video_dir in "default.cfg" does not do anything

[kolibril13]

The "default.cfg" file looks really nice!
Thanks a lot for making this, it has really great potential.

When testing it, I run into an issue:

In the old manim version, I ran my programms with manim -l -p --video_dir ~/Downloads/ HelloWorld.py
But now, I want to define the video_dir in "default.cfg".

Here, I found in line 70-71:

# # --video_dir
# video_dir = %(MEDIA_DIR)s/videos

and changed it to:

# # --video_dir
video_dir = ~/Downloads/

But the video output dir is unchanged, here the output of the script:

Thanks @kolibril13. You can see in https://github.com/ManimCommunity/manim/blob/master/manim/config.py#L117 that the vide_dir, tex_dir, and text_dir are now always subdirectories of media_dir. This is in accordance with #66. The --media_dir flag is still available to you to change the output directories.

This is related to #132

@kolibril13 I'm closing this for now as wontfix because this is intentional. Following my latest comments on #132, if you wish to change this behavior, please let's make a separate issue to implement such a change. Thanks :)
