Default video capture feature on geforce fx 5200

Hello,

I recently buyed a new computer, (preinstalled Win XP of course)
which features composite and S-VHS video acquisition, located
on the video card and connected to the front panel.

I was wondering if the recent Linux Driver made available
by Nvidia (thanks for supporting the Linux Community !)
deals also with video acquisition.
I've seen in Win XP that there the driver is called "WDM".

I've unterstood that video acquisition takes place via
extra hardware that is wired to a proprietary port on
the nvidia chip. Is that right ?

I aim to capture video from my analog camcorder to record it on DVD.
I would also like to install Linux on that computer.
Before doing that and maybe loose the Win XP installation, I just
want to make sure that I will be able to do the job with the linux
drivers.

Thank you in advance for your advices / your help !

Best regards,

Alain

(Athlon XP 3000 + , 512 Mo RAM, Debian Woody (3.0))

Look for the rivatv project: http://rivatv.sf.net.

They made a driver which allows you to use the tvin part. It is supposed to work on geforcefx cards too. Performance might not be that great and further the nvidia drivers don't like the rivatv drivers much, so be warned.

I have tried this but these drivers do not work on the FX 5200.
Certainly not when running the nVidia drivers at the same time, as you pointed out already.

It needs further research ( & development).
It would be better when nVidia supported video-in and tv-in in their driver. When they don't, some more documentation and maybe entrypoints in the driver are needed, so the modified rivatv driver can call the nvdia module to perform certain chip accesses without disturbing the nvidia driver.

I guess for now the answer is: it is not possible.

Thank you very much for your help !

Instead of desinstalling totally Win XP (and asking
for the licence money back), I'll try to make Win XP and
linux coexist on my system.

If nVidia does at some time include the video capture in
the linux driver, I would appreciate if someone could let me know.

Best regards,

Rivatv doesn't work.
The project is dead in the water and unmaintained. The authors don't respond to calls for help.
Your best bet is to sell your nvidia card and buy one that works with Linux.
