Create and manage input endpoints

This page shows you how to create and manage Live Stream API input endpoints. You send input video streams to these endpoints.

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 input endpoint

To create an input endpoint, use the projects.locations.inputs.create 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 in which to create the input endpoint; 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
• INPUT_ID: a user-defined identifier for the new input endpoint to create (to which you send your input stream). This value must be 1-63 characters, begin and end with [a-z0-9], and can contain dashes (-) between characters. For example, my-input.

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'
{
  "type": "RTMP_PUSH"
}
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/inputs?inputId=INPUT_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:

@'
{
  "type": "RTMP_PUSH"
}
'@  | 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/inputs?inputId=INPUT_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/inputs/INPUT_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.

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:

@'
{
  "preprocessingConfig": {
    "crop": {
      "topPixels": 10,
      "bottomPixels": 10,
      "leftPixels": 5,
      "rightPixels": 5
    }
  }
}
'@  | 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 PATCH `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/inputs/INPUT_ID?updateMask=preprocessingConfig" | 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/inputs/INPUT_ID",
    "verb": "update",
    "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 input endpoints

To list all of the input endpoints you created in a location, use the projects.locations.inputs.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 where your input endpoint is located; 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/inputs"

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/inputs" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "inputs": [
    {
      "name": "projects/PROJECT_NUMBER/locations/LOCATION/inputs/my-input",
      "createTime": CREATE_TIME,

require "google/cloud/video/live_stream"

##
# List the input endpoints
#
# @param project_id [String] Your Google Cloud project (e.g. "my-project")
# @param location [String] The location (e.g. "us-central1")
#
def list_inputs project_id:, location:
  # Create a Live Stream client.
  client = Google::Cloud::Video::LiveStream.livestream_service

  # Build the resource name of the parent.
  parent = client.location_path project: project_id, location: location

  # Get the list of inputs.
  response = client.list_inputs parent: parent

  puts "Inputs:"
  # Print out all inputs.
  response.each do |input|
    puts input.name
  end
end

Delete an input endpoint

To delete an input endpoint, use the projects.locations.inputs.delete 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 where your input endpoint is located; 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
• INPUT_ID: the user-defined identifier for the input endpoint

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 DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/inputs/INPUT_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.

Execute the following command:

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

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -Uri "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/inputs/INPUT_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/inputs/INPUT_ID",
    "verb": "delete",
    "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.
