Screen Recorder in Python 

:)

:D

How to fix that?

@@PythonicMind idk, it's been a year. but i'd say remove the waitkey() line, or make sure you're writing to the video at the same fps as you're recording screenshots The 20.0 specifies the video render fps. If he actually captures 120 fps like he intended to, the video would play 1/6th speed. But it's faster because the loop is slow. it might also be that taking screenshots in this way isn't the best way to record a high fps video.

@@Djellowman I fixed that. Thanks.

@@PythonicMind actually, see my other comment below in the comments. I posted an explanation and some code which you can try & play around with.

@@PythonicMind how did you fix it? i remember not being able to get playback speed exactly the same as recording speed

thanks :)

Hey I also want this but till I understand it I will jus use audacity

@@cybeartron ik

👍

actually, he was being striked by youtube, so he uploads them on patreon for his members and not on youtube

@@MananGandhi I am now a patreon :)

@@carlabosse appreciate it brother :)

thanks :)

@@NeuralNine You're da best! Keep it up!

Is it playing every 20 frames at 120 fps..?

Yes this must be it. It's writing 120 frames per second, but 20 fps was specified in the cv2.VideoWriter(). For anyone reading this; if you want regular video speed, set the same as fps on cv2.VideoWriter() as the amount of frames you actually write per second.

It seems i have the same issue of the sped up output video. I'm not sure what causes this as it makes no sense for the waitKey to play a role.

It seems that both pyautogui.screenshot() and out.write(frame) take quite some time to take a screenshot and write it to the output file. This means that you'll always be writing the captured screenshot less often than your specified fps. I'm not quite sure how to solve this, but it seems that this method is not very well suited to record the screen, as it will always end up capturing less frames per second than specified as FPS. For example; on my machine it takes 20 ms to make the screenshot, and another 20 ms to write it to the output file. The whole loop is about 50 ms per iteration. This alone means that it's not possible to capture more than 20 fps with this method, on my machine.

import cv2 import numpy as np import pyautogui import keyboard import time SCREEN_SIZE = (1920, 1080) FPS = 20 fourcc = cv2.VideoWriter_fourcc(*"XVID") out = cv2.VideoWriter("output.avi", fourcc, FPS, (SCREEN_SIZE)) prev = 0 snapshot = False while True: time_elapsed = time.time() - prev print("time elapsed: ", time_elapsed) if not snapshot: print("taking screenshot...") img = pyautogui.screenshot() snapshot = True if time_elapsed > 1.0/FPS: prev = time.time() print("writing frame") frame = np.array(img) frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB) out.write(frame) snapshot = False if keyboard.is_pressed("esc"): break out.release()

kind of 2 years late lol but he uses shotcut

Apparently NO!

"puautogui" should be "pyautogui" you misswriten "u" for " y"

" import cv2 import numpy as np import pyautogui import time SCREEN_SIZE = (1920, 1080) fourcc = cv2.VideoWriter_fourcc(*"XVID") out = cv2.VideoWriter("output.avi", fourcc, 20.0, (SCREEN_SIZE)) fps = 120 prev = 0 print("started") while True: time_elapsed = time.time() - prev img = pyautogui.screenshot() if time_elapsed > 1.0/fps: prev = time.time() frame = np.array(img) frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB) out.write(frame) cv2.waitKey(100) cv2.destroyAllWindows() out.release() " My code any error or mistakes pls tell me

The screen size might be wrong. Make sure it is your display's screen size.

@@ajiteshkumar ok i will do that

Its the number of the frames that should be shown in each second. Fps

this VideeoWriter Error , put this VideoWriter True

Use virtual box 📦

He did say. It's WSL.

Go to Micosoft Store, then search for Ubuntu. Ubuntu subsystem for windows.

also, would it be possible to make this stream aswell? like to twitch or something

@@ninjacodertech It is, but you might want to dive deeper. (You could also just use obs)

is it inputs using the console, or a different file of inputs? Inputs given through console can be gotten by x = input("prompt"), for inputs from a file, it depends on the file and the format.

Try to look at %appdata%\Microsoft\Windows\Start Menu\Programs\Startup Thats a startup folder if something there just delete it (Windows 10)

@Ișfan Matei the program runs, but not the video? All the opencv stuff is new to me, so I'm not the best person to troubleshoot this. Maybe yours ran so quickly it looked like nothing happened. Does your code create a file? Of what size is the file? Is the extension correct? Maybe an issue with your media player playing files of that extension? Just a few initial thoughts.

oh my god how much big screen does your computer have
