O recurso de snapshot de vídeo permite capturar imagens de tamanho específico em momentos determinados. Essas imagens são úteis para gerar miniaturas de vídeo, sprites e miniaturas da barra de progresso. Especifique os momentos exatos da captura, o intervalo entre snapshots consecutivos, a quantidade total de imagens, os tipos desejados e se elas devem ser combinadas em um único sprite. Este tópico apresenta um exemplo de uso do ApsaraVideo Media Processing (MPS) SDK for PHP V2.0 para essa tarefa.
