Screen projection delay test method and terminal

The invention provides a screen projection delay test method and a terminal. The method comprises the steps of projecting a first screen to a second screen; playing a stopwatch on the first screen, recording the first screen and the second screen to obtain a video file, converting each frame of the video file into a picture, generating a picture list, traversing the picture list, respectively obtaining stopwatch information on a first screen and stopwatch information on a second screen in each frame of picture in the picture list, and obtaining screen projection delay corresponding to each frame of picture according to the stopwatch information on the first screen and the stopwatch information on the second screen; according to the method, the screen projection time delay between the shared screens can be automatically tested, manpower is released, the test efficiency is improved, each frame of picture can be accurately captured to calculate the time delay, the time point of video omission is avoided, and the
