If you download a "source" package (usually called [something].tar.gz) you will have to read the "README" and "INSTALL" files. the "INSTALL" file usually says "These are generic instructions" at the top, if it does say that then you can bet it will tell you to do this:
1. Extract the archive:
cd /path/to/[something].tar.gz
gunzip -v [something].tar.gz
cd ./[something]
./configure
make
su
[password]
make install
Read any errors that may occur carefully, errors usually mean something else (a "dependancy") is required on your system.
If all goes well then your software is correctly installed.
As for video capture software, you will have to search the forums. Your camera should, when plugged in, have created a node in /dev folder; usually something like /dev/video0 or /dev/input/video0, any piece of software can now access your camera.
I use
mplayer
Here is my code for using mplayer to display the output of my camera:
Code:
mplayer -tv driver=v4l:device=/dev/video1:width=352:height=288 -vf pp=li tv://
To capture the stream:
Code:
mencoder -tv driver=v4l:device=/dev/video1:width=352:height=288 -vf pp=li -oac=lavc -ovc=lavc -o ~/capture.avi tv://
(mencoder is part of mplayer)
