Add moviepy 2 compatibility

[Daraan]

Currently moviepy v2+ cannot be used to add videos because the content of moviepy.editor was refactored to moviepy.__init__.py.

This PR now uses just from moviepy import ImageSequenceClip instead of moviepy.editor.ImageSequenceClip.
Furthermore as fallback to moviepy < 2 it will use the direct location from moviepy.video.io.ImageSequenceClip import ImageSequenceClip instead via moviepy.editor which would import more modules and dependencies like requests which are not actually necessary and listed in the current error message.

[Daraan]

On second though using from moviepy.video.io.ImageSequenceClip import ImageSequenceClip without using headfiles might be even better.

For the python 3.11 error, I might have misconfigured the coverage test token. Let me check.

[Daraan]

I've looked at the test and think they do not cover moviepy right?

I've tested v2 vs v1; with the setup test it fails downstream in imageio/plugins/pillow.py when it should write the gif with one color channel

ValueError: Can't write images with one color channel.

Converting this back to a draft and checking what changed

[Daraan]

Thank you for the update.

I think there are about possible ways to get around the problem. There is one thing that confuses me though.
If I run the test with moviepy==1.0.3 imageio==2.27 protobuf==4.22.3 the test fails due to a mismatch with test_summary.test_video.expect.

For moviepy v2 the reason is that the test gif is saved as RGB rather than grayscale making the file bigger, why the 1.0.3 is different from the current version I cannot tell.

@lanpa could you maybe verify if you would generate a different file nowadays as well?

---

I found different way that allows to pass a 2D grayscale tensor in moviepy v2 as well but that solution is more involved

---

Minor note: The last commit theoretically allows to run the make_video code to run on imageio > 2.27 as well.

[Daraan]

I now modified the tests to not depend on the imageio/pillow versions.

In line 393, using the Version function is a good idea. Instead of trying to import a specific package, should we also use it here to explicitily determine the version of moviepy 1 and moviepy 2?

[Daraan]

I've reworked the version parsing to use importlib.metadata instead. Im undecided what to do with the actual import. I would like to avoid using from moviepy.editor import ... as this might fail due to a missing requests module.

We could just use from moviepy.video.io.ImageSequenceClip import ImageSequenceClip as it will not enter the except clause with moviepy v1. Just in the event of another moviepy refactoring that statement will break.

[lanpa]

Can this be imported at the beginning of the file?

[Daraan]

Yes they should be installed with the test requirements. I put it down there as I was not 100% sure if pillow will be installed with the normal setup.

Hi, I have tested the newest commit with moviepy==2.1.2 (with python examples/demo.py). But in the tensorboard webpage, the gif is a static image. If I run with moviepy==1.0.3, it's normal. What should I do? Thanks!

Thank you for checking.
This might be related imageio/imageio#974

Can you tell me you imagio and pillow versions.

[Daraan]

should I move the imports to the top of the file? I am not sure how you like to handle it.
