I am using a logitech headset on Debian Etch. As such, I dont have a /dev/dsp, which mencoder defaults to for sound capture. Im trying to use this command to capture from my vcr (attached to my rig with a Pinnacle DVC90):
mencoder tv:// -v -tv driver=v4l2:device=/dev/video0:input=0:fps=24:norm=ntsc:amode=1:width=704:height=576 -of avi -sws 9 -vf lavcdeint,denoise3d=4:3:6,scale=512:384 -ovc xvid -xvidencopts bitrate=900 -o ./test.avi
but I segfault with this output:

How can I find the right adevice to give mencoder so i can capture sound with my video?
