Abstract

Un procédé et un appareil de prévisualisation de vidéo, et un support de stockage et un dispositif électronique sont fournis. Le procédé fait appel aux étapes suivantes : en réponse à une opération d'un utilisateur pour faire glisser une interface utilisateur, la détection quant au faut de savoir si un élément qui satisfait à une condition de prévisualisation prédéterminée change ; en cas de changement, après que le glissement de l'interface utilisateur s'arrête, l'arrêt du contenu vidéo de prévisualisation d'un premier élément sur l'interface utilisateur, et la libération d'un premier lecteur utilisé pour prévisualiser le contenu vidéo, le premier élément étant un élément prévisualisé avant le changement ; et la création d'un second lecteur, et l'utilisation du second lecteur pour prévisualiser le contenu vidéo d'un second élément sur l'interface utilisateur, le second élément étant un élément prévisualisé après le changement. Au moyen de l'utilisation des modes de réalisation de la présente divulgation, pendant l'utilisation par l'utilisateur, le processus de réponse à l'opération de glissement est traité de manière préférentielle, de sorte qu'aucune mise en mémoire tampon n'apparaisse sur l'interface d'UI, et la régularité est meilleure.
