It works fine on my computer. It's not a filename problem (because that gives a different error) so I'd say it has to do with corrupted files (like, an embryo of a file or something). Can you give more infos ? Like the script that produces the issue (how is the file downloaded ?), a video for which it works and one for which it doesn't. Also what OS are you on, and do you use a recent version of MoviePy ?

Now that u mention it, the video is downloaded by youtube-dl with format
set to flv. Thinking that file format might be the problem for moviepy. Do
you have any parameters you use to download that video from youtube via
youtube-dl?

I came, I saw, I wondered.

Yes I think you can choose the format with youtube-dl (by default it gives you the highest quality it can find). But I don't know how.

I don't think it is the issue. I downloaded the flv using DownloadHelper (because youtube-dl gave me an mp4 by default). It works fine with the flv too. Unless the two flvs (mine and yours) have different internal formats

... But again: 'no attribute 'reader'" is not a real bug, it is a side-bug trigerred when quitting MoviePy after another bug occured. So I'd really need to see the complete error returned by moviepy.

@Zulko problem solved...it was silly but somehow subprocess.call() wasn't blocking the execution of youtube-dl command, so moviepy ended up reading the file before it was downloaded, which caused the issue.
