MediaInfo::EnvironmentError (/usr/local/bin/mediainfo cannot be found. Are you sure mediainfo is installed?)

[rgaufman]

I have mediainfo installed:

$ which mediainfo
/usr/bin/mediainfo
$ /usr/bin/env mediainfo --version
MediaInfo Command line,
MediaInfoLib - v0.7.82

However the gem is looking for it in the wrong place:

irb(main):004:0> media_info = MediaInfo.from('./bad-video-hikvision.mkv')
Traceback (most recent call last):
        5: from /usr/bin/irb:11:in `<main>'
        4: from (irb):4
        3: from /var/lib/gems/2.5.0/gems/mediainfo-1.0.1/lib/mediainfo.rb:86:in `from'

MediaInfo::EnvironmentError (/usr/local/bin/mediainfo cannot be found. Are you sure mediainfo is installed?)

It would be good if it would find it using /usr/bin/env and only fallback to the hardcoded path.

From the README:

You can specify an alternate path for the MediaInfo Binary:
ENV['MEDIAINFO_PATH'] = "/opt/local/bin/mediainfo"

I decided to use /usr/local/bin/mediainfo as it is the default installation directory when you compile MediaInfo. The goal is to support the majority with little configuration, while supplying the ability for the few to configure for specific/custom needs.

With that said, I think /usr/bin/env is a way better idea than using the absolute path. Please make a pull request and I'll be sure to bring it in.

Thanks!

https://stackoverflow.com/questions/2108727/which-in-ruby-checking-if-program-exists-in-path-from-ruby has a discussion on how to search the path. Can we use something from here? Perhaps the ptools gem?

Including this in the next release. Thanks for the great code @tbhi
