Hi,
There seems to be a need for a web cam streamer for FreeBSD so I have
figured out a VERY tempary solution.
I just created a web cam "steam" (just a page auto-refresh every 60
seconds).
The webcam:
Logitech Quickcam Express
http://www.logitech.com/index.cfm/products/details/GB/EN,CRID=2204,CONTENTID=5037
The software:
qcamview (you can view a REAL stream with this, but we need
qcamshot that comes with it)
WebMagick (we only need the convert utility that comes with this)
What I did and why I did it?
I wanted a webcam stream for my friends/family in Australia, South
Africa and the UK.
Added a user called cam to the wheel group.
added some lines to /etc/devfs.conf:
#Webcam
own /dev/ugen0 root:wheel
perm /dev/ugen0 0644
own /dev/ugen0.1 root:wheel
perm /dev/ugen0.1 0644
own /dev/ugen0.2 root:wheel
perm /dev/ugen0.2 0644
made a simple script named webcam.sh in my home dir, it looks like this:
#!/usr/local/bin/bash
qcamshot > ./~/public_html/image.ppm
convert -despeckle ./~public_html/image.ppm ./~public_html/image.jpg
chmod 755 ./~/public_html/image.jpg
Now I added a line to my /etc/crontab:
#Run the script every minute.
*/1 * * * * cam /home/cam/./webcam.sh
Then created a html file with the refresh tag set to 60, kinda looks like:
<meta http-equiv="refresh"
content="60;http://www.mydomain.com/path_to_autorefresh_page">
Sorry if this does not relate to what anyone really needs, but it is
02:39am and im tired :-) and thought
at least 1 other person might need this, you can alter the crontab to
take images more frequently and
set the refresh accordingly.
For a FreeBSD NON-guru i feel pretty good that I managed this. wo0t!
Hope someone finds this useful.
Cheers,
Jay... a very sleepy one...
