创建和管理作业模板

本页面介绍了如何创建和管理 Transcoder API 作业模板。

默认情况下，Transcoder API 会应用名为 preset/web-hd 的预设模板来填充作业配置。您可以在创建转码作业时指定自己的自定义作业模板。作业配置表示您在创建作业时可以自定义的许多设置。

设置您的 Google Cloud 项目和身份验证

如果您尚未创建 Google Cloud 项目和凭据，请参阅准备工作。

创建作业模板

您可以在作业模板中指定各种设置。如需了解作业配置的一些术语和概念，请参阅 Transcoder API 概览。

如需创建作业模板，请使用 projects.locations.jobTemplates.create 方法。以下示例使用简单配置来创建标清和高清 .mp4 输出文件。如需详细了解作业配置，请参阅 JobConfig 参考文档。

REST

在使用任何请求数据之前，请先进行以下替换：

PROJECT_ID：IAM 设置中列出的 Google Cloud 项目 ID。
LOCATION：作业模板的存储位置。请使用任一支持的区域。
显示位置
- us-central1
- us-west1
- us-west2
- us-east1
- us-east4
- southamerica-east1
- northamerica-northeast1
- asia-east1
- asia-northeast1
- asia-northeast3
- asia-south1
- asia-southeast1
- australia-southeast1
- europe-west1
- europe-west2
- europe-west4
TEMPLATE_ID：要创建的新作业模板的用户定义标识符。此值应为 4-63 个字符，有效字符在正则表达式 [a-zA-Z][a-zA-Z0-9_-]* 中。

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'
{
  "config": {
    "elementaryStreams": [
      {
        "key": "video-stream0",
        "videoStream": {
          "h264": {
            "heightPixels": 360,
            "widthPixels": 640,
            "bitrateBps": 550000,
            "frameRate": 60
          }
        }
      },
      {
        "key": "video-stream1",
        "videoStream": {
          "h264": {
            "heightPixels": 720,
            "widthPixels": 1280,
            "bitrateBps": 2500000,
            "frameRate": 60
          }
        }
      },
      {
        "key": "audio-stream0",
        "audioStream": {
          "codec": "aac",
          "bitrateBps": 64000
        }
      }
    ],
    "muxStreams": [
      {
        "key": "sd",
        "container": "mp4",
        "elementaryStreams": [

          "audio-stream0"
        ]
      }
    ]
  }
}
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://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobTemplates?jobTemplateId=TEMPLATE_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：

gcloud

创建一个定义作业模板字段的 request.json 文件。以下是示例作业模板：

{
  "config": {
    "elementaryStreams": [
      {
        "key": "video-stream0",
        "videoStream": {
          "h264": {
            "heightPixels": 360,
            "widthPixels": 640,
            "bitrateBps": 550000,
            "frameRate": 60
          }
        }
      },
      {
        "key": "video-stream1",
        "videoStream": {
          "h264": {
            "heightPixels": 720,
            "widthPixels": 1280,
            "bitrateBps": 2500000,
            "frameRate": 60
          }
        }
      },
      {
        "key": "audio-stream0",
        "audioStream": {
          "codec": "aac",
          "bitrateBps": 64000
        }
      }
    ],
    "muxStreams": [
      {
        "key": "sd",
        "container": "mp4",
        "elementaryStreams": [
          "video-stream0",
          "audio-stream0"
        ]
      },
      {
        "key": "hd",
        "container": "mp4",
        "elementaryStreams": [
          "video-stream1",
          "audio-stream0"
        ]
      }
    ]
  }
}

对 gcloud 命令进行以下替换：

TEMPLATE_ID：要创建的新作业模板的用户定义标识符。此值应为 4-63 个字符，有效字符在正则表达式 [a-zA-Z][a-zA-Z0-9_-]* 中。
LOCATION：作业模板的存储位置。请使用其中一个受支持的区域。

运行以下命令：

如需向 Transcoder API 进行身份验证，请设置应用默认凭据。如需了解详情，请参阅为本地开发环境设置身份验证。

# project_id  = "YOUR-GOOGLE-CLOUD-PROJECT"  # (e.g. "my-project")
# location    = "YOUR-JOB-TEMPLATE-LOCATION"  # (e.g. "us-central1")

# Require the Transcoder client library.
require "google/cloud/video/transcoder"

# Create a Transcoder client.
client = Google::Cloud::Video::Transcoder.transcoder_service

# Build the resource name of the parent.

# Get the list of job templates.
response = client.list_job_templates parent: parent

puts "Job templates:"
# Print out all job templates.
response.each do |job_template|
  puts job_template.name
end

此响应可能包含 nextPageToken，可用于检索其他结果：

{
  "jobTemplates": [
    ...
  ],
  "nextPageToken": "NEXT_PAGE_TOKEN"
}

在以下 curl 示例中，您可以发送另一个请求，并添加 NEXT_PAGE_TOKEN 的值以列出其他作业模板，类似以下内容：

curl -X GET \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
https://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobTemplates?pageToken=NEXT_PAGE_TOKEN

如需详细了解如何使用此令牌，请参阅相关的客户端库。

删除作业模板

如需删除作业模板，请使用 projects.locations.jobTemplates.delete 方法。

REST

在使用任何请求数据之前，请先进行以下替换：

TEMPLATE_ID：您创建的作业模板的 ID。

PROJECT_ID：您的 Google Cloud 项目 ID。

LOCATION：您的作业模板的位置。请使用其中一个受支持的区域。

显示位置

us-central1
us-west1
us-west2
us-east1
us-east4
southamerica-east1
northamerica-northeast1
asia-east1
asia-northeast1
asia-northeast3
asia-south1
asia-southeast1
australia-southeast1
europe-west1
europe-west2
europe-west4

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://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobTemplates/TEMPLATE_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://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobTemplates/TEMPLATE_ID" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

{}

gcloud

对 gcloud 命令进行以下替换：

TEMPLATE_ID：您创建的作业模板的 ID。
LOCATION：您的作业模板的位置。请使用其中一个受支持的区域。
显示位置
- us-central1
- us-west1
- us-west2
- us-east1

- asia-northeast3
- asia-south1
- asia-southeast1
- australia-southeast1
- europe-west1
- europe-west2
- europe-west4

运行以下命令：

gcloud transcoder templates delete TEMPLATE_ID --location=LOCATION

您应该会看到如下所示的响应：

Deleted template [projects/PROJECT_ID/locations/LOCATION/jobTemplates/TEMPLATE_ID].
