[CentOS] libv4l question

Hi all,

Hey I'm trying to do some web cam stuff, and I found this link:
http://freshmeat.net/projects/libv4l/releases/333037

I was doing the "rpm -qa | grep v4l" and nothing comes up,
I did "ls path_to_centos/RPMS/* | grep v4l " and nothing comes up,
I did 'yum provides "*/libv4l*"' and nothing comes up.

Is the CentOS library for v4l named something different?
Is this library something I can just grab and compile and "help" with my 
v4l efforts?
Do I not need this library at all?
I'm using 5.6 x86_64.

Just a little confused at the moment.

Thanks,

Jerry
