本页面介绍了如何使用 Video Stitcher API 和 curl、PowerShell 或客户端库将广告插播到直播中。

准备工作

在调用 Video Stitcher API 之前，请完成以下步骤：

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。

安装 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

创建或选择 Google Cloud 项目。

选择或创建项目所需的角色

选择项目：选择项目不需要特定的 IAM 角色，您可以选择已获授角色的任何项目。
创建项目：如需创建项目，您需要拥有 Project Creator 角色 (roles/resourcemanager.projectCreator)，该角色包含 resourcemanager.projects.create 权限。了解如何授予角色。

创建 Google Cloud 项目：
```
gcloud projects create PROJECT_ID
```
将 PROJECT_ID 替换为您要创建的 Google Cloud 项目的名称。
选择您创建的 Google Cloud 项目：
```
gcloud config set project PROJECT_ID
```
将 PROJECT_ID 替换为您的 Google Cloud 项目名称。

验证是否已为您的 Google Cloud 项目启用结算功能。

启用 Video Stitcher API：

启用 API 所需的角色

如需启用 API，您需要拥有 Service Usage Admin IAM 角色 (roles/serviceusage.serviceUsageAdmin)，该角色包含 serviceusage.services.enable 权限。了解如何授予角色。

gcloud services enable videostitcher.googleapis.com

如果您使用的是本地 shell，请为您的用户账号创建本地身份验证凭证：

gcloud auth application-default login

如果您使用的是 Cloud Shell，则无需执行此操作。

如果系统返回身份验证错误，并且您使用的是外部身份提供方 (IdP)，请确认您已使用联合身份登录 gcloud CLI。

向您的用户账号授予角色。对以下每个 IAM 角色运行以下命令一次： roles/videostitcher.admin

gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

替换以下内容：

PROJECT_ID：您的项目 ID。
USER_IDENTIFIER：您的用户账号的标识符。例如，myemail@example.com。
ROLE：您授予用户账号的 IAM 角色。

本快速入门需要 MPEG-DASH 或 HTTP Live Streaming (HLS) 清单文件。您可以按照Live Stream API 快速入门中的说明创建一个直播，直到播放生成的直播部分。
您也可以选择在此快速入门中使用内容分发网络 (CDN)。如果您尚未配置 CDN，请按照媒体 CDN 快速入门中的步骤操作，并进行以下修改：
1. 将 MPEG-DASH 或 HLS 清单文件和媒体片段上传到 Cloud Storage 存储桶。
2. 您不必将 Cloud Storage 存储桶设为可公开读取。
3. 您可以使用签名网址或未签名网址。

创建 CDN 密钥

Video Stitcher API 可以从内容分发网络 (CDN) 中提取视频。如果视频素材资源受网址签名保护，则必须向 Video Stitcher API 注册 CDN 密钥。

如需注册 CDN 密钥，请使用 projects.locations.cdnKeys.create 方法。

REST（媒体 CDN）

在使用任何请求数据之前，请先进行以下替换：

PROJECT_NUMBER：您的 Google Cloud 项目编号；该编号位于 IAM 设置页面上的项目编号字段中
LOCATION：用于创建 CDN 密钥的位置；请使用某个受支持的区域
显示位置
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
CDN_KEY_ID：CDN 密钥的用户定义标识符，将成为 CDN 密钥资源名称的最后一个组成部分。此 ID 只能包含小写字母、数字和连字符。第一个字符必须是字母，最后一个字符必须是字母或数字，并且整个 ID 的长度不得超过 63 个字符。
HOSTNAME：要与此 CDN 密钥关联的 CDN 的主机名（例如，IP 地址 [如 35.190.60.252] 或域名 [如 cdn.example.com]）
MEDIA_CDN_KEYNAME：媒体 CDN 密钥的密钥集名称
MEDIA_CDN_PRIVATE_KEY：以 base64 编码的字符串形式表示的 64 字节 Ed25519 私钥。如需了解详情，请参阅为媒体 CDN 创建私钥。

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI，或者使用了 Cloud Shell，这会使您自动登录 gcloud CLI。您可以通过运行 gcloud auth list 来检查当前的活跃账号。

检查结果

如需检查 CDN 密钥是否已创建，请使用 projects.locations.operations.get 方法。如果响应包含 "done: false"，请重复执行该命令，直到响应包含 "done: true"。

