如何获得 Mediaconvert 正在处理的特定工作的工作进展百分比？

如何解决如何获得 Mediaconvert 正在处理的特定工作的工作进展百分比？

我发现状态间隔更新事件在作业进行时每分钟发送到 Cloudwatch 事件，间隔也可以更改为 10 秒。如何在客户端显示 Cloudwatch 事件发送的百分比每 10 秒后发生一次事件？

解决方法

您需要从 CloudWatch 捕获 STATUS_UPDATE 事件，并将其提供给 Lambda 之类的服务，该服务可以更新数据库或您用来显示作业统计信息的任何数据源。

事件模式示例

{
  "source": [
    "aws.mediaconvert"
  ],"detail-type": [
    "MediaConvert Job State Change"
  ],"detail": {
    "status": [
      "STATUS_UPDATE"
    ]
  }
}

状态更新事件负载的示例：

{
    "version": "0","id": "ABC","detail-type": "MediaConvert Job State Change","source": "aws.mediaconvert","account": "111122223333 ","time": "2021-02-18T17:52:32Z","region": "us-west-2","resources": [
        "arn:aws:mediaconvert:us-west-2:111122223333 :jobs/1613670689802-emcngz"
    ],"detail": {
        "timestamp": 1613670752653,"accountId": "111122223333 ","queue": "arn:aws:mediaconvert:us-west-2:111122223333 :queues/Default","jobId": "1613670689802-emcngz","status": "STATUS_UPDATE","userMetadata": {},"framesDecoded": 2024,"jobProgress": {
            "phaseProgress": {
                "PROBING": {
                    "status": "COMPLETE","percentComplete": 100
                },"TRANSCODING": {
                    "status": "PROGRESSING","percentComplete": 2
                },"UPLOADING": {
                    "status": "PENDING","percentComplete": 0
                }
            },"jobPercentComplete": 7,"currentPhase": "TRANSCODING","retryCount": 0
        }
    }
}

MediaConvert 提供作业所处每个阶段（探测输入、转码和上传输出）的精细百分比以及总体百分比。 MediaConvert 控制台 UI 上显示的那个是 jobPercentComplete，可能就是您想要捕获的那个。
