通过PotPlayer发现该MP4文件的编码格式为HEVC，而video标签不支持该编码格式的视频文件
在HTML文件中首先需要引用libe265.js来负责处理HEVC格式文件

而通过绝对路径来寻找本地视频文件则可通过后端（SpringBoot）编写接口进行操作
以下是Controller层代码
@RestController
@RequestMapping("/file")
@CrossOrigin(origins = "*")
public class FileController {
@Resource
public IFileService fileService;
/**
* 根据本地图片全路径，响应给浏览器1个图片流
*/
@GetMapping("/image/{fileName}")
public void showImage(HttpServletResponse response, @PathVariable("fileName") String fileName) {
fileService.show(response, fileName, "image");
}
/**
* 根据本地视频全路径，响应给浏览器1个视频
*/
@GetMapping ("/video")
public void showVideo(HttpServletResponse response, String fileName) {
fileService.show(response, fileName, "video");
}
}
以下是Sevice层代码
@Service
public class FileServiceImpl implements IFileService {
/**
* 响应文件
*
* @param response
* @param fileName 文件全路径
* @param type 响应流类型
*/
public void show(HttpServletResponse response, String fileName, String type) {
try {
FileInputStream fis = new FileInputStream(fileName); // 以byte流的方式打开文件
int i = fis.available(); //得到文件大小
byte data[] = new byte[i];
fis.read(data); //读数据
response.setContentType(type + "/*"); //设置返回的文件类型
OutputStream toClient = response.getOutputStream(); //得到向客户端输出二进制数据的对象
toClient.write(data); //输出数据
toClient.flush();
toClient.close();
fis.close();
} catch (ClientAbortException cae) {
cae.printStackTrace();
System.out.println("播放中断");
} catch (Exception e) {
e.printStackTrace();
System.out.println("文件不存在");
}
}
}
