准备工作

本页介绍了如何创建 Google Cloud 项目、启用 Transcoder API、创建身份验证凭据,以及向您的账号授予一个或多个 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.

    • 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:myemail@example.com.

    • 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.

    • 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:myemail@example.com.

    • Replace ROLE with each individual role.

创建 Cloud Storage 存储桶

如需保存转码作业输出文件,请在 Transcoder API 作业所在的位置创建一个 Cloud Storage 存储桶。如需了解详情,请参阅“位置”页面的媒体资源部分。

  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。
