# Install xawtv (xawtv-3.95-7.fc8)
> yum install xawtv
# Install mencoder (mencoder-1.0-0.90.rc2.lvn8 from the livna repository)
> yum install mencoder
The xawtv package contains tools which allow you to connect to the webcam, grab pictures and videos on the fly and also produce movies from the snaps.
# Check that the webcam is recognized and broadcasting:
> xawtv -c /dev/video0 &
/dev/video0 : the device (use xawtv -hwscan to see which one it is for you)
# You can grab pictures in two ways with xawtv: using webcam or using streamer.
# grab snapshots using streamer
> streamer -c /dev/video0 -j 85 -t 1200 -r 0.03 -o office-0000.jpeg
/dev/video0 : the device
85 : JPEG quality
1200 : number of snapshots to grab
0.03 : frames per second (here it's about 1 snap every 30 seconds)
office-0000.jpeg : output file with counter to accomodate 4 digits here
# grap snapshots using webcam
