    • Replace ROLE with each individual role.
  9. Install the Google Cloud CLI.
  10. To initialize the gcloud CLI, run the following command:

    gcloud init
  11. Create or select a Google Cloud project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  12. Make sure that billing is enabled for your Google Cloud project.

  13. Enable the Transcoder API:

    gcloud services enable transcoder.googleapis.com
  14. Create local authentication credentials for your user account:

    gcloud auth application-default login
  15. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/transcoder.admin, roles/storage.admin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="USER_IDENTIFIER" --role=ROLE
    • Replace PROJECT_ID with your project ID.
    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.

    • Replace ROLE with each individual role.

Create a Cloud Storage bucket

  1. In the Google Cloud console, go to the Cloud Storage Buckets page.

    Go to Buckets page

  2. Click Create bucket.
  3. On the Create a bucket page, enter your bucket information. To go to the next step, click Continue.
    • For Name your bucket, enter a unique bucket name. Don't include sensitive information in the bucket name, because the bucket namespace is global and publicly visible.
    • For Choose where to store your data, do the following:
      • Select a Location type option.
      • Select a Location option.
    • For Choose a default storage class for your data, select the following: Standard.
    • For Choose how to control access to objects, select an Access control option.
    • For Advanced settings (optional), specify an encryption method, a retention policy, or bucket labels.
  4. Click Create.
  5. Click Create Folder and enter a name to create a folder in which to save the encoded video outputs.

Transcode a video using the Transcoder API

You need a video at least 5 seconds in duration from your local machine for the following steps (sample video). See the list of supported input and output formats.

Upload a video to your Cloud Storage bucket

  1. In the Google Cloud console, go to the Cloud Storage Browser page.
    Go to the Cloud Storage Browser page
  2. Click the name of your bucket to open it.
  3. Click Upload files.
  4. Select a video file to upload from your local machine.

Your video is now saved to the Cloud Storage bucket.

Create a transcoding job

By default, the Transcoder API transcodes video using H.264 encoding and MP4, HLS, and MPEG-DASH packaging. For each input video, it delivers output renditions in high definition (1280x720 pixels) and standard definition (640x360 pixels).

To create a job, use the projects.locations.jobs.create method. The following code samples create a basic transcoding job using a preset.

REST

Before using any of the request data, make the following replacements:

  • PROJECT_ID: Your Google Cloud project ID listed in the IAM Settings.
  • LOCATION: The location where your job will run. Use one of the supported regions.
    Show locations
    • us-central1
    • us-west1
    • us-west2
    • us-east1
    • us-east4
    • southamerica-east1
    • northamerica-northeast1
    • asia-east1
    • asia-northeast1
    • asia-northeast3
    • asia-south1
    • asia-southeast1
    • australia-southeast1
    • europe-west1
    • europe-west2
    • europe-west4
  • STORAGE_BUCKET_NAME: The name of the Cloud Storage bucket you created.
  • STORAGE_INPUT_VIDEO: The name of the video in your Cloud Storage bucket that you are transcoding, such as my-vid.mp4. This field should take into account any folders that you created in the bucket (for example, input/my-vid.mp4).
  • STORAGE_OUTPUT_FOLDER: The Cloud Storage folder name where you want to save the encoded video outputs.

To send your request, expand one of these options:

This particular REST example uses the optional fields query parameter to only show the created resource name in the response.

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/jobs/JOB_ID"
}

gcloud

  1. Make the following replacements for the gcloud command:
    • STORAGE_BUCKET_NAME: The name of the Cloud Storage bucket you created.
    • STORAGE_INPUT_VIDEO: The name of the video in your Cloud Storage bucket that you are transcoding, such as my-vid.mp4. This field should take into account any folders that you created in the bucket (for example, input/my-vid.mp4).
    • LOCATION: The location where your job will run. Use one of the supported regions.
      Show locations
      • us-central1
      • us-west1
      • us-west2
      • us-east1
      • us-east4

      • asia-northeast3
      • asia-south1
      • asia-southeast1
      • australia-southeast1
      • europe-west1
      • europe-west2
      • europe-west4
    • STORAGE_OUTPUT_FOLDER: The Cloud Storage folder name where you want to save the encoded video outputs.
  2. Run the following command:
    gcloud transcoder jobs create \
      --input-uri="gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO" \
      --location=LOCATION \
      --output-uri="gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/"
    
    You should see a response similar to the following:
    {
      "config": {
       ...
      },
      "createTime": CREATE_TIME,
      "name": "projects/PROJECT_NUMBER/locations/LOCATION/jobs/JOB_ID",
      "state": "PENDING",
      "ttlAfterCompletionDays": 30
    }

    # Build the resource name of the job.
    name = client.job_path project: project_id, location: location, job: job_id
    
    # Get the job.
    job = client.get_job name: name
    
    # Print the job state.
    puts "Job state: #{job.state}"

    If the state is SUCCEEDED, the job is complete and your video outputs are now available in your Cloud Storage bucket's list of encoded files.

    Play your video

    To play the generated media file in Shaka Player, complete the following steps:

    1. Make the Cloud Storage bucket you created publicly readable.
    2. To enable cross-origin resource sharing (CORS) on a Cloud Storage bucket, do the following:
      1. Create a JSON file that contains the following:
        [
          {
            "origin": ["https://shaka-player-demo.appspot.com/"],
            "responseHeader": ["Content-Type", "Range"],
            "method": ["GET", "HEAD"],
            "maxAgeSeconds": 3600
          }
        ]
      2. Run the following command after replacing JSON_FILE_NAME with the name of the JSON file you created in the previous step:
        gcloud storage buckets update gs://STORAGE_BUCKET_NAME --cors-file=JSON_FILE_NAME.json
    3. Pick one of the MP4 or manifest files generated by the transcoding job in the Cloud Storage bucket. Click Copy URL in the file's Public access column.
    4. Navigate to Shaka Player, an online live stream player.
    5. Click Custom Content in the top navigation bar.
    6. Click the + button.
    7. Paste the public URL of the file into the Manifest URL box.

      Enter the URL of the file in Shaka Player.

    8. Type a name in the Name box.

    9. Click Save.

    10. Click Play.
