[FFmpeg-user] newbie question

[Russell Layberry]

I'm running a webcam from ffmpeg using

ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg

which works fine.  That is the only relevant example from the man page. 
  What would I run if I want to save lossless video only?

Thanks

Russ
