Warnings are suppressed by moviepy

[fepegar]

Hi,

Thanks for the library, I think it's great.

My warnings are being suppressed/captured after I import certain moviepy modules. I suspect it's caused by this line:

moviepy/moviepy/video/io/ffmpeg_reader.py

Line 19 in 4d70eab

logging.captureWarnings(True)

Steps to Reproduce the Problem

iPython 3.8.2 (default, May  6 2020, 02:49:43)
Type 'copyright', 'credits' or 'license' for more information
IPython 7.13.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import warnings

  warnings.warn('x')

In [4]: from moviepy.video.io.VideoFileClip import VideoFileClip

In [5]: warnings.warn('x')

Hey, thanks for the report. That is definitely not ideal, and should be looked at before the release of v2.0.

In the meantime, it looks like if you call logging.captureWarnings(False) after importing moviepy, then it should go back to the default behaviour.
