Empty error detail

When there is a conversion error the error string is not shown in the interface. The error is shown by running the same command from terminal, so it's not a ffmpeg problem.

Try ffmpeg static build from here:

Meanwhile I wrote a patch that prevents starting the conversion if the codec is missing, I think it is clear to the user
#27

Yeh, this an issue, sometimes Curlew does not show the details of errors.

because libvo_aacenc has been removed from ffmpeg. It was a crappy encoder anyway. Use libfdk-aac, that one's the best.

see #46
