发生异常: OSError MoviePy错误:读取第一帧视频文件*失败。这可能意味着文件已损坏。
提问于 2022-06-04 22:09:36
我在做什么：
在一定时间内循环播放视频。
但是，我得到了以下错误(该文件没有损坏)：
Exception has occurred: OSError
MoviePy error: failed to read the first frame of video file Pexels Videos 1292738.mp4. That might mean that the file is corrupted.在我的代码中的注释行：
chdir(r'C:\Users\jack_l\Downloads\makeAVideo\stock')
myStock = next(walk(r'C:\Users\jack_l\Downloads\makeAVideo\stock'), (None, None, []))[2]
stockFile = VideoFileClip(str(myStock[0]), target_resolution=(1080, 1920), audio=False)
stockFile = stockFile.loop(duration = 300)
stockFile = stockFile.set_fps(30)
chdir(r'C:\Users\jack_l\Downloads\makeAVideo')
stockFile.write_videofile('theVideo.mp4') # this line有人知道出了什么问题吗？任何帮助都是非常感谢的，谢谢。
我正在使用的文件：

OSError: MoviePy error: failed to read the first frame of video file Pexels Videos 1292738.mp4. That might mean that the file is corrupted. That may also mean that you are using a deprecated version of FFMPEG. On Ubuntu/Debian for instance
the version in the repos is deprecated. Please update to a recent version from the website.回答 1

在write_videofile之前更改文件夹--这可能会造成问题。
代码可以是“懒惰”的，当您定义VideoFileClip()时，它可能不会读取文件，但是当您想在更改目录后编写新文件时，它可能会尝试从新位置读取文件。
您应该使用/full/path/to/Pexels Videos 1292738.mp4而不是chdir()
完整的工作代码：
import os
from moviepy.editor import *
# --- info ---
import moviepy
print('moviepy:', moviepy.__version__)
print('ffmpeg :', moviepy.config.FFMPEG_BINARY)
# --- main ---
input_dir = r'C:\Users\jack_l\Downloads\makeAVideo\stock'
output_dir = r'C:\Users\jack_l\Downloads\makeAVideo'
#print('chdir:', input_dir)
#os.chdir(input_dir)
root, dirs, files = next(os.walk(input_dir), (None, None, []))
#print(files)
if files:
#input_path = os.path.join(root, files[0])
input_path = os.path.join(input_dir, files[0])
output_path = os.path.join(output_dir, 'theVideo.mp4')
print('input :', input_path)
print('output:', output_path)
stock_file = VideoFileClip(input_path, target_resolution=(1080, 1920), audio=False)
stock_file = stock_file.loop(duration=300)
stock_file = stock_file.set_fps(30)
#print('chdir:', output_dir)
#os.chdir(output_dir)
