将 Cv2 视频文件保存到另一个位置

Question

我有一个使用 python 在后台录制网络摄像头的脚本，但我想将剪辑保存到特定目录，我想知道是否有任何方法可以做到这一点

import cv2

cam = cv2.VideoCapture(0) # Começa a gravar
out = cv2.VideoWriter('Teste.avi', -1, 20.0, (640, 480))

   

if cam.isOpened(): # Camera on ou não
    op, frame = cam.read()
else:
    op = False


while op:

    if cv2.waitKey(1) == ord('x'): # Para o programa
        break

cam.release()

Answer 1

import cv2

cam = cv2.VideoCapture(0) # Começa a gravar
# out = cv2.VideoWriter('Teste.avi', -1, 20.0, (640, 480))
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('path//of//location//output.avi',fourcc, 20.0, (640,480))

while (cam.isOpened()):
    op,frame = cam.read()
    if (op == True):
        out.write(frame)
        cv2.imshow('frame',frame)
        if cv2.waitKey(1) & 0xFF == ord('x'):
            break

    else:
        break

cam.release()
out.release()
cv2.destroyAllWindows()

如果有疑问，可以参考文档。

Answer 2

import os
your_path = "location where you want to save"
try:
    os.mkdir(your_path)
except:
    pass #directory already there
out = cv2.VideoWriter(your_path+'/output.avi',fourcc, 20.0, (640,480))
