ジョブテンプレートの作成と管理

このページでは、Transcoder API のジョブテンプレートを作成して管理する方法について説明します。

デフォルトでは、Transcoder API は、preset/web-hd という既成のテンプレートを適用してジョブ構成を設定します。コード変換ジョブを作成する際は、独自のカスタムジョブテンプレートを指定できます。ジョブ構成には、ジョブの作成時にカスタマイズできる多くの設定が記述されます。

Google Cloud プロジェクトと認証の設定

Google Cloud プロジェクトと認証情報を作成していない場合は、始める前にをご覧ください。

ジョブテンプレートの作成

ジョブテンプレートにはさまざまな設定を行えます。ジョブ設定の用語とコンセプトの概要については、Transcoder API の概要をご覧ください。

ジョブテンプレートを作成するには、projects.locations.jobTemplates.create メソッドを使用します。次の例では、簡単な構成を使用して標準解像度と高解像度の .mp4 出力ファイルを作成します。ジョブ構成の詳細については、JobConfig リファレンスをご覧ください。

REST

リクエストのデータを使用する前に、次のように置き換えます。

PROJECT_ID: IAM 設定に載っている Google Cloud プロジェクト ID。
LOCATION: ジョブテンプレートを保存するロケーション。サポートされているリージョンのいずれかを使用します。

TEMPLATE_ID: 作成する新しいジョブテンプレートのユーザー定義 ID。この値は 4～63 文字で、正規表現 [a-zA-Z][a-zA-Z0-9_-]* で有効な文字を指定します。

リクエストを送信するには、次のいずれかのオプションを展開します。

curl（Linux、macOS、Cloud Shell）

注: 次のコマンドは、gcloud init または gcloud auth login を実行して、ユーザーアカウントで gcloud CLI にログインしているか、Cloud Shell を使用して自動的に gcloud CLI にログインしていることを前提としています。gcloud auth list を実行すると、現在アクティブなアカウントを確認できます。

リクエスト本文を request.json という名前のファイルに保存します。ターミナルで次のコマンドを実行して、このファイルを現在のディレクトリに作成または上書きします。

cat > request.json << 'EOF'

    "elementaryStreams": [

        ]
      }
    ]
  }
}

その後、次のコマンドを実行して REST リクエストを送信します。

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
