How can I tell if I am a corner case or v4lctl is just broken? xawtv depends on the driver. Older versions of the xfree86 v4l module used to provide a XV_VOLUME control unconditionally for example. It might be also a misconfigured "mixer = foobar" line in $HOME/.xawtv (but in this case mute/unmute is broken too). > $ xawtv -hwscan > port 46-46 [ -xvport 46 ] > /dev/v4l/video0: OK [ -device /dev/v4l/video0 ] > Any ideas why the extra knobs are not coming up? xawtv uses the first one by default, i.e. the xvideo device. You don't get the v4l2 controls then. Try the "-noxv" or "-device /dev/v4l/video0" switch ... Gerd -- #define ENOCLUE 125 /* userland programmer induced race condition */
