How to use Hls.js with React properly?

问题

我正在使用Hls.js构建一个用于视频播放器的React组件。我正在使用React的Refs,并在渲染后调用useEffect来获取视频元素。问题是我一直在收到一个错误。

以下是您的代码中翻译后的部分:

import Hls from "hls.js";
import { useEffect, useRef } from "react";

export default function VideoPlayer({ data, className = '', ...props }) {
  const videoRef = useRef();

  useEffect(() => {
    const hls = new Hls({
      "debug": true
    });

    if (Hls.isSupported()) {
      hls.log = true;
      hls.loadSource(data.src);
      console.log(videoRef);
      hls.attachMedia(videoRef.current);
      hls.on(Hls.Events.ERROR, (err) => {
        console.log(err);
      });

    } else {
      console.log('load');
    }
  }, [])

  return (
    <video
      ref={videoRef}
      controls
      {...props}
      src={data.src}
      className={className}
    />
  )
}

这是控制台中的输出:

由于Hls.js需要在渲染后加载,我使用了useEffect,但仍然遇到了问题。我已经检查了其他建议,但问题仍然存在。

如何在React中使用hls.js

英文:

I am building a react for a video player using Hls.js. I am using React Refs and calling useEffect to get the video element after it is rendard. The issue is I keep getting an error.

import Hls from &quot;hls.js&quot;;
import { useEffect, useRef } from &quot;react&quot;;

export default function VideoPlayer({ data, className = &#39;&#39;, ...props }) {
  const videoRef = useRef();

  useEffect(()=&gt;{
    const hls = new Hls({
      &quot;debug&quot;: true
    });

    if (Hls.isSupported()) {
      hls.log = true;
      hls.loadSource = data.src;
      console.log(videoRef)
      hls.attachMedia(videoRef)
      hls.on(Hls.Events.ERROR, (err) =&gt; {
        console.log(err)
      });

    } else {
      console.log(&#39;load&#39;)
    }
  },[])

  return (
    &lt;video
      ref={videoRef}
      controls
      {...props}
      src={data.src}
      className={className}
    /&gt;
  )
}

This is the output I get in the console.

Screenshot of Error in Console

Seeing that the Hls.js needs to load after the redering, I used the useEffect but still have an issue.

I have reviewed the other suggestion already and still have the issue.

我能够找出我的错误。我没有抓取当前 ref。

import Hls from "hls.js";
import { useEffect, useRef } from "react";

export default function VideoPlayer({ data, className = '', ...props }) {
  const videoRef = useRef();

  useEffect(() => {
    const hls = new Hls({
      "debug": true
    });

    if (Hls.isSupported()) {
      hls.log = true;
      hls.loadSource = data.src;
      hls.attachMedia(videoRef.current)
      hls.on(Hls.Events.ERROR, (err) => {
        console.log(err)
      });

    } else {
      console.log('load')
    }
  }, [data])

  return (
    <video
      ref={videoRef}
      controls
      {...props}
      src={data.src}
      className={className}
    />
  )
}

我希望这对其他人有所帮助。这是一个简短的帖子,但在喝咖啡后我能够找出解决方法...

英文:

I was able to figure out my mistake. I wasn't grabbing the current ref

import Hls from &quot;hls.js&quot;;
import { useEffect, useRef } from &quot;react&quot;;

export default function VideoPlayer({ data, className = &#39;&#39;, ...props }) {
  const videoRef = useRef();

  useEffect(()=&gt;{
    const hls = new Hls({
      &quot;debug&quot;: true
    });

    if (Hls.isSupported()) {
      hls.log = true;
      hls.loadSource = data.src;
      hls.attachMedia(videoRef.current)
      hls.on(Hls.Events.ERROR, (err) =&gt; {
        console.log(err)
      });

    } else {
      console.log(&#39;load&#39;)
    }
  },[data])

  return (
    &lt;video
      ref={videoRef}
      controls
      {...props}
      src={data.src}
      className={className}
    /&gt;
  )
}

I hope this helps anyone else. This was a short post but I was able to figure out after making some coffee...
