电影问题："utf-8"编解码器无法解码位置 1494 中的字节0xb5：无效的起始字节

Question

我得到了"'utf-8’编解码器无法解码位置1494中的字节0xb5：无效的起始字节"；当我尝试访问本地视频文件时。我把文件上传到谷歌硬盘，并在colab中运行代码，一切都很好。当我用jupyter笔记本在本地驱动器上运行它时，我遇到了这个问题。

我的代码：

import moviepy.editor as mp    
path='D:/Movie/Multimedia_Corpus/Test01/video_files/'
file='test01.rmvb'
fclip=mp.VideoFileClip(path+file)

错误：

Answer 1

试试这个：

infos = error.decode("utf-8", errors="ignore")

或者你可以安装moviepy==2.0.0.dev2，它就会工作。

注意：moviepy的2.0.0.dev2版本尚未发布。

Answer 2

我发现这实际上是moviepy的一个bug。我打开ffmpeg_reader.py并更改了第259行，即问题中发布的第三行错误。

原始代码：

infos = error.decode('utf8')

新代码：

try:
infos = error.decode('utf8')
except:
infos = error.decode('ANSI')
