创建和管理作业

本页面介绍了如何创建和管理 Transcoder API 作业。

作业表示使用 Transcoder API 管理工作的基本单元。向 Transcoder API 提交作业时，请指定应在哪个地理位置处理作业。您可以列出一个区域中的所有作业。

如需详细了解如何跨地理区域处理作业和相关 Google Cloud 资源，请参阅区域。

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

您可以使用预设的作业模板或已创建的自定义作业模板来创建作业。如需了解如何创建作业模板，请参阅创建和管理作业模板。除了使用模板以外，您还可以在请求中创建作业并直接发送作业的配置。

Transcoder API 支持两种作业模式：交互式和批量。以下部分介绍了如何在交互模式下启动作业。如需以批处理模式启动作业，您必须设置一个额外的字段（如需了解详情，请参阅批处理作业）。

注意：作业将在完成后的 30 天内自动删除（默认情况下）。如需更改此时间，请在 Job 资源中设置 ttlAfterCompletionDays 字段。

根据预设创建作业

要创建作业，请使用 projects.locations.jobs.create 方法。作业将转码为以对象形式存储在 Cloud Storage 中的媒体文件。

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：运行作业的位置。使用某个受支持的区域。
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
STORAGE_BUCKET_NAME：您创建的 Cloud Storage 存储分区的名称。
STORAGE_INPUT_VIDEO：您要对其进行转码的 Cloud Storage 存储分区中的视频的名称，例如 my-vid.mp4。此字段应考虑您在存储分区中创建的任何文件夹（例如 input/my-vid.mp4）。
注意：输入视频必须至少包含一个视频轨道和一首音轨，才可使用 preset/web-hd 预设。
STORAGE_OUTPUT_FOLDER：您要在其中保存已编码视频输出的 Cloud Storage 文件夹名称。
注意：您无需在创建作业之前创建输出文件夹对象。处理作业时，Transcoder API 会自动前置您指定的文件夹名称，作为保存到 Cloud Storage 的对象名称的一部分。

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'
{
  "inputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO",
  "outputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/",
  "templateId": "preset/web-hd"
}
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/jobs"

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：

@'
{
  "inputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO",
  "outputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/",
  "templateId": "preset/web-hd"
}
'@  | 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://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs" | Select-Object -Expand Content

根据作业模板创建作业

如果您已在某个位置创建至少一个作业模板，则可以在发送请求时指定作业模板，以在该位置创建 Transcoder API 作业。

要创建作业，请使用 projects.locations.jobs.create 方法。

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：运行作业的位置。使用某个受支持的区域。
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
STORAGE_BUCKET_NAME：您创建的 Cloud Storage 存储分区的名称。
STORAGE_INPUT_VIDEO：您要对其进行转码的 Cloud Storage 存储分区中的视频的名称，例如 my-vid.mp4。此字段应考虑您在存储分区中创建的任何文件夹（例如 input/my-vid.mp4）。
STORAGE_OUTPUT_FOLDER：您要在其中保存已编码视频输出的 Cloud Storage 文件夹名称。
注意：您无需在创建作业之前创建输出文件夹对象。处理作业时，Transcoder API 会自动前置您指定的文件夹名称，作为保存到 Cloud Storage 的对象名称的一部分。
TEMPLATE_ID：您创建的作业模板的 ID。如果您没有指定自定义作业模板，Transcoder API 会使用 preset/web-hd 作业模板。

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'
{
  "inputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO",
  "outputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/",
  "templateId": "TEMPLATE_ID"
}
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/jobs"

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：

@'
{
  "inputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO",
  "outputUri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/",
  "templateId": "TEMPLATE_ID"
}
'@  | 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://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs" | Select-Object -Expand Content

该响应类似于在使用默认模板创建作业时返回的响应。

使用临时配置创建作业

您可以为包含创建作业的请求的作业发送一个临时配置。

要创建作业，请使用 projects.locations.jobs.create 方法。

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：运行作业的位置。使用某个受支持的区域。
显示营业地点
- us-central1
- us-west1
- us-west2

STORAGE_BUCKET_NAME：您创建的 Cloud Storage 存储分区的名称。
STORAGE_INPUT_VIDEO：您要对其进行转码的 Cloud Storage 存储分区中的视频的名称，例如 my-vid.mp4。此字段应考虑您在存储分区中创建的任何文件夹（例如 input/my-vid.mp4）。
STORAGE_OUTPUT_FOLDER：您要在其中保存已编码视频输出的 Cloud Storage 文件夹名称。
注意：您无需在创建作业之前创建输出文件夹对象。处理作业时，Transcoder API 会自动前置您指定的文件夹名称，作为保存到 Cloud Storage 的对象名称的一部分。

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'

然后，执行以下命令以发送 REST 请求：

curl -X POST \

     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \

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：

获取作业详情

如需检查作业详情或作业状态，请使用 projects.locations.jobs.get 方法。

REST

在使用任何请求数据之前，请先进行以下替换：

JOB_ID：您创建的作业的 ID。

PROJECT_ID：您的 Google Cloud 项目 ID。

LOCATION：您的作业的位置。请使用其中一个受支持的区域。

显示营业地点

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://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs/JOB_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://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs/JOB_ID" | Select-Object -Expand Content

过滤结果

您可以过滤列出作业方法的结果。例如，运行以下 curl 命令可列出所有活动的作业：

curl -X GET \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
'https://transcoder.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs?filter=-state="FAILED"+AND+-state="SUCCEEDED"'

此命令使用求反运算符列出未失败的作业和未成功的作业。生成的列表包含正在运行或待处理的作业（如需了解作业状态，请参阅 ProcessingState）。

以下是一些示例过滤条件：

?filter=state="FAILED"+OR+state="SUCCEEDED"：列出已完成的作业
?filter=createTime+>+"2021-06-09T19:25:21.007649960Z"：列出在特定时间戳之后创建的作业
?filter=inputUri="gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO"：列出具有特定输入 URI 的作业
?filter=config.output.uri="gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/"：列出具有特定输出 URI 的作业

如需了解详情，请参阅 AIP-160 - 过滤。

如需删除作业，请使用 projects.locations.jobs.delete 方法：

注意：作业将在完成后的 30 天内自动删除（默认情况下）。如需更改此时间，请在 Job 资源中设置 ttlAfterCompletionDays 字段。
