update ffmpeg on QNAP

[lyapounov]

Just for clarification,

I have downloaded ffmpeg from http://johnvansickle.com/ffmpeg/ to get the Soxr library, and installed it on my Synology (Intel one, DS415play)
I have added /volume1/MinimServer/opt/bin/ffmpeg to stream.converter value, and convOut=-af aresample=resampler=soxr:precision=28 to stream.options

now : if I read the user's guide :

flac:wav24 does not use ffmpeg
but flac:wav24; does, because of the ;

is this correct ?
