          string secretKey = "SECRET_KEY"; // TencentCloud API `SecretKey`. For more information on how to get it, visit https://console.tencentcloud.com/cam/capi.
          long durationSecond = 600;          // Validity period of the request signature in seconds
          QCloudCredentialProvider qCloudCredentialProvider = new DefaultQCloudCredentialProvider(secretId, 
            secretKey, durationSecond);
          
          this.cosXml = new CosXmlServer(config, qCloudCredentialProvider);
        }
         /// Capture video frames
        public void GetSnapshot()
        {
          // Bucket name in the format of `BucketName-APPID`. You can get the `APPID` by referring to https://console.tencentcloud.com/developer.
          string bucket = "examplebucket-1250000000";
          string key = "video.mp4"; // Object key of the media file, which should be replaced with the actual object key of the media file existing in the bucket
          float time = 1.5F; // Screenshot time point expressed as a floating point number
          string destPath = @"temp-source-file"; // The path to save the screenshot file, which needs to be replaced with a local specific path, such as "/usr/local/"
          GetSnapshotRequest request = new GetSnapshotRequest(bucket, key, time, destPath);
          // Execute the request
