I'm beginning to think this was not meant to be. I finally got bttv installed correctly and now when I run it I get this:

[me@here user]# bttvgrab
bttvgrab error: Is a directory (open /dev/video)

open /dev/video?

I don't know about that bttvgrab, it's been abandoned for nearly a year...

Just an idea, but try:
mplayer -tv off:driver=v4l:width=320:height=240 -jpeg progressive:outdir=/var/www/html/grabs -vo jpeg

If you prefer png:
mplayer -tv off:driver=v4l:width=320:height=240 -z 4 -vo png

Not sure about either, but less sure about the PNG option than the jpeg option :)

Cool

I tried the mplayer command you suggested and it says:

Error: option 'tv' has no suboption 'off'

Okay when I do this:

mplayer -tv on:driver=v4l:width=320:height=240 -jpeg progressive:outdir=/var/www/html -vo jpeg

It saves about 10 images per second and it just names them all something different. I get:

00000001.jpg
00000002.jpg
00000003.jpg
00000004.jpg
etc.

So how could I get it to take snapshots at a different time interval and keep saving the images under one name like snapshot.jpg ?

mplayer -tv on:driver=v4l:width=320:height=240 -jpeg progressive:outdir=/var/www/html -sstep 1 -vo jpeg

Note the -sstep 1 option. The 1 means take a picture every second. So if you wanted to change that to "2" or something, that'd be fine.

As for saving them under 1 filename... I'll look into that

Cool
