Créer et gérer des composants

Cette page vous explique comment créer et gérer des composants de l'API Live Stream. Les composants sont des vidéos ou des images pouvant être utilisés avec l'API Live Stream. Vous pouvez utiliser un élément pour insérer un écran de titre dans une diffusion en direct.

Formats multimédias acceptés

L'API Live Stream est compatible avec les codecs et formats multimédias suivants pour les éléments.

Insérer un élément multimédia	Formats compatibles
Formats de fichiers vidéo	MP4, MPEG-TS, FLV
Codecs vidéo	H.264
Codecs audio	AAC, AC3, MP2, MP3
Formats de fichiers image	JPG
Taille maximale	250 Mo
Résolutions maximales	1 920 x 1 080

Configurer votre authentification et votre projet Google Cloud

Si vous n'avez pas encore créé de projet Google Cloud ni d'identifiants, consultez la section Avant de commencer.

Créer un élément

Pour créer un composant, utilisez la méthode projects.locations.assets.create. L'exemple suivant crée un élément vidéo.

REST

Avant d'utiliser les données de requête ci-dessous, effectuez les remplacements suivants :

PROJECT_NUMBER: numéro de votre projet Google Cloud, qui se trouve dans le champ Numéro de projet sur la page Paramètres IAM.
LOCATION: emplacement dans lequel créer l'asset. Utilisez l'une des régions disponibles.
Afficher les emplacements
- us-central1
- us-east1
- us-east4
- us-west1
- us-west2
- northamerica-northeast1
- southamerica-east1
- asia-east1
- asia-east2
- asia-south1
- asia-northeast1
- asia-southeast1
- australia-southeast1
- europe-north1
- europe-west1
- europe-west2
- europe-west3
- europe-west4
ASSET_ID: identifiant défini par l'utilisateur pour le nouvel élément à créer. Cette valeur doit comporter entre 1 et 63 caractères, commencer et se terminer par [a-z0-9], et peut contenir des tirets (-) entre les caractères. Par exemple, my-asset.
ASSET_URI: URI de la vidéo dans votre bucket Cloud Storage à utiliser, par exemple gs://my-bucket/my-video.mp4 (voir les formats multimédias compatibles)

Pour envoyer votre requête, développez l'une des options suivantes :

curl (Linux, macOS ou Cloud Shell)

Remarque : La commande suivante suppose que vous êtes connecté à la CLI gcloud avec votre compte utilisateur en exécutant la commande gcloud init ou gcloud auth login, ou en utilisant Cloud Shell, qui vous connecte automatiquement à la CLI gcloud. Vous pouvez exécuter la commande gcloud auth list pour vérifier quel est le compte actuellement actif.

Enregistrez le corps de la requête dans un fichier nommé request.json. Exécutez la commande suivante dans le terminal pour créer ou écraser ce fichier dans le répertoire actuel :

cat > request.json << 'EOF'
{
  "video": {
    "uri": "ASSET_URI"
  }
}
EOF

Exécutez ensuite la commande suivante pour envoyer votre requête REST :

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/assets?assetId=ASSET_ID"

PowerShell (Windows)

Remarque : La commande suivante suppose que vous vous êtes connecté à la CLI gcloud avec votre compte utilisateur en exécutant la commande gcloud init ou gcloud auth login. Vous pouvez exécuter la commande gcloud auth list pour vérifier quel est le compte actuellement actif.

Enregistrez le corps de la requête dans un fichier nommé request.json. Exécutez la commande suivante dans le terminal pour créer ou écraser ce fichier dans le répertoire actuel :

@'
{
  "video": {
    "uri": "ASSET_URI"
  }
}
'@  | Out-File -FilePath request.json -Encoding utf8

Exécutez ensuite la commande suivante pour envoyer votre requête REST :

$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/assets?assetId=ASSET_ID" | Select-Object -Expand Content

Vous devriez recevoir une réponse JSON de ce type :

{
