there is no official release files for uvcvideo, i only find it via svn, so based on this instructions u need to enter this command to install it.

1. open terminal (lets say you already have a folder name linuxzip in ~/linuxzip)

[planet@fedorasal linuxzip]$ svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
A trunk/uvc_ctrl.c
A trunk/uvc_queue.c
A trunk/uvc_video.c
A trunk/uvc_v4l2.c
A trunk/uvc_compat.h
A trunk/uvc_driver.c
A trunk/uvcvideo.h
A trunk/Makefile
Checked out revision 125.
[planet@fedorasal linuxzip]$

2. then
[planet@fedorasal linuxzip]$ cd trunk/
3. type make and lastly make install (as root)

[planet@fedorasal trunk]$ make

one of the commenter john perez asked me about sound system in fedora 7, actually i have same problem like him, i can't have sound in mplayer when i view youtube video, but if i closed youtube website, i can play mplayer, the problem is i can't have multiple sound like before, i have to turn off another application that use sound system, anyway i found the solution to fixed this bug, from here..
linuxquestions.org - multi application sound
1.just copy this code to /etc/asound.conf (as root)

pcm.!default {
    type plug
    slave.pcm "swmixer"
}

pcm.swmixer {
    type dmix
    ipc_key 1234
    slave {
            pcm "hw:0,0"
            period_time 0
            period_size 1024
            buffer_size 4096
            rate 44100
    }
}
ctl.swmixer {
type hw
card 0
}

save it, and restart alsa sound with this command

/etc/init.d/alsasound restart

if u cant restart it, just relogout/ login again. then you can have sound system(minimize/bell) / audacious / youtube website playing sound together.
