你是什么语言的啊？给您个java触发持久化的转码demo
package demo;
import com.qiniu.common.QiniuException;
import com.qiniu.processing.OperationManager;
import com.qiniu.util.Auth;
import com.qiniu.util.StringMap;
import com.qiniu.util.UrlSafeBase64;

public class WaterMarkDemo {

public static void main(String[] args) throws QiniuException {

String ACCESS_KEY = "ACCESS_KEY";
String SECRET_KEY = "SECRET_KEY";
Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);
OperationManager operater = new OperationManager(auth);

StringMap params = new StringMap().putWhen("force", 1, true).putNotEmpty("pipeline", "pipeline");

//image / 后面的水印源图片网址（经过 URL 安全的 Base64 编码），必须有效且返回一张图片
String fops ="avthumb/mp4";
fops += "|saveas/" + UrlSafeBase64.encodeToString("dbucket"+":"+"dkey");

String id = operater.pfop("sbucket", "skey", fops, params);
System.out.println(id);
}

}
