    Before you begin

    This page shows how to create a Google Cloud project, enable the Live Stream API, create authentication credentials , and grant your account one or more IAM roles . This page also shows how to create a Cloud Storage bucket to hold the live stream output files and how to install an encoder to generate input streams that the API processes.

    Create a project

    1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

    2. Install the Google Cloud CLI.

    3. If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity .

    4. To initialize the gcloud CLI, run the following command:

      gcloud  
init

    5. Create or select a Google Cloud project .

      Roles required to select or create a project

      • Select a project : Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
      • Create a project : To create a project, you need the Project Creator role ( roles/resourcemanager.projectCreator ), which contains the resourcemanager.projects.create permission. Learn how to grant roles .

      • 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.

    6. Verify that billing is enabled for your Google Cloud project .

    7. Enable the Live Stream API:

      Roles required to enable APIs

      To enable APIs, you need the Service Usage Admin IAM role ( roles/serviceusage.serviceUsageAdmin ), which contains the serviceusage.services.enable permission. Learn how to grant roles .

       
      gcloud  
services  
 enable 
  
livestream.googleapis.com

    8. If you're using a local shell, then create local authentication credentials for your user account:

      gcloud  
auth  
application-default  
login

      You don't need to do this if you're using Cloud Shell.

      If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity .

    9. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/livestream.editor 

      gcloud  
projects  
add-iam-policy-binding  
 PROJECT_ID 
  
--member = 
 "user: USER_IDENTIFIER 
" 
  
--role = 
 ROLE

      Replace the following:

      • PROJECT_ID : Your project ID.
      • USER_IDENTIFIER : The identifier for your user account. For example, myemail@example.com .
      • ROLE : The IAM role that you grant to your user account.

    10. Install the Google Cloud CLI.

    11. If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity .

    12. To initialize the gcloud CLI, run the following command:

      gcloud  
init

    13. Create or select a Google Cloud project .

      Roles required to select or create a project

      • Select a project : Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
      • Create a project : To create a project, you need the Project Creator role ( roles/resourcemanager.projectCreator ), which contains the resourcemanager.projects.create permission. Learn how to grant roles .

      • 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.

    14. Verify that billing is enabled for your Google Cloud project .

    15. Enable the Live Stream API:

      Roles required to enable APIs

      To enable APIs, you need the Service Usage Admin IAM role ( roles/serviceusage.serviceUsageAdmin ), which contains the serviceusage.services.enable permission. Learn how to grant roles .

       
      gcloud

livestream.googleapis.com

    16. If you're using a local shell, then create local authentication credentials for your user account:

      gcloud  
auth  
application-default  
login

      You don't need to do this if you're using Cloud Shell.

      If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity .

    17. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/livestream.editor 

      gcloud  
projects

" 
  
--role = 
 ROLE

      Replace the following:

      • PROJECT_ID : Your project ID.

    Install an encoder

    To use the API, you need an encoder to generate input streams that the API processes.

    Install ffmpeg as this page covers how to use ffmpeg to generate input streams. You can install this in Cloud Shell using the following command.

     sudo apt install ffmpeg
