持 hls.js（MediaSource Extensions）
        var hls = new Hls()
        hls.loadSource(url)
        hls.attachMedia(video)
        // 自动播放
        hls.on(Hls.Events.MANIFEST_PARSED, function () {
          video.play()
        })
      } else if (video.canPlayType('application/vnd.apple.mpegurl')) {
        // 如果支持原生播放
        video.src = url
        // 自动播放
        video.addEventListener('canplay', function () {
          video.play()
        })
      }
    },
    switchvideo: function () {
      var player = videojs('example-video');
      //player.play();
      //切换视频
      function switchvideo() {
        player.src({
          src: '"http://localhost:8089/download/index.m3u8"',
          type: 'application/x-mpegURL',
