The video has the same problem. https://storage.googleapis.com/video-transcode-az108/91a637d4-a5f2-41d8-bdcc-ba1af5de6a26

Hello, is the issue you are experiencing now fixed?

No, transcoding these two videos still fails.

The following is code

using Google.Api.Gax.ResourceNames;
using Google.Cloud.Video.Transcoder.V1;

public class GoogleCloudVideoTranscoder

    // 注意存储桶和 location 用同地区的，会更快

        while (true)
        {

            var currentJob = GetJob(job.JobName);
            Console.WriteLine($"{DateTime.Now}  {currentJob.State}");
            if (currentJob.State == Job.Types.ProcessingState.Succeeded

                Console.WriteLine(currentJob.Error);
                Console.WriteLine($"createTime ~ endTime :  {DateTime.Now - startTime }");
