使用自定义预设的 azure 媒体服务转码

Question

我在 azure 网络服务中使用 webjob 来处理视频编码，默认预设没有修复 VVS（视频旋转问题）和 trim 视频选项。

当我使用自定义预设时，它将失败并且作业状态从 'scheduled' 变为 'processing' 然后变为 'Error' 而不是 'finished'。我只是想不通。它不会抛出异常也知道错误是什么

link 到我在 xml 中的预设。

//MediaService.cs
var localPath = Environment.GetEnvironmentVariable("WEBJOBS_PATH");
var filePath = Path.Combine(localPath, "CustomPreset.xml");
string configuration = File.ReadAllText(filePath); 

var multibitrateTask = job.Tasks.AddNew("Custom Encoding Task", azureMediaEncoder, configuration, TaskOptions.None);
multibitrateTask.InputAssets.Add(mediaServiceAsset);
multibitrateTask.OutputAssets.AddNew($"Multibirate ouput for {mediaServiceAsset.Name}", AssetCreationOptions.None);

job = await job.SubmitAsync(); 

//function.cs
if (jobMessage.EventType == "JobStateChange")
{
 //try get old and new state
 if (jobMessage.Properties.Any(p => p.Key == "OldState") && jobMessage.Properties.Any(p => p.Key == "NewState"))
  {
    string oldJobState = jobMessage.Properties.First(p => p.Key == "OldState").Value.ToString();
    string newJobState = jobMessage.Properties.First(p => p.Key == "NewState").Value.ToString();

await log.WriteLineAsync(string.Format("job state has changed from {0} to {1}", oldJobState, newJobState));

string newState = jobMessage.Properties["NewState"].ToString();
     if (newState == "Finished") //<--fails here
     {
       string jobId = jobMessage.Properties["JobId"].ToString();
      var mediaServiceWrapper = new MediaServiceWrapper(_mediaServiceName, _mediaServiceKey, _azureStorageAccount);
      var result = await mediaServiceWrapper.PrepareAssetsForAdaptiveStreamingAsync(jobId); 
    }
  }
}

所以我使用的是 Azure Media Encoder (AME)，现在我改为使用 Media Encoder Standard (MES)

IMediaProcessor 处理器 = GetLatestMediaProcessorByName("Media Encoder Standard");
