Question

所有内容似乎都写入了我的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？另外，我对python有相当的经验，但是openCV对我来说是新的。

提前谢谢！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()

无法读取cv2.VideoWriter创建的avi文件
