We want to transcode videos into HLS format with segment duration of 1 second. We have the desired transcoder output being generated using FFMPEG currently, we have replicated the config for this into the GCP transcoder config format, but we are only recieving "Internal Server Error" (code: 13) for all jobs.

All jobs are being created with the TranscoderServiceClient library, using JS and node 18. https://cloud.google.com/nodejs/docs/reference/video-transcoder/latest/video-transcoder/v1.transcoderserviceclient

Problem you have encountered:

"Internal Server Error" is returned from API when requesting with Segment Duration equal to 1 second (and GOP duration set to 0.5s or 1s).

{
  labels: {},
  name: 'projects/.../locations/us-central1/jobs/6a437701-f6b3-4761-9bb3-4f31142360ca',
  inputUri: '',
  outputUri: '',
  state: 'FAILED',
  createTime: { seconds: '1686188771', nanos: 73025928 },
  startTime: { seconds: '1686188776', nanos: 948000000 },
  endTime: { seconds: '1686188999', nanos: 13928961 },
  ttlAfterCompletionDays: 30,
  error: { details: [], code: 13, message: 'Internal error occurred.' },
  mode: 'PROCESSING_MODE_UNSPECIFIED',
  config: {
    ...
  },
  jobConfig: 'config'
}

What you expected to happen:

A HLS stream to be produced with a Segment Duration to be 1s (or atleast a better error than "Internal server error" to allow us to track down what the issue is with our config)

Steps to reproduce:

A job config (JS - IJobConfig) that fails:

config: {
elementaryStreams: [
    {
      key: "SD",
      videoStream: {
        h264: {
          heightPixels: 360,
          widthPixels: 640,
          bitrateBps: 550000,
          frameRate: 30,
          gopDuration: {
            nanos: 500000000
          }
        },
      },
    },
    {
      key: "HD",
      videoStream: {
        h264: {
          heightPixels: 720,
          widthPixels: 1280,
          bitrateBps: 2500000,
          frameRate: 30,
          gopDuration: {
            nanos: 500000000
          }
        },
      },
    },
    {
      key: "audio-stream0",
      audioStream: {
        codec: "aac",
        bitrateBps: 64000,
      },
    },
  ],
  muxStreams: [
    {
      key: "sd",
      container: "ts",
      elementaryStreams: ["SD", "audio-stream0"],
      segmentSettings: {
        segmentDuration: {
          seconds: 1
        },
        individualSegments: false
      },
    },
    {
      key: "hd",
      container: "ts",
      elementaryStreams: ["HD", "audio-stream0"],
      segmentSettings: {
        segmentDuration: {
          seconds: 1
        },
        individualSegments: false
      },
    },
  ],
  manifests: [
    {
      fileName: "master.m3u8",
      type: "HLS",
      muxStreams: ["sd", "hd"],
    },
  ],
},

We have encountered this error when using the H265 codec also.

Other information (workarounds you have tried, documentation consulted, etc):

We have be able to transcode the videos with other transcoder configs, with larger Segment Durations.

Maybe there is something else wrong in our config that you can help us spot.
