准备工作

此页面介绍了如何创建 Google Cloud 项目、启用 Transcoder API、create 身份验证凭据，然后授予 你的账号一个或多个 IAM 角色。本页面还介绍了 设置一个 Cloud Storage 存储桶，以保存转码器作业输出文件。

创建项目

1. 登录您的 Google Cloud 账号。如果您是 Google Cloud 新手，请创建一个账号来评估我们的产品在实际场景中的表现。新客户还可获享 $300 赠金，用于运行、测试和部署工作负载。
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. 确保您的 Google Cloud 项目已启用结算功能。

6. Enable the Transcoder API:

   gcloud services enable transcoder.googleapis.com

7. Create local authentication credentials for your user account:

   gcloud auth application-default login

8. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/transcoder.admin

   gcloud projects add-iam-policy-binding PROJECT_ID --member="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. 确保您的 Google Cloud 项目已启用结算功能。

13. Enable the Transcoder API:

    gcloud services enable transcoder.googleapis.com

14. Create local authentication credentials for your user account:

    gcloud auth application-default login

15. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/transcoder.admin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="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.

注意 ：如需了解详情，请将 IAM 角色 roles/storage.admin 添加到您的 Google 账号 控制项目的 Cloud Storage 存储分区。

创建 Cloud Storage 存储桶

要保存转码器作业输出文件，请在以下位置创建一个 Cloud Storage 存储桶： 与 Transcoder API 作业位于同一个位置。有关详情，请参阅 “地理位置”的媒体资源部分 页面。

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 unique bucket name. Don't include sensitive information in the bucket name, because the bucket namespace is global and publicly visible.
   • 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.
5. 点击创建文件夹并输入名称，以创建一个用于保存已编码的视频输出的文件夹。
