在HarmonyOS开发中taskpool.SequenceRunner 拷贝传递 ArrayBuffer 出现异常？

Question

在HarmonyOS开发中taskpool.SequenceRunner 拷贝传递 ArrayBuffer 出现异常？利用 ImageReceiver 从摄像头获取帧 ArrayBuffer，然后将 ArrayBuffer 传入线程池做耗时算法分析。由于 ArrayBuffer 后续还需要使用，所以设置了 setCloneList 希望拷贝传递。代码如下：

private runner: taskpool.SequenceRunner = new taskpool.SequenceRunner(); 
 
let task = new taskpool.Task(run, buffer, width, height); 
task.setCloneList([buffer]); 
let result = await this.runner.execute(task);

发现报如下错误：10200006 An exception occurred during serialization, taskpool: failed to serialize arguments

Answer 1

import taskpool from '@ohos.taskpool'; 
 
@Concurrent 
function printArgs(args: number): number { 
  return args; 
} 
 
taskpool.execute(printArgs, 100).then((value: Object) => { // 100: test number 
});

如果注释掉@Concurrent，就会报10200006 An exception occurred during serialization, taskpool: failed to serialize arguments.
