Abstract
(EN)
Embodiments of the application disclose a video decoding control method and device, and an electronic device. The method includes steps: when it is detected that multiple application programs operatein a split screen mode, detecting application programs in the video playing state in the multiple application programs; obtaining the detected application programs in the video playing state as to-be-configured application programs; and configuring videos played for decoding the to-be-configured application programs in a hard decoding mode. According to the method, when the multiple application programs are in the split screen display mode and several application programs in the multiple application programs have the video playing function, and the videos played for decoding the application programs in the video playing state in the hard decoding mode are configured so that the load rate of a CPU is reduced, the CPU has more processing capabilities to deal with other tasks, the probabilityof lagging of the electronic device is reduced, and the user experience is enhanced.

本申请实施例公开了一种视频解码控制方法、装置以及电子设备。所述方法包括:当检测到多个应用程序以分屏模式运行后,检测所述多个应用程序中处于视频播放状态的应用程序;获取检测到的处于视频播放状态的应用程序作为待配置应用程序;配置以硬解码的方式解码所述待配置应用程序所播放的视频。本方法通过在多个应用程序处于分屏显示模式下,并且在多个应用程序中有多个应用程序均具备视频播放功能的情况下,会配置以硬解码的方式对处于视频播放状态的应用程序所播放的视频进行解码,进而降低CPU的负载率,进而使得CPU有更多的处理能去处理其他的任务,降低电子设备处于卡顿的概率,从而提升用户体验。
