s301, dynamically calculating the frame loading condition of each layer on the current mobile phone by the mobile phone terminal;

specifically, under normal conditions, when the screen projection is started, the mobile phone pops up a small dot of a pixel, the name title of the small dot is a window of a, and the frame-up frame projection frame rate of the small dot is stabilized at 60HZ according to a Vsync (frame synchronization) signal of the current mobile phone. In this embodiment, when a Vysnc (frame synchronization) signal comes, a layer where a small circle point is located is determined according to a small circle point title, if the small circle point is counted as numA + + (numA marks are in a statistical range, when Vyscn comes this time, the small circle point layer has a previous frame and marks a statistical value), and when other layer has a previous frame, a numB + + statistical operation is performed (numB marks are in a statistical range, and when Vyscn comes this time, other layer has a previous frame and marks a statistical value).

S302, a scalar flag is defined in the surfaceflag layer, and the scalar flag is used for marking the screen projection according to the upper frame condition of which layer.

The method specifically comprises the following steps:

s3021, comparing the upper frame data statistic numA of the layer where the small circle is located with the upper frame data statistic numB of other layer to determine the actual screen projection frame rate;
