Abstract: A method and an apparatus for recording and replaying a video of a terminal are described, which can solve a problem, which is caused by failure to continuously reflect a running status of a program, of low efficiency of recording and replaying the video of the terminal. The method includes: receiving screenshots that are sent by a terminal according to a first preset time interval and performance data of the terminal that is sent by the terminal according to a second preset time interval, wherein the first preset time interval is less than the second preset time interval; synthesizing the received screenshots into video data that has a start time and an end time; and playing, according to a playback time selected by a user, the video data and the performance data corresponding to the playback time.

Abstract: This application relates to a method for transmitting a scene image of a virtual scene. The method includes: rendering a first image to obtain a first rendered image, wherein the first image is obtained through acquisition of display data of a virtual scene when the display data changes; acquiring a first time point at which the rendering of the first image is completed; encoding the first rendered image to obtain an encoded image when an interval between the first time point and a second time point is not less than a first interval threshold, wherein the second time point is a time point at which image encoding is performed last time; and transmitting the encoded image to a terminal for decoding and displaying.
