Use librtlsdr to get input directly from a SDR.

This is a feature I'm pursuing. It will not be integrated until v2.0

Just started playing with sdr. I have a macbook Pro installed librtlsdr and can play radio and decode Pagers etc. Installed dsd with no problems and cannot get it to work. I have tried so many different ways to connect rtl_fm to dsd and play but not enough information out there that I can find to make something work. It just quits without any errors. Could you please point me in the right direction. Just need some formulas to work with. Thanks in advance.

If it helps, I use rtl_fm to get P25 data like so:

rtl_fm -f XXXXX -p 49 -s 48000 -g 25 -M fm | dsd -i - -o /dev/null -v99 -g25

Had no luck with dsd 1.6.0 from Homebrew. Compiling version 1.7.0 from source worked right away.
