录制视频，自动保存，然后重新录制

Question

我正在寻找每一分钟保存视频并重新录制的方法。当我运行我的代码时，我会捕获它，直到我按下'q‘。有没有一种方法可以自动保存并重新录制？我用imutils，cv2

import imutils 
import cv2 # opencv 모듈

video = ""

result_path = "result_video.avi"

if video == "":
    print("[webcam start]")
    vs = cv2.VideoCapture(0)

else:
    print("[video start]")
    vs = cv2.VideoCapture(video)

writer = None

while True:
    ret, frame = vs.read()

    if frame is None:
        break

    frame = imutils.resize(frame, width=320, height=240)

    cv2.imshow("frame", frame)

    key = cv2.waitKey(1) & 0xFF
    if key == ord("q"):
        break
                                    
    if writer is None:
        fourcc = cv2.VideoWriter_fourcc(*"MJPG")
        writer = cv2.VideoWriter(result_path, fourcc, 25, (frame.shape[1], frame.shape[0]), True)

    if writer is not None:
        writer.write(frame)

vs.release()
cv2.destroyAllWindows()

你还没有发布你的代码，也不是很明显，你是如何记录的，但是下面的代码可以为你添加一个计时器，它提供了大量的定制，例如在指定的秒、分钟甚至几个小时内记录一次。

from time import sleep
from apscheduler.schedulers.blocking import BlockingScheduler

def RecordVideo():
    print("Starting the recording")
    #record your content
    #close camera/desktop or other resource
    print('Recording Completed!')
    

scheduler = BlockingScheduler()
scheduler.add_job(RecordVideo, 'interval', minutes=1) #once per minute
#scheduler.add_job(RecordVideo, 'interval', seconds=60) for timer in seconds
#scheduler.add_job(RecordVideo, 'interval', seconds=60) for timer in hours
scheduler.start()

while True: #keeps the program running
    sleep(0.1)

只需将录制功能添加为作业即可
