Got a logitech webcam c300, it uses the "uvcvideo" kernel module.

Typically you would  grab video using "motion" and stream it on mpeg, well that's rubbish if you want better compression, so let's do it using the best of the best: h264.

 #!/bin/ksh

DEV=/dev/logitechcam
ps -ef | grep -i vlc | grep -v grep |grep -i logitechcam | awk '{ print $2 }'| while read P;do
kill -9 $P
done

VLC="/usr/local/bin/cvlc v4l2://$DEV :input=2 :input-slave=alsa://hw:2,0  --alsa-samplerate=32000 --v4l2-controls-reset --v4l2-auto-white-balance=1 --v4l2-do-white-balance=1 --v4l2-autogain=1 --sout "

CAM="transcode{vcodec=h264,acodec=mp4a,width=320,height=240,vb=64,ab=24,channels=1,venc=x264}:standard{access=http,dst=0.0.0.0:8090/stream.flv}"

#CAM="transcode{vcodec=mjpg,width=320,height=240}:duplicate{dst=std{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a}.mux=mpjpeg,dst=0.0.0.0:8090/m.mjpg}}"

${VLC} "#$CAM"

this produces a very decent quality stream at around 100kbps, audio also included!

Enjoy!

You want to know if one of your nics is in the vlan you need it to be? Quite tedious if you want to do it manually.

check this small script to config the ip, ping and unconfig

for i in 1 2 3 4 5 6 7 8 9 10 11;do set -x;ifconfig eth$i inet 10.203.102.102 netmask 255.255.254.0 up; ping -c 5 10.203.102.1; ifconfig eth$i down; done

for eaach disk to include in a volume group, initialize it as a LVM disk:

pvcreate /dev/sdX

create a volume group with that disk:

vgcreate myvg  /dev/sdX

Create a 20gb volume called "myvol" inside the "myvg" volume group:

lvcreate -L 20g -n myvol myvg

Make a filesystem in the new volume:

mkfs.ext3 /dev/mapper/myvg-myvol
