How to Install Video for Linux 2 on vanilla Redhat 9 Linux systems.

Installing Video for Linux 2 on vanilla Redhat 9 Linux systems

Install Redhat 9. Do all the following as root.
Go to ATrpms, where there are three sections you need to fetch an rpm from.
- atrpms: from which you want the package atrpms-VER.rh9.at.noarch.rpm. You probably want the highest numbered 'VER' (if there's a choice, which currently there isn't).
- kernel: from which you want the package kernel-TYPE-VER.rh9.at.ARCH.rpm. TYPE is either nothing (for a uniprocessor), smp (for a multiprocessor), or bigmem (for a >4GB machine). You probably want the highest numbered VER. ARCH is either i586 (old Pentiums), i686 (almost anything sensible Pentium), athlon (AMD CPUs), or i386 (should work with anything vaguely *86-ish). Most current systems will probably need either i686 or athlon. It's important to remember which TYPE/VER/ARCH you picked.
- Finally, you'll need a V4L2-enabled driver for the particular chipset in your video acquisition card. For bttv chipsets, go here and download the package bttv-kmdl-TYPE-VER.rh9.at-BVER.rh9.at.ARCH.rpm where TYPE, VER, and ARCH match those from the kernel package, and BVER is the most recent (if there is a choice, which currently there isn't). For saa7134 chipsets, go here and download the package saa7134-kmdl-TYPE-VER.rh9.at-SVER.rh9.at.ARCH.rpm where TYPE, VER, and ARCH match those from the kernel package, and SVER is the most recent (if there is a choice, which currently there isn't).
Install all the rpms in the usual way (rpm -i).
Reboot your machine into the new kernel.
Make sure the file /etc/modules.conf has a line like "alias char-major-81 bttv" (substitute saa7134 for bttv if your video card has a saa7134 chipset). Redhat's kudzu hardware detector will normally insert this line automatically.
For bttv chipsets, you need to hide the 0.7 variant bbtv module, to make sure that the 0.9 variant is the one which is run. To do this, type "chmod 000 /lib/modules/VER.rh9.at/kernel/drivers/media/video/bttv.o", where VER is the kernel version above.

Note that installing a new kernel might break other kernel modifications you've made to the vanilla Redhat 9 distribution. You may find that the ATrpms site provides drivers for other hardware (eg. nvidia graphics cards) that are compatible with the new kernel. You may also find that installing ATrpm's custom kernel-source rpm will be of use if you need to build modules for hardware not supported under the standard redhat-9 distributed kernel.
