How python speed up like 100x video, increase FPS of video | with souce code

This chapter aims to document how the author accelerates video playback, such as increasing it by 100 times, it seems cv2 is not able to set 1000 FPS, hence I decided to ignore some frame so as to accelerate the video.

# Importing all necessary libraries
import cv2
import os
import math


def makeVideo(path, video_name):

    # open file
    cam = cv2.VideoCapture(path)
    try:
        if not os.path.exists('data'):
            os.makedirs('data')
    except OSError:
        print('Error: Creating directory of data')

    # get FPS of input video
    fps = cam.get(cv2.CAP_PROP_FPS)
    fps_new = 100
    # 总帧数(frames)
    frames = cam.get(cv2.CAP_PROP_FRAME_COUNT)
   

    height = 0;
    width = 0;
    layers = 0;

    video = cv2.VideoWriter(video_name, 0, fps_new, (int(cam.get(3)), int(cam.get(4))) )
    index = 0;

    allFrames = []
    add = 0
    ttt = 0
    while cam.isOpened():
        text = "index={}".format(index)
        ret, frame = cam.read()
        if not ret:
            break
