Support for FreeBSD OS ? about imageio

[almarklein]

We should at least allow using ffmpeg using the system executable.

Actually, when the platform is not supported, imageio will fallback to the system ffmpeg executable. Isn't that enough? Alternatively, we should wrap up that PR of yours that allows setting the ffmpeg executable.

[almarklein]

If just ffmpeg does not work, the user can now do `os.environ['IMAGEIO_FFMPEG_EXE'] = '/path/to/my/ffmpeg'.

Very cool, thanks.

I'm using PC-BSD and decided to give this a try.

It still fails on the init of imagio since it is directly referencing a dictionary from get_platform().

I haven't yet gotten my BSD machine up to being a dev environment yet but I can take a look at it in a few days. (Once I re-install FreeBSD11-CURRENT)

@jedediahfrey Thanks for testing! I'll make some changes to deal more flexible with "exotic" platforms :)

[almarklein]

Fixed it. Could you please try the latest master?

[almarklein]

I am assuming that this works. Please reopen if this is not the case.
