Abstract:
(EN) Disclosed in the application are a rendering method, a decoding method, and a method and device for playing a multimedia data stream. The rendering method comprises: if it is determined that parsing of at least one image of a multimedia data stream has been completed, drawing a transparent area on an interface, and instructing drawing of a playing window for the multimedia data stream and the at least one image of the multimedia data stream; and superimposing the transparent area and the playing window onto different drawing layers. The application can solve a problem of screen color distortion occurring easily when multimedia data starts to be played in the drawn transparent area.
(FR) La présente invention concerne un procédé de rendu, un procédé de décodage, ainsi qu'un procédé et un dispositif pour lire un flux de données multimédias. Le procédé de rendu consiste à : s’il est déterminé que l’analyse d’au moins une image d’un flux de données multimédias a été achevée, dessiner une zone transparente sur une interface, et ordonner le dessin d’une fenêtre de lecture pour le flux de données multimédias et la ou les images du flux de données multimédias ; et superposer la zone transparente et la fenêtre de lecture sur différentes couches de dessin. La présente invention peut résoudre un problème de déformation de couleur d’écran se produisant facilement lorsque des données multimédias commencent à être lues dans la zone transparente dessinée.
(ZH) 本申请公开了渲染方法、解码方法、播放多媒体数据流的方法及装置、设备。渲染方法包括:如果判断已解析完多媒体数据流的至少一帧图像,则绘制界面上的透明区域,并指示进行所述多媒体数据流的播放窗口和所述多媒体数据流的至少一帧图像的绘制,所述透明区域和所述播放窗口重叠于不同的绘图层。本申请能够解决多媒体数据透过绘制好的透明区域开始播放时容易产生的"花屏"现象。
