创建和管理 VOD 配置

本页介绍了如何管理 VOD 配置。VOD 配置用于配置 VOD 会话。如需了解详情，请参阅 REST 文档。

准备工作

如需创建 VOD 会话，您必须先配置一个编码器，该编码器会为 VOD 资源生成源 HLS 或 DASH 清单。这些清单在广告插播边界处包含某些广告标记，Video Stitcher API 会识别这些标记以用于广告拼接。您可以使用 Transcoder API 创建转码作业，以从 媒体文件类型（例如 MP4 或 MOV）生成清单文件。

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。

定义 VOD 配置

定义 VOD 配置时，需要提供以下字段：

• sourceUri
• adTagUri

sourceUri 指定源 VOD 资产的 HLS 或 DASH 清单的网址，以便将广告插入其中。如果提供的网址引用的是 HLS 清单，Video Stitcher API 会返回 HLS 播放网址；如果提供的网址引用的是 DASH 清单，Video Stitcher API 会返回 DASH 播放网址。您可以使用现有的清单文件，也可以创建自己的 VOD 源文件。

adTagUri 指定返回广告元数据的广告服务器的网址。

VOD 配置包含一个用于定义自定义标头的可选字段。

注册 VOD 配置

如需注册 VOD 配置，请使用 projects.locations.vodConfigs.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：用于创建视频点播配置的位置；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
• VOD_CONFIG_ID：用户定义的 VOD 配置标识符。 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 最多包含 63 个字符。
• VOD_URI：要拼接的媒体的 URI。此 URI 必须引用 MPEG-DASH 清单 (MPD) 文件或 HLS 清单 (M3U8) 文件。使用您注册了 CDN 密钥的公开 URI 或未签名 URI。
  注意：您可以使用 Transcoder API 创建这些清单文件。如需了解详情，请参阅创建 VOD 源文件。您必须将清单文件设为公开，以便 Video Stitcher API 可以访问这些文件。
• 广告代码的公开 URI；如果没有，您可以使用 VMAP 预贴片广告示例

  AD_TAG_URI

请求 JSON 正文：

{
  "sourceUri": "VOD_URI",
  "adTagUri": "AD_TAG_URI"
}

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": "VOD_URI",
  "adTagUri": "AD_TAG_URI"
}
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/vodConfigs?vodConfigId=VOD_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": "VOD_URI",
  "adTagUri": "AD_TAG_URI"
}
'@  | 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/vodConfigs?vodConfigId=VOD_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/vodConfigs/VOD_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)，您可以查询该操作来跟踪进度。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。

更新 VOD 配置

如需更新 VOD 配置，请使用 projects.locations.vodConfigs.patch 方法。以下示例更新了 sourceUri 字段。

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：视频点播配置的位置；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
• VOD_CONFIG_ID：用户定义的视频点播配置标识符
• VOD_URI：要拼接的媒体的更新 URI

请求 JSON 正文：

{
  "sourceUri": "VOD_URI"
}

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": "VOD_URI"
}
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/vodConfigs/VOD_CONFIG_ID?updateMask=sourceUri"

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": "VOD_URI"
}
'@  | 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/vodConfigs/VOD_CONFIG_ID?updateMask=sourceUri" | 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/vodConfigs/VOD_CONFIG_ID",
    "verb": "update"
  },
  "done": false
}

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