プロジェクトで Video Stitcher API を有効にするには、アカウント担当者または営業担当者に詳細をお問い合わせください。

VOD アセットに広告を挿入する

このページでは、Video Stitcher API と curl、PowerShell、またはクライアントライブラリを使用して、VOD（ビデオオンデマンド）アセットの再生に広告を挿入する方法について説明します。

始める前に

Video Stitcher API を呼び出す前に、次の手順を行います。

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

Install the Google Cloud CLI.

To initialize the gcloud CLI, run the following command:

gcloud init

Create or select a Google Cloud project.

Create a Google Cloud project:
```
gcloud projects create PROJECT_ID
```
Replace PROJECT_ID with a name for the Google Cloud project you are creating.
Select the Google Cloud project that you created:
```
gcloud config set project PROJECT_ID
```
Replace PROJECT_ID with your Google Cloud project name.

Make sure that billing is enabled for your Google Cloud project.

Enable the Video Stitcher API:

gcloud services enable videostitcher.googleapis.com

If you're using a local shell, then create local authentication credentials for your user account:

gcloud auth application-default login

You don't need to do this if you're using Cloud Shell.

Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/videostitcher.admin

gcloud projects add-iam-policy-binding PROJECT_ID --member="USER_IDENTIFIER" --role=ROLE

Replace PROJECT_ID with your project ID.
Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.
Replace ROLE with each individual role.

Install the Google Cloud CLI.

To initialize the gcloud CLI, run the following command:

gcloud init

Create or select a Google Cloud project.

Create a Google Cloud project:
```
gcloud projects create PROJECT_ID
```
Replace PROJECT_ID with a name for the Google Cloud project you are creating.
Select the Google Cloud project that you created:
```
gcloud config set project PROJECT_ID
```
Replace PROJECT_ID with your Google Cloud project name.

Make sure that billing is enabled for your Google Cloud project.

Enable the Video Stitcher API:

gcloud services enable videostitcher.googleapis.com

If you're using a local shell, then create local authentication credentials for your user account:

gcloud auth application-default login

You don't need to do this if you're using Cloud Shell.

Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/videostitcher.admin

gcloud projects add-iam-policy-binding PROJECT_ID --member="USER_IDENTIFIER" --role=ROLE

Replace PROJECT_ID with your project ID.
Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.
Replace ROLE with each individual role.

このクイックスタートには、MPEG-DASH マニフェスト（MPD）ファイルまたは HTTP Live Streaming（HLS）マニフェスト（M3U8）ファイルと、関連するセグメントファイルが必要です。既存の VOD ファイルを使用することも、Transcoder API を使用して VOD ソースファイルを作成することもできます。
オプションとして、このクイックスタートではコンテンツ配信ネットワーク（CDN）を使用できます。CDN を構成していない場合は、メディア CDN のクイックスタートの手順に沿って次の変更を加えます。
1. MPEG-DASH または HLS マニフェストファイルとメディアセグメントを Cloud Storage バケットにアップロードします。
2. Cloud Storage バケットを一般公開にする必要はありません。
3. 署名付き URL または署名なし URLを使用できます。

CDN キーを作成する

Video Stitcher API では、コンテンツ配信ネットワーク（CDN）から動画を取得できます。動画アセットが URL 署名で保護されている場合は、Video Stitcher API で CDN キーを登録する必要があります。

CDN キーを登録するには、projects.locations.cdnKeys.create メソッドを使用します。

結果を確認する

CDN キーが作成されたかどうかを確認するには、projects.locations.operations.get メソッドを呼び出します。レスポンスに "done: false" が含まれている場合は、レスポンスに "done: true" が含まれるまでコマンドを繰り返します。

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_NUMBER: IAM 設定ページの [プロジェクト番号] フィールドにある Google Cloud プロジェクト番号
LOCATION: データのロケーション。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。
ロケーションを表示
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
OPERATION_ID: オペレーションの ID。

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開きます。

curl（Linux、macOS、Cloud Shell）

次のコマンドを実行します。

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID"

PowerShell（Windows）

次のコマンドを実行します。

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID" | Select-Object -Expand Content

VOD_CONFIG_ID: VOD 構成のユーザー定義の識別子。この ID に使用できるのは、小文字、数字、ハイフンに限られます。最初の文字は英字で、最後の文字は英字または数字で、ID 全体は最大 63 文字です。
VOD_URI: 合成するメディアの URI。この URI は、MPEG-DASH マニフェスト（MPD）ファイルまたは HLS マニフェスト（M3U8）ファイルを参照する必要があります。CDN キーを登録した公開 URI または署名なし URI を使用します。
注: Transcoder API を使用して、これらのマニフェストファイルを作成できます。詳しくは、VOD ソースファイルを作成するをご覧ください。マニフェストファイルを公開して、Video Stitcher API がアクセスできるようにする必要があります。
```
AD_TAG_URI
```
: 広告タグの公開 URI。ない場合は、VMAP プレロールサンプルを使用できます。

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）

cat > request.json << 'EOF'
{
  "sourceUri": "VOD_URI",
  "adTagUri": "AD_TAG_URI"
}
EOF

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 \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/vodConfigs?vodConfigId=VOD_CONFIG_ID"

PowerShell（Windows）

@'
{
  "sourceUri": "VOD_URI",
  "adTagUri": "AD_TAG_URI"
}
'@  | Out-File -FilePath request.json -Encoding utf8

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。

$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

次のような JSON レスポンスが返されます。

Video Stitcher API は、リクエストごとに一意のセッション ID を生成します。セッションは 4 時間後に期限切れになります。

広告の挿入を確認する

VOD セッションに広告を合成する前にエンコードする必要があります。

vodSessions.create コマンドで指定した広告がすでに前のセッションからエンコードされている場合、Video Stitcher API の JSON レスポンスに adBreaks イベントが含まれます。Video Stitcher API は、Google Cloud プロジェクトに関連付けられたセッションによって作成されたエンコード済みの広告のみを検索します。

広告がまだエンコードされていない場合、JSON レスポンスには adBreaks イベントが含まれません。前のセクションのような JSON レスポンスを受け取った場合は、広告がエンコードされるまで待機してから、vodSessions.create コマンドを再実行します。

エンコードされた広告が正常にセッションに合成されると、レスポンスは次のようになります。

{

  "interstitials": {
    "adBreaks": [
