python - 无法读取 cv2.VideoWriter 创建的 avi 文件

Question

一切似乎都写入了我的 avi 文件 output.avi（它比我启动程序之前大）但由于错误 0xc10100be 我无法打开它。我将如何尝试使文件可读？我对 python 也很有经验，但 openCV 对我来说是新的。

提前致谢！代码：

import psutil
import time
import cv2
import wx
import pyautogui
import numpy as np
import subprocess as sp

running = True
while True:
    if "League of Legends (TM) Client" in (p.name() for p in psutil.process_iter()):
        app = wx.App(False)
        SCREEN_SIZE = wx.GetDisplaySize()
        SCREEN_SIZE = tuple(SCREEN_SIZE)
        fourcc = cv2.VideoWriter_fourcc('M', 'J', 'P', 'G')
        out = cv2.VideoWriter("output.avi", fourcc, 20.0, SCREEN_SIZE)
        ffmpeg = 'FFMPEG'
        dimension = '{}x{}'.format(SCREEN_SIZE[0], SCREEN_SIZE[1])
        f_format = 'bgr24'
        fps = str(out.get(cv2.CAP_PROP_FPS))

        command = [ffmpeg,
                    '-y',
                   '-f', 'rawvideo',
                   '-vcodec', 'rawvideo',
                   '-s', dimension,
                   '-pix_fmt', 'bgr24',
                   '-r', fps,
                   '-i', '-',
                    '-an',
                   '-vcodec', 'mpeg4',
                   '-b:v', '5000k',
                   "output.avi"]
        proc = sp.Popen(command, stdin=sp.PIPE, stderr=sp.PIPE)
        while True:
            img = pyautogui.screenshot()
            frame = np.array(img)
            frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
            out.write(frame)
    time.sleep(5)

cv2.destroyAllWindows
out.release()
