开始前的准备工作

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。本页面还介绍了如何设置 Cloud Storage 存储桶以保存转码器作业输出文件。

创建项目

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.
如果您使用的是外部身份提供方 (IdP)，则必须先 使用联合身份登录 gcloud CLI。
如需初始化 gcloud CLI，请运行以下命令：
gcloud init
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.
Verify that billing is enabled for your Google Cloud project.
Enable the Transcoder API:
gcloud services enable transcoder.googleapis.com
Create local authentication credentials for your user account:
gcloud auth application-default login
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/transcoder.admin
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, [e-mail].
• ROLE: the IAM role that you grant to your user account.

• PROJECT_ID: your project ID.
• USER_IDENTIFIER: the identifier for your user account—for example, [e-mail].
• ROLE: the IAM role that you grant to your user account.
注意： 向您的 Google 账号添加 IAM 角色 roles/storage.admin，以便更好地控制项目的 Cloud Storage 存储分区。

创建 Cloud Storage 存储桶

如需保存转码器作业输出文件，请在与 Transcoder API 作业相同的位置创建 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. Create a Cloud Storage bucket and configure it as follows:
   • Set the storage class to S（标准）。
   • 将存储位置设置为以下项： US（美国）。
   • 将 BUCKET_NAME 替换为 唯一的存储桶名称。请勿在存储桶名称中添加敏感信息，因为存储桶命名空间是全局性的，公开可见。

   gcloud storage buckets create gs://BUCKET_NAME --default-storage-class STANDARD --location US

   • 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。
