如何使用 OpenCV VideoWriter 将视频保存到特定目录——python

Question

我正在尝试将视频保存在特定文件夹中。但是在运行代码后没有保存输出。有人可以帮忙吗？谢谢。

cap = cv2.VideoCapture(file_paths[0])
fgbg = cv2.bgsegm.createBackgroundSubtractorMOG()
fourcc = cv2.VideoWriter_fourcc(*'XVID')
name = "C:\jupyter_projects\Test Folder\Intention dataset\background_subtracted\out.mp4"
out = cv2.VideoWriter(name,fourcc, 20,(320,180),False)

while(1):
    ret, frame = cap.read()
    if (ret == True):
        resized_frame = cv2.resize(frame,(320,180),fx=0,fy=0, interpolation = cv2.INTER_CUBIC)
        fgmask = fgbg.apply(resized_frame)
        cv2.imshow('Frame',fgmask)
        out.write(fgmask)
        if cv2.waitKey(30) & 0xFF == ord('q'):
            break
    else:
        break
cap.release()
out.release()
cv2.waitKey(5)
cv2.destroyAllWindows()

PS：当我使用默认目录保存视频时，输出将被保存。

out = cv2.VideoWriter("out.mp4",fourcc, 20,(320,180),False)

Answer 1

当你调用该函数时

cv2.VideoWriter("/your/path/filename.mp4",fourcc, 20,(320,180))

我希望它有帮助:)
