Hello! I'm somewhat confused about the ioctl()s after reading linux/Doc*/vid*/API.html. Via VIDIOCSAUDIO i can force my radio driver to mono sound. But what should I report on VIDIOCGAUDIO (mode=V_S_STEREO/V_S_MONO) and VIDIOCGTUNER (flags=V_T_STEREO_ON)? a) what the user forced before (mono) b) what the tuner is capable of (stereo) c) what the current broadcaststation is sending (cant check this when tuner is forced to mono...) If I should answer with b) on VIDIOCGAUDIO (s/m both) and with a) on VIDIOCGTUNER, then are the application sane enought to force stereo after open()!? - Should the driver change it back on open()?? Who can help? It's slightly suboptimal here... [: Ciao, Rob PS: There _is_ information about obtaining RDS raw-data from a RDS tuner in API.html... (:
