Se os modelos predefinidos do ApsaraVideo Media Processing não atenderem às suas necessidades, crie modelos de transcodificação personalizados com parâmetros como formato de codificação, taxa de quadros e resolução. Os exemplos a seguir com o SDK Java V2.0 demonstram como adicionar, atualizar, excluir e consultar modelos de transcodificação.
Pré-requisitos
Inicialize o cliente antes de começar. Para mais informações, consulte Inicialização.
Adicionar um modelo
Chame a operação AddTemplate para adicionar um modelo.
Nota
Caso receba o erro
The resource "Template" quota has been used upao adicionar um modelo, sua cota de modelos de transcodificação foi esgotada. Envie um ticket envie um ticket para solicitar um aumento de cota.Anote o ID do modelo de transcodificação retornado após a adição do modelo. Também é possível criar e gerenciar modelos de transcodificação no console. Para mais informações, consulte Modelos de transcodificação.
