Deprecation warnings

[tburrows13]

When running the test suite it reveals some deprecations:

  /home/runner/work/moviepy/moviepy/moviepy/audio/AudioClip.py:121: FutureWarning: arrays to stack must be passed as a "sequence" type such as list or tuple. Support for non-sequence iterables such as generators is deprecated as of NumPy 1.16 and will raise an error in the future.

  /home/runner/work/moviepy/moviepy/moviepy/video/io/gif_writers.py:323: DeprecationWarning: tostring() is deprecated. Use tobytes() instead.

Source: https://github.com/Zulko/moviepy/runs/1227641497 (under PyTest)
I think that the first one is NumPy and the second is Pillow (PIL).

It would be good to investigate and fix these 2 warnings.

Could you please assign this to me ?

@tburrows13 I do have an "arrays to stack must be passed as 'sequence' type" error which I did not have before, with moviepy 1.0.3, when muxing audio and video (saving the video); isn't this merged? Now it's no longer a warning and the code fails.

facing this issue while converting while running the to_soundarray() method
TypeError: arrays to stack must be passed as a "sequence" type such as list or tuple.

[vinitnalhe]

I was also facing the same issue, when using python3.11.

I tried using the earlier version of python ( python 3.8) and to_soundarray() ran successfully.

[tbrouns]

For anyone stumbling on this like I did:

Installing moviepy from source ( 2.0.0.dev0 ) fixed this issue for me:

pip install git+https://github.com/Zulko/moviepy.git@bc8d1a831d2d1f61abfdf1779e8df95d523947a5

More info

The PR attached to this issue solved the problem: #1443

Sample code that is working now, but didn't work with moviepy==1.0.3:

load_path = "path/to/my/video.mp4"
video = VideoFileClip(load_path)
audio_data = video.audio.to_soundarray(fps=16000)

[agamm]

pip install git+https://github.com/Zulko/moviepy.git@bc8d1a831d2d1f61abfdf1779e8df95d523947a5

Why is this not added to a release yet?

pip install git+https://github.com/Zulko/moviepy.git@bc8d1a831d2d1f61abfdf1779e8df95d523947a5

Why is this not added to a release yet?

Because The Zulko is Not Active and #2085.
