        {
            // 获取视频文件流
            Stream videoStream = await Request.Content.ReadAsStreamAsync();

            // 保存视频文件到指定文件夹
            string videoPath = "视频文件保存路径";
            using (FileStream fileStream = new FileStream(videoPath, FileMode.Create))
            {
                await videoStream.CopyToAsync(fileStream);
            }

            // 连接摄像头
            FilterInfoCollection videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            VideoCaptureDevice videoSource = new VideoCaptureDevice(videoDevices[0].MonikerString);

            // 捕获视频帧并保存到指定文件夹
            string framePath = "视频帧保存路径";
            videoSource.NewFrame += (s, e) =>
            {
                Bitmap frame = (Bitmap)e.Frame.Clone();
                frame.Save(framePath);
            };
            videoSource.Start();

            // 返回上传结果
            return Ok("视频上传成功");
        }
    }
}
