All of the nvrec programs use the config
file /etc/nvrec.conf
here is mine:
# nvrec config file.
# Format: whitespace (including space, newline, tab) separated options,
# as they would appear on the command line.
# Blank lines, and everything after a # and before a newline are ignored.
#-vb 600 # DIVX4 bitrate = 600kbit/s
-vb 1800 # ffmpeg default is already 1800
-va 256 # set audio bitrate high, this shouldn't hurt
-deint bilin
#-h 240 # heigth is set to 288
#-w 352 # with is set to 384
-h 480 # heigth is set to 288
-w 704 # with is set to 384
-v /dev/video0
-norm NTSC
-input Television
-s #stereo
##-r 48000 ( default is OK)
-N 32 ## input buffers
##-vl 4 ## luma factor
-S 0.5 ## sync rate
-vg 300 ## keyframerate
# If you have an SB card, with the sound comming in on "line", you may want
# to uncomment the following.
-mixsrc /dev/mixer:line
-mixvol /dev/mixer:line:100
# If you are using a VIA M/B, and the alsa driver, try this:
# -mixsrc /dev/mixer:line
-mixvol /dev/mixer:igain:50