在使用任何请求数据之前，请先进行以下替换：

PROJECT_NUMBER：您的 Google Cloud 项目编号；该编号位于 IAM 设置页面上的项目编号字段中
LOCATION：数据的位置；请使用某个受支持的地区
显示位置
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
OPERATION_ID：操作的标识符

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI，或者使用了 Cloud Shell，这会使您自动登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID"

PowerShell (Windows)

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.common.OperationMetadata",
    "createTime": CREATE_TIME,
    "endTime": END_TIME,
    "target": "projects/PROJECT_NUMBER/locations/LOCATION/cdnKeys/CDN_KEY_ID",
    "verb": "create",
    "cancelRequested": false,
    "apiVersion": "v1"

    "name": "projects/PROJECT_NUMBER/locations/LOCATION/cdnKeys/CDN_KEY_ID",
    "hostname": "HOSTNAME",
    "mediaCdnKey": {
      "keyName": "MEDIA_CDN_KEYNAME"
    }
  }
}

创建补位广告

当无法插入广告时，Video Stitcher API 会插入默认的补位视频。您必须向 Video Stitcher API 注册补位视频，以指明在没有广告时将使用的补位内容。补位内容视频可以是任何包含至少一个音轨的 MP4 文件。

如需创建补位内容，请使用 projects.locations.slates.create 方法。

REST

在使用任何请求数据之前，请先进行以下替换：

PROJECT_NUMBER：您的 Google Cloud 项目编号；该编号位于 IAM 设置页面上的项目编号字段中
LOCATION：要创建补位内容的位置；请使用某个受支持的区域
显示位置
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
SLATE_ID：用户定义的平板标识符。此 ID 只能包含小写字母、数字和连字符。第一个字符必须是字母，最后一个字符必须是字母或数字，并且整个 ID 的长度不得超过 63 个字符。
SLATE_URL：MP4 视频的公开 URI，该视频至少包含一个音轨（示例视频）

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

将请求正文保存在名为 request.json 的文件中。在终端中运行以下命令，在当前目录中创建或覆盖此文件：

cat > request.json << 'EOF'
{
  "uri": "SLATE_URL"
}
EOF

然后，执行以下命令以发送 REST 请求：

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/slates?slateId=SLATE_ID"

PowerShell (Windows)

将请求正文保存在名为 request.json 的文件中。在终端中运行以下命令，在当前目录中创建或覆盖此文件：

@'
{
  "uri": "SLATE_URL"
}
'@  | Out-File -FilePath request.json -Encoding utf8

然后，执行以下命令以发送 REST 请求：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/slates?slateId=SLATE_ID" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

  "adTagUri": "AD_TAG_URI",
  "defaultSlate": "projects/PROJECT_NUMBER/locations/LOCATION/slates/SLATE_ID",
  "adTracking": "SERVER",
  "stitchingPolicy": "CUT_CURRENT"
}
EOF

然后，执行以下命令以发送 REST 请求：

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/liveConfigs?liveConfigId=LIVE_CONFIG_ID"

收到响应后，您可以通过引用响应对象的 playUri 字段中的 URI 来播放拼接了广告的直播。

Video Stitcher API 会为每个请求生成唯一的会话 ID。如果在过去 5 分钟内未请求 playUri，会话将过期。

播放拼接了广告的直播

使用响应对象的 playUri 字段中的 URI 播放拼接了广告的直播。如需在 Shaka Player 中播放此直播，请完成以下步骤：

前往在线媒体播放器 Shaka Player。
点击顶部导航栏中的自定义内容。
点击 + 按钮。
将 playUri 字段的值 (PLAY_URI) 粘贴到清单网址框中。
在名称框中输入一个名称。
点击保存。
点击播放。

插入广告插播时间点

Video Stitcher API 会针对每个广告插播时间点插入从广告代码中检索到的广告。广告插播时间点在清单中使用广告标记表示。广告标记由直播编码器插入。如需详细了解支持的 HLS 和 DASH 广告标记，请参阅广告标记文档。

如果您使用 Live Stream API 创建直播，则可以使用频道活动插入广告插播时间。

确认广告已拼接

广告必须先经过编码，然后才能拼接进直播会话。如果您看到的是补位内容视频而不是广告，请等待广告编码，然后插入另一个广告插播时间点。
