setuptools as an install dependency?

Spotted you're having setuptools as an install dependency, which looks wrong to me, as the install dependency is read by setuptools itself, so if this value is read, setuptools is already here.

And the other way around if setuptools is not here there's no way to discover this install_dependency (as it's given as a paramter of setuptools.setup).

Not pinning it won't hurt a lot though, but it can still bite: if a project requiring pymediainfo is freezing subdependencies, it will pin setuptools on a specific version, which could conflict with pip itself.

I found out by running pip-compile on a project of mine which depends on pymediainfo (Thanks! I appreciate the project!), thanksfully pip-compile don't pin the version in this case, to avoid conflict with pip:

$ echo pymediainfo > foo.in
$ pip-compile foo.in
$ cat foo.txt
#
# This file is autogenerated by pip-compile
# To update, run:
#
#    pip-compile foo.in
#
pymediainfo==4.2.1        # via -r foo.in

# The following packages are considered to be unsafe in a requirements file:
# setuptools

I'd recomand removing it.

Setuptools is needed here:

pymediainfo/pymediainfo/__init__.py

Line 9 in 7eccc4b

from pkg_resources import get_distribution, DistributionNotFound

I feel not listing it would be wrong.

Oh, pkg_resource, good old Kryptonite...

It looks completly legitimate, I missed it. And as pip-compile don't pin it, it won't conflict with pip in my setup, so I close this issue.
