#285

Does this account for the change in format mentioned in #285 ?

If not, maybe it'd be easier to get the json formatted output from ffprobe/avprobe?

@jiaaro This is a bug fix from: https://github.com/jiaaro/pydub/blob/master/pydub/utils.py#L284, (because it's not else, for this reason sample_fmt may not exist),

Unfortunately not so well while I understand as utils.py works c ffprobe/avprobe, for this reason did not want to climb there.

Sorry, but the text was translated from the Russian language, so I attach the original:

Это исправления ошибки со строки: https://github.com/jiaaro/pydub/blob/master/pydub/utils.py#L284, (потому как не else, по этой причине sample_fmt может не существовать )
К сожалению пока еще не очень хорошо пока понимаю как utils.py работает c ffprobe/avprobe, по этой причине не хотел туда лезть.
