Si les modèles prédéfinis d'ApsaraVideo Media Processing ne répondent pas à vos besoins, créez des modèles de transcodage personnalisés en définissant des paramètres tels que le format d'encodage, la fréquence d'images et la résolution. Les exemples suivants, basés sur le SDK Java V2.0, illustrent comment ajouter, mettre à jour, supprimer et interroger des modèles de transcodage.
Prérequis
Initialisez le client avant de commencer. Pour plus d'informations, consultez la rubrique Initialisation.
Ajouter un modèle
Appelez l'opération AddTemplate pour ajouter un modèle.
Remarque
Si le message d'erreur
The resource "Template" quota has been used ups'affiche lors de l'ajout d'un modèle, votre quota de modèles de transcodage est atteint. Soumettez un ticket pour demander une augmentation de quota.Notez l'ID du modèle de transcodage renvoyé après l'ajout. Vous pouvez également créer et gérer des modèles de transcodage directement depuis la console. Pour en savoir plus, consultez la rubrique Modèles de transcodage.
