使用 video.js 这个依赖完成浏览器播放视频资源。尝试了一下，常见资源中，除了 AVI 无法正常播放外，mp4、mkv 都能正常播放与快进。
React 稍微简单配置下即可完成视频播

开发

安装依赖

pnpm i video.js

创建一个视频播放上下文文件。用于控制需要播放视频的地址。

并插入视频播放的 modal 组件

'use client'
import createCtx from '@/lib/create-ctx'
import React from 'react'
import VideoModal from '@/components/video-modal/modal'

export const VideoPathContext = createCtx<string>()
export const useVideoPathStore = VideoPathContext.useStore
export const useVideoPathDispatch = VideoPathContext.useDispatch
export const VideoPathProvider: React.FC<React.PropsWithChildren> = ({ children }) => {
  return (
    <VideoPathContext.ContextProvider value="">
      {children}
      <VideoModal />
    </VideoPathContext.ContextProvider>
  )
}

文件路径：src/components/video-modal/modal.tsx

视频播放弹窗，显示条件为是否设置了播放视频地址。

弹窗设置了 destroyOnClose 属性，当弹窗关闭后，销毁弹窗内容。

'use client'
import React from 'react'
import { Modal } from 'antd'
import { isEmpty } from 'lodash'
import VideoJS from '@/components/video-modal/video-js'
import Player from 'video.js/dist/types/player'
import { useVideoPathDispatch, useVideoPathStore } from '@/components/video-modal/video-path-context'

const VideoModal: React.FC = () => {
  const video_path = useVideoPathStore()
  const changeVideoPath = useVideoPathDispatch()
  const filename = decodeURIComponent(video_path).split('/').pop()

  const playerRef = React.useRef<Player | null>(null)

  const videoJsOptions = {
    autoplay: true,
    controls: true,
    responsive: true,
    fluid: true,
    sources: [
      {
        src: video_path,
        type: 'video/mp4',
      },
    ],
  }

  return (
    <Modal
      title={filename}
      open={!isEmpty(video_path)}
      width="75%"
      onCancel={() => changeVideoPath('')}
      footer={false}
      destroyOnClose={true}
    >
      <VideoJS
        options={videoJsOptions}
        onReady={(player) => {
          playerRef.current = player

          player.on('waiting', () => {
            console.log('player is waiting')
          })

          player.on('dispose', () => {
            console.log('player will dispose')
          })
        }}
      />
    </Modal>
  )
}

export default VideoModal

Video.js 组件封装

1. playbackRates 设置了 [0.5, 1, 1.5, 2] 倍数播放
2. 快进 5 秒、快退 5 秒按钮
3. 按下键盘的左右键实现快进一帧、后退一帧。（这里是默认每秒 25 帧计算）
4. 当组件被销毁时，执行 player.dispose() 方法一同销毁播放器

import React, { KeyboardEvent } from 'react'
import videoJs from 'video.js'
import 'video.js/dist/video-js.css'
import './style.css'
import Player from 'video.js/dist/types/player'
import styled from 'styled-components'

const VideoMain = styled.div`
  .video-js {
    padding-top: 70% !important;
  }
`

export const VideoJS: React.FC<{ options: any; onReady: (player: Player) => void }> = (props) => {
  const video_ref = React.useRef<HTMLDivElement>(null)
  const player_ref = React.useRef<Player | null>(null)
  const { options, onReady } = props

  React.useEffect(() => {
    if (!player_ref.current) {
      const videoElement = document.createElement('video-js')

      videoElement.classList.add('vjs-big-play-centered')
      video_ref.current?.appendChild(videoElement)

      const player = (player_ref.current = videoJs(
        videoElement,
        {
          playbackRates: [0.5, 1, 1.5, 2],
          controlBar: {
            skipButtons: {
              forward: 5,
              backward: 5,
            },
          },
          userActions: {
            hotkeys: (event: KeyboardEvent) => {
              if (event.key === 'ArrowLeft') {
                player_ref.current?.pause()
                player_ref.current?.currentTime((player_ref.current?.currentTime() || 0) - 1 / 25)
              }
              if (event.key === 'ArrowRight') {
                player_ref.current?.pause()
                player_ref.current?.currentTime((player_ref.current?.currentTime() || 0) + 1 / 25)
              }
              if (event.key === 'ArrowUp') {
              }
              if (event.key === 'ArrowDown') {
              }
              if (event.key === ' ') {
                if (player_ref.current?.paused()) {
                  player_ref.current?.play()?.then()
                } else {
                  player_ref.current?.pause()
                }
              }
            },
          },
          ...options,
        },
        () => {
          videoJs.log('player is ready')

          onReady && onReady(player)
        },
      ))
    } else {
      const player = player_ref.current

      player.autoplay(options.autoplay)
      player.src(options.sources)
    }
  }, [onReady, options, video_ref])

  React.useEffect(() => {
    const player = player_ref.current

    return () => {
      if (player && !player.isDisposed()) {
        player.dispose()
        player_ref.current = null
      }
    }
  }, [player_ref])

  return (
    <div data-vjs-player={true}>
      <VideoMain ref={video_ref} />
    </div>
  )
}

export default VideoJS

文件路径：src/app/path/context.tsx

最后将 VideoPathProvider 组件插入 src/app/path/context.tsx 内

...
import { VideoPathProvider } from '@/components/video-modal/video-path-context'

export const PathContextProvider: React.FC<React.ProviderProps<ReaddirListType>> = ({ value, children }) => {
  return (
    <>
...
            <VideoPathProvider>{children}</VideoPathProvider>
...
    </>
  )
}

文件路径：src/components/preview/index.tsx

预览文件，对视频的 icon 点击时设置视频播放地址。

...
import { useVideoPathDispatch } from '@/components/video-modal/video-path-context'

const Preview: React.FC<{ item: ReaddirItemType }> = ({ item }) => {
...
  const videoPathDispatch = useVideoPathDispatch()

  if (isVideo(name)) {
    return <VideoCameraOutlined onClick={() => videoPathDispatch(staticPath(name))} />
  }
...
}

export default Preview

到此完成了视频弹窗播放。
