将直播分发到远程端点

本页介绍了如何使用安全可靠传输 (SRT) 协议或实时消息传送协议 (RTMP) 将直播输出分发到远程端点。SRT 和 RTMP 均以推送模式将视频流发送到端点。支持的容器格式为 MPEG-TS（适用于 SRT）和 FLV（适用于 RTMP）。

准备工作

本页面假定您已完成 HLS 直播快速入门的准备工作部分中的步骤。

根据您选择的分发协议，在您希望以推送模式接收输出的提供商处创建 SRT 或 RTMP 端点。端点 URI 格式因协议而异：

对于 SRT： srt://SRT_SERVER_IP:SRT_SERVER_PORT?streamid=SRT_SERVER_STREAM_ID
对于 RTMP： rtmp://RTMP_SERVER_IP:RTMP_SERVER_PORT/RTMP_APP_NAME/RTMP_STREAM_KEY 或仅 rtmp://RTMP_SERVER_IP:RTMP_SERVER_PORT/RTMP_APP_NAME

SRT_SERVER_IP 和 RTMP_SERVER_IP 可以是 IP 地址，也可以是域名。

创建输入端点

如需创建输入端点，请使用 projects.locations.inputs.create 方法。

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：创建输入端点的位置；请使用某个受支持的地区
显示位置
- us-central1
- us-east1
- us-east4
- us-west1
- us-west2
- northamerica-northeast1
- southamerica-east1

- asia-south1
- asia-northeast1
- asia-southeast1
- australia-southeast1
- europe-north1
- europe-west1
- europe-west2
- europe-west3
- europe-west4
INPUT_ID：要创建的新输入端点（您将输入流发送到该端点）的用户定义标识符。此值必须为 1-63 个字符，以 [a-z0-9] 开头和结尾，并且可以在字符之间包含短划线 (-)。例如 my-input。

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'
{
  "type": "RTMP_PUSH"
}
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://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/inputs?inputId=INPUT_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：

@'
{
  "type": "RTMP_PUSH"
}
'@  | 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://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/inputs?inputId=INPUT_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.video.livestream.v1.OperationMetadata",
    "createTime": CREATE_TIME,
    "target": "projects/PROJECT_NUMBER/locations/LOCATION/inputs/INPUT_ID",
    "verb": "create",
    "requestedCancellation": false,
    "apiVersion": "v1"
  },
  "done": false
}

复制返回的 OPERATION_ID 以便在下一部分中使用。

检查结果

使用 projects.locations.operations.get 方法检查是否已创建输入端点。如果响应包含 "done: false"，请重复执行该命令，直到响应包含 "done: true"。在某个区域中创建第一个输入端点最多可能需要 10 分钟。

在使用任何请求数据之前，请先进行以下替换：

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://livestream.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://livestream.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：

    "tier": "HD"
  }
}

找到 uri 字段，然后复制返回的 INPUT_STREAM_URI 以供稍后在发送输入流部分中使用。

创建频道

如需创建渠道，请使用 projects.locations.channels.create 方法。

请注意频道配置中的以下事项：

distributionStreams 数组包含分发的流的多路复用设置。

每个 DistributionStream 对象都必须包含 key、container 和 elementaryStreams 字段。

{
  "distributionStreams": [
    {
      "key": "ds1",
      "container": "ts", // to be used with an SRT distribution
      "elementaryStreams": [
        "es_video_720",
        "es_audio"
      ]
    },
    {
      "key": "ds2",
      "container": "flv", // to be used with an RTMP distribution
      "elementaryStreams": [
        "es_video_640",
        "es_audio"
      ]
    }
  ]
}

distributions 数组列出了分发配置，其中包括远程端点。
将 Distribution 对象中的 distributionStream 字段设置为 DistributionStream 对象的 key。

对于 SRT 分发，请将 SrtPushOutputEndpoint 对象中的 uri 设置为您创建的 SRT 端点。对于 RTMP 分发，请将 RtmpPushOutputEndpoint 对象中的 uri 设置为您创建的 RTMP 端点。

{
  "distributions": [
    {
      "key": "pd1",
      "distributionStream": "ds1", // defined in a distributionStreams[] object with an MPEG-TS container
      "srtPush": {
        "uri": "srt://SRT_SERVER_IP:SRT_SERVER_PORT?streamid=SRT_SERVER_STREAM_ID"
      }
    },
    {
      "key": "pd2",
      "distributionStream": "ds2", // defined in a distributionStreams[] object with an FLV container
      "rtmpPush": {
        "uri": "rtmp://RTMP_SERVER_IP:RTMP_SERVER_PORT/RTMP_APP_NAME/",
        "streamKey": "RTMP_STREAM_KEY"
      }
    }
  ]
}

如需分发 AI 生成的字幕和翻译的字幕，请参阅配置自动字幕和翻译指南。

以下示例仅使用一个 DistributionStream 对象和一个 Distribution 对象。

CHANNEL_ID：用户定义的渠道标识符

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

}

此响应表示频道的流式传输状态和频道分发情况。

如果分发处于 NOT_READY 状态，则无法启动分发。您必须等到状态变为 READY 才能开始分发直播。

创建第一个分发流最多可能需要 10 分钟。分发的状态与渠道状态无关；您可以先启动渠道，等待分发变为 READY，然后再启动分发。

现在，您可以启动频道了。

创建频道

使用 projects.locations.channels.start 方法启动渠道。必须先启动频道，然后才能接受输入流或生成输出流。

在某个区域启动第一个频道大约需要 10 分钟。

SRT 加密支持

如果您使用 SRT 协议将直播输出分发到远程端点，Live Stream API 会使用 AES 加密来保护您的直播内容。

创建口令并准备远程 SRT 服务器

开始之前，请创建符合远程 SRT 服务器要求的 SRT 密码。口令通常应为 10-79 个字符的字符串。

通过在远程 SRT 服务器中设置相同的口令，确保解密过程正常运行。如需了解具体操作方法，请参阅远程 SRT 服务器的用户指南。

将口令添加到 Secret Manager

Live Stream API 不直接接受或管理口令。 您必须通过 Google Secret Manager 与 Live Stream API 共享口令。

您必须先完成所有这些步骤，然后才能配置渠道：

使用 Secret Manager 创建 Secret。
为您的密钥配置 Identity and Access Management 权限，以便 Live Stream API 可以访问密钥内容。为此，请向 service-PROJECT_NUMBER@gcp-sa-livestream.iam.gserviceaccount.com 服务账号授予 secretmanager.secretAccessor 角色（这与服务账号有权访问您的 Cloud Storage 存储分区的方式类似）。
找到您创建的 Secret 版本的资源名称（例如 projects/PROJECT_NUMBER/secrets/SECRET_ID/versions/VERSION_ID）。您需要此名称来配置渠道。

配置渠道

口令的密文版本在 SrtPushOutputEndpoint 中指定：

{
  "distributions": [
    {
      "key": "pd1",
      "distributionStream": "ds1", // defined in a distributionStreams[] object with an MPEG-TS container
      "srtPush": {
        "uri": "srt://{SRT_SERVER_IP}:{SRT_SERVER_PORT}?streamid={SRT_SERVER_STREAM_ID}",
        "passphrase_secret_version": "projects/PROJECT_NUMBER/secrets/key1/versions/1"
      }
    }
  ]
}

清理

为避免因本面页中使用的资源导致您的 Google Cloud 账号产生费用，请按照以下步骤操作。

停止频道

使用 projects.locations.channels.stop 方法停止渠道。您必须先停止频道，然后才能将其删除。
