经由过程PotPlayer发明该MP4文件的编码格局为HEVC，而video标签没有撑持该编码格局的视频文件
正在HTML文件外起首须要援用libe两65.js来负责处置惩罚HEVC格局文件

下列是Controller层代码
@RestController
@RequestMapping("/file")
@CrossOrigin(origins = "*")
public class FileController {
@Resource
public IFileService fileService;
/**
* 按照当地图片齐路径，相应给涉猎器1个图片流
*/
@GetMapping("/image/{fileName}")
public void showImage(HttpServletResponse response, @PathVariable("fileName") String fileName) {
fileService.show(response, fileName, "image");
}
/**
* 按照当地视频齐路径，呼应给涉猎器1个视频
*/
@GetMapping ("/video")
public void showVideo(HttpServletResponse response, String fileName) {
fileService.show(response, fileName, "video");
}
}下列是Sevice层代码
@Service
public class FileServiceImpl implements IFileService {
/**
* 呼应文件
*
* @param response
* @param fileName 文件齐路径
* @param type 呼应流范例
*/
public void show(HttpServletResponse response, String fileName, String type) {
try {
FileInputStream fis = new FileInputStream(fileName); // 以byte流的体式格局翻开文件
int i = fis.available(); //获得文件巨细
byte data[] = new byte[i];
fis.read(data); //读数据
response.setContentType(type + "/*"); //配置返归的文件范例
OutputStream toClient = response.getOutputStream(); //获得向客户端输入两入造数据的东西
toClient.write(data); //输入数据
toClient.flush();
toClient.close();
fis.close();
} catch (ClientAbortException cae) {
cae.printStackTrace();
System.out.println("播搁中止");
} catch (Exception e) {
e.printStackTrace();
System.out.println("文件没有具有");
}
}
}到此那篇闭于HTML5兼容HEVC视频格局且撑持当地相对路径造访的文章便引见到那了,更多相闭HTML5兼容HEVC视频格局形式请搜刮剧本之野之前的文章或者连续涉猎上面的相闭文章，心愿巨匠之后多多撑持剧本之野！
