Cloud mobile phone response rendering stage time delay measurement method and device

The invention discloses a cloud mobile phone response rendering stage time delay measurement method and device. The method comprises the steps of acquiring video frames, video frame timestamps corresponding to the video frames and video frame serial numbers; obtaining a video frame serial number of the selected video frame, and then extracting the video frame with the same serial number as the selected video frame from each video frame as a first video frame; wherein the selected video frame is a first frame of video which is selected by a user after analyzing each video frame through preset video analysis software and is generated when the cloud mobile phone terminal responds to the first operation event; and obtaining a first operation event timestamp generated when the cloud mobile phone terminal receives the first operation event, extracting a first video frame timestamp of the first video frame from the video frame timestamps, and then calculating the time delay of the cloud mobile phone in a response re
