MinimStreamer: incorrect FFmpeg version

[Minimi]

Hi all and hi developer(s) :-)
I tried your MinimServer the last weeks and it worked nicely.

But now its not working anymore.

I've read this Thread: https://forum.minimserver.com/showthread.php?tid=1192
But that did'nt helped.
I have restarted, updated the minimserver/-streamer software as told, but the failure resists. unfortunately.

I'm on a Synology DS1813+ with DSM 5.0-4493 Update 2

Those are my Versions:
   
   

I need to confess, that I have installed a different ffmpeg with ipkg, because the synology ffmpeg did not meet the desired requirements I need to work with ffmpeg. interestingly, there is NO version number showing up, but ffmpeg works here as expected (and needed).

Code:

> ffmpeg --help

ffmpeg: missing argument for option '--help'

So I'd like to ask, if someone could tell me some other hints to get this little piece of software running again?
I would be very very happy again ;-)

Thanks and have a good time, you all!
Cheers,
