屏幕记录低fps的输出？

发布于 2025-02-06 14:30:14 字数 697 浏览 2 评论 0原文

我有这个屏幕录音机，但是输出我注意到较低的fps，例如大量帧掉落，如何解决？我的显示器甚至有120 Hz，因此Vero平滑，但是在输出中，如果我将fps电价从6增加到20，例如，视频速度速度太快，那么如何解决？谢谢

import datetime
from PIL import ImageGrab
import numpy as np
import cv2
time_stamp = datetime.datetime.now().strftime("%Y-%m-%d %H-%M-%S")
file_name = f"{time_stamp}.mp4"
fourcc = cv2.VideoWriter_fourcc("m","p","4","v")
captured_video = cv2.VideoWriter(file_name,fourcc,6.0,(1920,1080))
while True:
    img = ImageGrab.grab(bbox=(0,0,1920,1080))
    img_np = np.array(img)
    img_final = cv2.cvtColor(img_np,cv2.COLOR_BGR2RGB)
    cv2.imshow ("Secret Capture",img_final)
    captured_video.write(img_final)
    if cv2.waitKey(50) == ord("q"):
        break

I have this screen recorder but the output i notice low fps, like a lot of frame drops, how to solve? My monitor has even 120 hz so it's vero smooth, but in the output is like 60 hz not very smooth, if i increase the fps valure from 6 to 20 for example the video is too fast like x2 in speed, so how to solve? Thanks
