Vor dem Start

Auf dieser Seite erfährst du, wie du ein Google Cloud-Projekt erstellst, die Live Stream API aktivierst, Authentifizierungsdaten erstellst und deinem Konto eine oder mehrere IAM-Rollen zuweist. Auf dieser Seite erfährst du auch, wie du einen Cloud Storage-Bucket zum Speichern der Ausgabedateien des Livestreams erstellst und wie du einen Encoder installierst, 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. To initialize the gcloud CLI, run the following command:

   gcloud init

4. Create or select a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   • 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.

5. Make sure that billing is enabled for your Google Cloud project.

6. Enable the Live Stream API:

   gcloud services enable livestream.googleapis.com

7. 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.

8. 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 PROJECT_ID with your project ID.

   • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:[e-mail].

   • Replace ROLE with each individual role.
9. Install the Google Cloud CLI.

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

    gcloud init

11. Create or select a Google Cloud project.

    Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

    • 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.

12. Make sure that billing is enabled for your Google Cloud project.

13. Enable the Live Stream API:

    gcloud services enable livestream.googleapis.com

14. 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.

15. 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 PROJECT_ID with your project ID.

    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:[e-mail].

    • Replace ROLE with each individual role.

Hinweis: Wenn Sie mehr Kontrolle über die Cloud Storage-Buckets Ihres Projekts haben möchten, fügen Sie Ihrem Google-Konto die IAM-Rolle roles/storage.admin hinzu.

Cloud Storage-Bucket erstellen

Erstelle einen Cloud Storage-Bucket für das Manifest und die Segmentdateien des Livestreams.

Google Cloud Console

1. In the Google Cloud console, go to the Cloud Storage Buckets page.

   Go to Buckets page

2. Click Create bucket.
3. On the Create a bucket page, enter your bucket information. To go to the next step, click Continue.
   • For Name your bucket, enter a name that meets the bucket naming requirements.
   • For Choose where to store your data, do the following:
     • Select a Location type option.
     • Select a Location option.
   • For Choose a default storage class for your data, select the following: Standard.
   • For Choose how to control access to objects, select an Access control option.
   • For Advanced settings (optional), specify an encryption method, a retention policy, or bucket labels.
4. Click Create.

Befehlszeile

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
