Nesta página, mostramos como criar um projeto Google Cloud , ativar a API Live Stream, criar credenciais de autenticação e conceder à sua conta uma ou mais papéis do IAM. Esta página também mostra como criar um bucket do Cloud Storage para armazenar os arquivos de saída da transmissão ao vivo e como instalar um codificador para gerar streams de entrada que a API processa.
Criar um projeto
- 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.
-
Install the Google Cloud CLI.
-
Ao usar um provedor de identidade (IdP) externo, primeiro faça login na gcloud CLI com sua identidade federada.
-
Para inicializar a gcloud CLI, execute o seguinte comando:
gcloud init
-
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
(
roles/resourcemanager.projectCreator
), which contains theresourcemanager.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.
-
Verify that billing is enabled for your Google Cloud project.
-
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 theserviceusage.services.enable
permission. Learn how to grant roles.gcloud services enable livestream.googleapis.com
-
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.
-
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.

Create a Cloud Storage bucket:
Replacegcloud storage buckets create gs://BUCKET_NAME
BUCKET_NAME
with a bucket name that meets the bucket naming requirements.Instalar um codificador
Para usar a API, você precisa de um codificador para gerar streams de entrada que a API processe.
Instale o
ffmpeg
, já que esta página explica como usar offmpeg
para gerar streams de entrada. É possível instalar no Cloud Shell usando o seguinte comando.sudo apt install ffmpeg
Criar um bucket do Cloud Storage
Crie um bucket do Cloud Storage para armazenar o manifesto e os arquivos de segmento da transmissão ao vivo.
