#react #antd #video.js #hsl #m3u8

react 中使用 video.js 播放 hls(m3u8)格式的视频

简介：公司业务需求，由于后端把 mp4 视频转码成 m3u8 视频供手机端播放，导致后台系统播放不了 m3u8 格式的视频(原来是直接用的原生 video 标签播放)。

项目主要依赖：（先安装，步骤略）

import VideoPlayer from '@/components/VideoPlayer'
3

5
class AppForm extends Component {
6
  state = {
7
    videoUrl: ""
8
  };
9
10
  componentDidMount() {
11
    this.getVideoUrl();
12
  }
13
14
  // 获取VideoUrl
15
  getVideoUrl = async () => {
16
    let videoUrl =
17
      "https://cn7.kankia.com/hls/20191215/f0bdccd9d46df8600c445e8c6b0c3169/1576378697/index.m3u8";
18
19
    this.setState({ videoUrl });
20
  };
21
22
  render() {
23
    const { videoUrl } = this.state;
24
25
    return <VideoPlayer src={videoUrl} />;

  }
