Hinweis

Auf dieser Seite erfahren Sie, wie Sie ein Google Cloud -Projekt erstellen, die Live Stream API aktivieren, Authentifizierungsanmeldedaten erstellen und Ihrem Konto eine oder mehrere IAM-Rollen zuweisen. Auf dieser Seite wird auch gezeigt, wie Sie einen Cloud Storage-Bucket zum Speichern der Ausgabedateien des Livestreams erstellen und wie Sie einen Encoder installieren, um Eingabestreams zu generieren, die von der API verarbeitet werden.

Projekt erstellen

  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. Wenn Sie einen externen Identitätsanbieter (IdP) verwenden, müssen Sie sich zuerst mit Ihrer föderierten Identität in der gcloud CLI anmelden.

  4. Führen Sie folgenden Befehl aus, um die gcloud CLI zu initialisieren: 

    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 (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. Wenn Sie einen externen Identitätsanbieter (IdP) verwenden, müssen Sie sich zuerst mit Ihrer föderierten Identität in der gcloud CLI anmelden.

  12. Führen Sie folgenden Befehl aus, um die gcloud CLI zu initialisieren:

    • 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.

    • USER_IDENTIFIER: the identifier for your user account—for example, myemail@example.com.
    • ROLE: the IAM role that you grant to your user account.
    18.

    Cloud Storage-Bucket erstellen

    Erstellen Sie einen Cloud Storage-Bucket zum Speichern der Manifest- und Segmentdateien des Livestreams.

  18. Create a Cloud Storage bucket: 
    gcloud storage buckets create gs://BUCKET_NAME
     Replace BUCKET_NAME with a bucket name that meets the bucket naming requirements.

    Encoder installieren

    Zur Verwendung der API benötigen Sie einen Encoder, um Eingabestreams zu generieren, die von der API verarbeitet werden.

    Installieren Sie ffmpeg, da auf dieser Seite beschrieben wird, wie Sie mit ffmpeg Eingabestreams generieren. Sie können es in Cloud Shell mit dem folgenden Befehl installieren.

    sudo apt install ffmpeg
