Create and manage assets

This page shows you how to create and manage Live Stream API assets. Assets are video or images that can be used with the Live Stream API. You can use an asset to insert a slate into a live stream.

Supported media formats

The Live Stream API supports the following media codecs and formats for assets.

Input media	Supported formats
Video file formats	MP4, MPEG-TS, FLV
Video codecs	H.264
Audio codecs	AAC, AC3, MP2, MP3
Image file formats	JPG
Maximum size	250 MB
Maximum resolutions	1920x1080

Set up your Google Cloud project and authentication

If you have not created a Google Cloud project and credentials, see Before you begin.

Create an asset

To create an asset, use the projects.locations.assets.create method. The following sample creates a video asset.

REST

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

• PROJECT_NUMBER: your Google Cloud project number; this is located in the Project number field on the IAM Settings page
• LOCATION: the location in which to create the asset; use one of the supported regions
  Show locations
  • us-central1
  • us-east1
  • us-east4
  • us-west1
  • us-west2
  • northamerica-northeast1
  • southamerica-east1
  • asia-east1
  • asia-east2
  • asia-northeast1
  • asia-southeast1
  • australia-southeast1
  • europe-west1
  • europe-west2
  • europe-west3
  • europe-west4
• ASSET_ID: A user-defined identifier for the new asset to create. This value must be 1-63 characters, begin and end with [a-z0-9], and can contain dashes (-) between characters. For example, my-asset.
• ASSET_URI: the URI of the video in your Cloud Storage bucket to use, such as gs://my-bucket/my-video.mp4 (see the supported media formats)

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json. Run the following command in the terminal to create or overwrite this file in the current directory:

cat > request.json << 'EOF'
{
  "video": {
    "uri": "ASSET_URI"
  }
}
EOF

Then execute the following command to send your REST request:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/assets?assetId=ASSET_ID"

PowerShell (Windows)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json. Run the following command in the terminal to create or overwrite this file in the current directory:

@'
{
  "video": {
    "uri": "ASSET_URI"
  }
}
'@  | Out-File -FilePath request.json -Encoding utf8

Then execute the following command to send your REST request:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/assets?assetId=ASSET_ID" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.video.livestream.v1.OperationMetadata",
    "createTime": CREATE_TIME,
    "target": "projects/PROJECT_NUMBER/locations/LOCATION/assets/ASSET_ID",
    "verb": "create",
    "requestedCancellation": false,
    "apiVersion": "v1"
  },
  "done": false
}

This command creates a long-running operation (LRO) that you can use to track the progress of your request. See Manage long-running operations for more information.

List assets

To list all of the assets you created in a location, use the projects.locations.assets.list method.

REST

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

• PROJECT_NUMBER: your Google Cloud project number; this is located in the Project number field on the IAM Settings page
• LOCATION: the location of your assets; use one of the supported regions
  Show locations
  • us-central1
  • us-east1
  • us-east4
  • us-west1
  • us-west2
  • northamerica-northeast1
  • southamerica-east1
  • asia-east1
  • asia-east2
  • asia-northeast1
  • asia-southeast1
  • australia-southeast1
  • europe-west1
  • europe-west2
  • europe-west3
  • europe-west4

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Execute the following command:

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/assets"

PowerShell (Windows)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.

Execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/assets" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "assets": [
    {
      "name": "projects/PROJECT_NUMBER/locations/LOCATION/assets/ASSET_ID",
      "createTime": CREATE_TIME,
