Re: Re: Installation V4L2 — Video for Linux

First. I must apologise for sending 5 times the same mail. I hate webmail because this situations.

I could install vanilla kernel 2.4.22 from kernel.org and after patching it with kraxel patch in my full instalation of RH 9 it just works.

The goal of running a bttv v4l2 driver is to keep opened my bttv device more than once for development of a real time application .

Thanks to all that help me.

Hi,
I worked only in Red Hat linux. Have a close look into the
following link. http://bytesex.org/v4l/build.html. This says

" If you run in trouble with the distribution kernel, try a vanilla
kernel from kernel.org instead. The RH9 kernel for example doesn't
work without some tweaks in the drivers source code because they
backported lot of stuff from 2.5.x and broke source level
compatibility with vanilla 2.4.x kernels ".

So do as follows.

Download Vanilla kernel 2.4.22 from www.kernel.org
Download "patch-2.4.22-kraxel.gz" from http://bytesex.org/patches/
Apply the patch to the kernel source.
Compile the kernel with
1) loadable module support
2) Multimedia devices -> Video for Linux -> Video Adapters -
<M> BT848 Video For Linux (as Module)
in make menuconfig.
Boot the new kernel Image
Download bttv version 0.9.11 from "http://bytesex.org/bttv/"
Compile bttv
load bttv driver 0.9.11
When u load bttv driver using modprobe, there may be possiblity of
old driver loaded again. so rename the old bttv driver and load new
driver.

Try this one out and if u have any problem, revert back.

There is no substitution for hard work.
