先将视频转码为ts

ffmpeg -i C:\test\3.rmvb -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls C:\test\a\output.m3u8

后端配置接口

import org.springframework.core.io.Resource;
import org.springframework.core.io.UrlResource;
import org.springframework.http.HttpHeaders;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.net.MalformedURLException;
import java.nio.file.Path;
import java.nio.file.Paths;@RestController
@RequestMapping("/api/video")
public class VideoController4 {private final Path videoStorageLocation = Paths.get("C:\\test\\a");@GetMapping("/stream/{fileName}")public ResponseEntity<Resource> streamVideo(@PathVariable String fileName) {try {Path filePath = this.videoStorageLocation.resolve(fileName).normalize();System.out.println(filePath);Resource resource = new UrlResource(filePath.toUri());if (resource.exists()) {return ResponseEntity.ok().header(HttpHeaders.CONTENT_TYPE, "application/x-mpegURL").body(resource);} else {return ResponseEntity.notFound().build();}} catch (MalformedURLException ex) {return ResponseEntity.badRequest().build();}}
}

vue代码

<template><div><video ref="videoPlayer" controls ></video></div>
</template>
import Hls from 'hls.js';
onMounted(() => {const video = videoPlayer.value;const videoSrc = 'http://localhost:9500/api/video/stream/5.m3u8'; // 替换为你的 .m3u8 视频流地址if (Hls.isSupported() && video) {const hls = new Hls();hls.loadSource(videoSrc);hls.attachMedia(video);hls.on(Hls.Events.MANIFEST_PARSED, () => {// video.play();});} else if (video && video.canPlayType('application/vnd.apple.mpegurl')) {// 如果浏览器原生支持 HLS（如 Safari）video.src = videoSrc;video.addEventListener('loadedmetadata', () => {video.play();});}
});
