Here's my code - I've a lot to learn so any advice, tips etc would be welcome! A few notes: I'm using OpenCV and numpy for other features in this code, not just for this snippet. The main readon for making frameDelay a class was as a way of passing another variable into the on_press function The weird infinite while loop in the delay function was so I could have a delay which could change length whilst in the actual delay.
While (((time.time() - starttime)*1000) < self.wait):
The above code didn't work as I wished. In the case of a long wait time, it would take that long before the delay length could be changed. I expect there is a better way!
As I said, here's the code! Thanks for looking.
import cv2
from pynput import mouse
import time
import numpy as np
class frameDelay:
def __init__(self):
#set up initial values
self.lasttime=time.time() #time since last click
self.times=[0,0] #list of last two click intervals
self.wait=30000 #initial frame delay
def on_press(self,x, y, button, pressed):
if pressed:
self.times.append(time.time() - self.lasttime) #add time since last click to right of times[]
self.times.pop(0) #delete oldest value
self.wait = (((self.times[0] + self.times[1])/2)*50) #average two values
self.wait = int(np.clip (self.wait,1,500)) #convert to int between 10 and 100
self.lasttime = time.time() #start timer
def delay(self):
#wait for self.wait ms
starttime=time.time()
while True:
if (((time.time() - starttime)*1000) > self.wait):
break
time.sleep(0.001)
def increment(self, x):
#increase the wait variable - slow down if no clicks.
self.wait += x
def main():
fd = frameDelay()
listener = mouse.Listener(
on_click=fd.on_press)
listener.start()
#open video file
cap = cv2.VideoCapture("/Users/regvardy/mediapipe_faceswap-main/webcam_grab.mov")
while(cap.isOpened()):
ret, frame = cap.read()
cv2.waitKey(1)
fd.delay()
fd.increment(30)
cv2.imshow('frame',frame)
cap.release()
cv2.destroyAllWindows()
if __name__ == "__main__":
main()
