On Ubuntu/Debian for instance the version in the repos is deprecated. Please update to a recent version from the website.

Sorry, I cannot replicate this with the file that you sent me in #1233. Are you using the code in #1222?

As with all bug reports, please provide the exact code that you are running and the media file that you are using it on (or use one of examples from moviepy/media).

Hi, this issue still exists on latest version of moviepy. Here is what I tried to reproduce:

ffmpeg_reader.py shows the warning which is mentioned in issue title. Is it safe to ignore?

tburrows13 commented 3 years ago

Yes you can ignore that warning. It just means that moviepy was expecting one extra frame at the end of the video that wasn't there, so it duplicated the last frame instead. There's been quite a few changes in this bit of moviepy's code since 1.0.3 so it might be fixed in 2.0 anyway.

cgnerds commented 2 years ago

Your video file may be corrupted, you can check it with ffmpeg.
