VideoFileClip error about moviepy

[Zulko]

Thanks for the feedback. It's a strange error, like if FFMPEG couldn't read the first frame of the file. One possible reason would be that you don't have a recent version of ffmpeg (if you are on ubuntu/debian, the version in the repos is deprecated, you need to download a recent version on the website).

If it's not that, could you provide a file for which it doesn't work ?

[Zulko]

Huh, fixed ?

That has got to be the fastest fix ever. It was what you said.

[Zulko]

Yeah ! I will see what I can do to improve the error messages. This one really sucks.

Hi,
I realise this is closed - however I get the same error on Ubuntu 14.04 - I think it's because Ubuntu uses libav, which being a fork is slightly incompatible with ffmpeg.

These two are probably going to remain forks for a couple of years, is it possible to support libavs ffmpeg library ?

Hi,
I didn't understand, did you install the last version of ffmpeg ? It is straightforward, you just download the binary on the website and copy it in usr/bin.

Ah in the end I tried this. Just with the default ffmpeg it doesn't work, was wondering if it's possible for it to work with the default setup.

Just to be sure, it worked when you updated ffmpeg, right ?

I don't think it is a good idea to try and make it work with avconv. I spent a lot of time understanding the subtleties of ffmpeg (it's trickier than it seems) and I really don't want to spend more time doing support for avconv. I believe that using one single software like ffmpeg (i chose ffmpeg over avconv because it is more common on all platforms) makes the code more coherent, I would have to code alternative commands for almost all the i/o functions if we were to make moviepy avconv-compatible.

The current situation is only damaging for Ubuntu/Debian users (I am on Ubuntu, btw), but that is because the packagers have decided to completely deprecate ffmpeg, even in the repos, which is completely nuts imho.

It did work with ffmpeg in the end.

Given enough time the forks will reconcile I guess.
