如需为您的项目启用 Video Stitcher API，请联系您的客户代表或销售团队了解详情。

创建和管理实时配置

本文档介绍了如何管理实时配置。实时配置用于配置实时会话。如需了解详情，请参阅 REST 文档。

准备工作

如需创建直播会话，您必须先配置直播编码器，以便为 Video Stitcher API 生成源 HLS 或 DASH 清单。这些清单在广告插播时间点边界处包含特定的广告标记用于广告拼接目的。您可以按照某个 Live Stream API 快速入门创建具有兼容清单的直播。

如需详细了解受支持的 HLS 和 DASH 广告标记，请参阅广告标记文档。

定义实时配置

定义实时配置时，必须填写以下字段：

sourceUri
adTagUri
defaultSlate
adTracking

sourceUri 指定来源直播的 HLS 或 DASH 的网址清单来插入广告。如果提供的网址引用 HLS 清单，Video Stitcher API 会返回 HLS 播放网址；如果提供的网址引用 DASH 清单，则会返回 DASH 播放网址。

adTagUri 指定返回广告元数据的广告服务器的网址。

defaultSlate 用于指定没有可选广告时使用的默认可选广告在广告插播时间点的广告标记 SCTE-35 消息中指定。如需详细了解管理可选广告，请参阅可选广告文档。

adTracking 用于确定客户端播放器是否应该触发播放，或视频拼接 API 会在代表客户端玩家。有关客户端广告跟踪的更多信息请参阅处理客户端广告跟踪。

实时配置包含用于预加载广告和定义自定义标头的可选字段。

注册实时配置

如需注册实时配置，请使用 projects.locations.liveConfigs.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；此值位于 IAM 设置页面上的项目编号字段中
LOCATION：要在其中创建实时配置的位置；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
LIVE_CONFIG_ID：实时配置的用户定义标识符。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，整个 ID 的长度不得超过 63 个字符。
SOURCE_LIVESTREAM_URI：直播清单使用公开 URI 或您需要注册了 CDN 密钥
```
AD_TAG_URI
```
默认广告代码的公共 URI。如果没有，您可以使用单个内嵌线性示例。
SLATE_ID：要在无拼接广告时使用的可选广告的 ID

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。

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'
{
  "sourceUri": "SOURCE_LIVESTREAM_URI",
  "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"

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。

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：

@'
{
  "sourceUri": "SOURCE_LIVESTREAM_URI",
  "adTagUri": "AD_TAG_URI",
  "defaultSlate": "projects/PROJECT_NUMBER/locations/LOCATION/slates/SLATE_ID",
  "adTracking": "SERVER",
  "stitchingPolicy": "CUT_CURRENT"
}
'@  | 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/liveConfigs?liveConfigId=LIVE_CONFIG_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,
    "target": "projects/PROJECT_NUMBER/locations/LOCATION/liveConfigs/LIVE_CONFIG_ID",
    "verb": "create",
    "cancelRequested": false,
    "apiVersion": "v1"
  },
  "done": false
}

此命令会创建一个长时间运行的操作 (LRO) 您可以查询该 ID 以跟踪进度。复制返回的 OPERATION_ID（即 name 字段的最后一部分），以便在下一部分中使用。

要检查是否已创建实时配置，请使用 projects.locations.operations.get 方法。如果响应包含 "done: false"，请重复该命令，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；该名称位于 IAM 设置的项目编号字段中页

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）

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：

获取实时配置

如需获取特定实时配置的详细信息，请使用 projects.locations.liveConfigs.get 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；此值位于 IAM 设置页面上的项目编号字段中
LOCATION：实时配置的位置；请使用某个受支持的区域
显示营业地点
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
LIVE_CONFIG_ID：实时配置的用户定义标识符

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

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/liveConfigs/LIVE_CONFIG_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/liveConfigs/LIVE_CONFIG_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/liveConfigs/LIVE_CONFIG_ID",
  "sourceUri": "SOURCE_LIVESTREAM_URI",
  "adTagUri": "AD_TAG_URI",

更新实时配置

要更新特定的活动配置，请使用 projects.locations.liveConfigs.patch 方法。您只能更新自定义标头。

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；该名称位于 IAM 设置页面的项目编号字段中
LOCATION：要在其中创建实时配置的位置；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
LIVE_CONFIG_ID：实时配置的用户定义标识符
KEY：键值对中的键，用于定义自定义标头
VALUE：用于定义自定义标头的键值对中的值

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'
{
  "sourceFetchOptions": {
    "headers": {
      "KEY": "VALUE"
    }
  }
}
EOF

然后，执行以下命令以发送 REST 请求：

curl -X PATCH \
     -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/LIVE_CONFIG_ID?updateMask=sourceFetchOptions.headers"

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。

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：

{
  "sourceFetchOptions": {
    "headers": {
      "KEY": "VALUE"
    }
  }
}
'@  | 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 PATCH `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/liveConfigs/LIVE_CONFIG_ID?updateMask=sourceFetchOptions.headers" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

  "metadata": {
    "@type": "type.googleapis.com/google.cloud.common.OperationMetadata",

    "verb": "update",
    "cancelRequested": false,
    "apiVersion": "v1"
  },
  "done": false
}

此命令会创建一个长时间运行的操作 (LRO)，您可以对其进行查询以跟踪进度。如需了解详情，请参阅检查结果。

列出所有已注册的正式版配置

如需列出项目中为指定位置注册的所有实时配置，请使用 projects.locations.liveConfigs.list 方法。

删除实时配置

如果不再需要已注册的实时配置，请使用 projects.locations.liveConfigs.delete 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；此值位于 IAM 设置页面上的项目编号字段中
LOCATION：实时配置的位置；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
LIVE_CONFIG_ID：实时配置的用户定义标识符

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

执行以下命令：

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/liveConfigs/LIVE_CONFIG_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 DELETE `
    -Headers $headers `
    -Uri "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/liveConfigs/LIVE_CONFIG_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,
    "target": "projects/PROJECT_NUMBER/locations/LOCATION/liveConfigs/LIVE_CONFIG_ID",
    "verb": "delete",
    "cancelRequested": false,
    "apiVersion": "v1"
  },
  "done": false
}

此命令会创建一个长时间运行的操作 (LRO) 您可以查询该 ID 以跟踪进度。如需了解详情，请参阅检查结果。
