A bunch of error messages containing ffmpeg

It is highly likely that the video name or path contains spaces, special characters, Chinese, Japanese, Korean, or Arabic characters, causing the execution of ffmpeg to fail.

Rename the video to a simple name consisting of "English letters and numbers", and move the video to a directory consisting of simple characters such as "English letters, numbers, and underscores". This applies to the parent and grandparent directories as well.

For example, C:/Program file/videos is not acceptable because it contains spaces.

D:/videos[001] is not acceptable because it contains special characters [].

E:/中文 ceshi 개하였다 contains Chinese, Korean characters and spaces, and will result in an error.

E:/myvideos001 is acceptable because it contains no spaces or special characters.
