fantastic work!
is the fm demodulator supposed to work automagically?
i don't seem to discover anything with this command:
ffplay -sdr_freq 105.5M -station_freq 107.5M -f sdr foo
also tried fiddling with -rtlsdr_fixes
whereas i do get signal with:
rtl_fm -f 107.5M -M wbfm

testing this patch against master i bump into the problem of avpriv_kbd_window_init being undefined.
also if i naively replace it with ff_kbd_window_init, observe FF_KBD_WINDOW_MAX assert in kbd_window_init.
cheers,
