Steps to Reproduce the Problem

import moviepy.video.VideoClip

Specifications

• Python Version: 3.7
• Moviepy Version: 0.2.3.5
• Platform Name: macOS
• Platform Version: High Sierra

Cause

Recently imageio just updated to 2.5.0, deprecated imageio.plugins.ffmpeg.get_exe() and changed its behavior.

Now the new get_exe() requires the new package imageio_ffmpeg, but is neither required by moviepy nor imageio (as they are not using that function anymore).

This behavior has caused moviepy to stop working when trying to initialize the config.

Temporary circumvention

1. Set environment variable FFMPEG_BINARY to the absolute path of ffmpeg, or
2. Downgrade imageio to ~2.5.1

[Zulko]

Thanks for this, and sorry I didnt react to the changes in imageio earlier.

Would adding imageio_ffmpeg as a dependency solve the issue?

[blueset]

No worries, imageio just updated a few hours ago, and I got this exception from someone using my library which is depended on moviepy.

That does help to prevent the exception, but including imageio_ffmpeg will download the binary for most common platforms. It might be redundant if ffmpeg is already installed otherwise.

[Zulko]

I understand that this is not ideal but this seems like a reasonable solution for now. It seems that imageio used to download FFMPEG only if needed but that is not the case anymore.

It seems that imageio-ffmpeg is a nice and focused wrapper and moviepy could use much more of its api, but I don't have much time these days.

Would adding imageio_ffmpeg as a dependency solve the issue?

imageio_ffmpeg is only for Python 3.4+ and doesn't work for 2.7

[floAr]

It appears that none of the workaround actually functions for me. I tried the moviepy + imagio 2.4.1 combi as well as the same + imagio_ffmpeg, as well as moviepy + imageio 2.5.0 + imageio_ffmpeg. Running on Windows within conda environment (Everything was installes from conda-forge).
Any tipps on how to proceed?

[Zulko]

I believe I fixed it on Github at least for Python 3 (not sure). Can you try to pip install from this Github repo and let me know if it works?

pip install --upgrade git+git://github.com/Zulko/moviepy

If it does I will push a new version on PyPI asap.

Yes this does the fix. I appreciate the quick response, saved me quite some time tonight

[Zulko]

Awesome. Could you confirm that you can run a minimal example? (this would reassure me that ffmpeg got downloaded properly and is usable by moviepy)

I can't push to Pypi from my current location, but I will, first chance I get.

Looks good thanks!

[das7pad]

ffmpeg is packaged in the wheels of imageio-ffmpeg only. And strangely this combination failed and downloaded the tar ball:
pip==18.1, wheel==0.33.0 (latest), moviepy via git

$ docker run --rm --tty python:3.7 bash -c "pip install 'pip<19' wheel==0.33.0 && pip install git+git://github.com/Zulko/moviepy" | grep imageio-ffmpeg-0.2.0.tar.gz

[das7pad]

Let's lock imageio to a known good state until they fixed their ffmpeg integration.

[Zulko]

@das7pad From what I understand imageio is going to deprecate their old versions, meaning that they may point to deprecated URLs to download ffmpeg (ffmpeg didnt come with a wheel before, it was downloaded with imageio.ffmpeg.download() at runtime at the first use of Moviepy).

[das7pad]

The binaries are still there - they were yanked but then put up again.

[Zulko]

Not sure what to do, let's ask @almarklein: what would you advise regarding @das7pad's last 3 comments (case where imageio-ffmpeg doesnt get installed as a wheel by pip, so ffmpeg doesn't come packaged with it)

[das7pad]

Note: I opened an issue over in their repo: imageio/imageio-ffmpeg#12

[almarklein]

Sorry to put y'all through this. I posted in a new issue #908 that should answer most questions.

Looks like this was all sorted.
