Can't install TV-card: /dev/v4l/video0 missing


Hi.

I've installed a TV-card (Hauppauge WinTV GO2) but obviously Linux needs /dev/v4l/video0 to make it work, but I can't find anything like that in /dev.

What do I have to do to create that. (It's working fine in Windows XP).
I use a Mandrake kernel, so I believe TV-card support is already compiled, isn't it?

Appreciate your help.

Have you enable Video 4 Linux option in your kernel??? when your module is inserted, have you error messages ??? Because, this device (/dev/v4l/video0) is created at module insertion.

I'm quite new to Linux so I haven't compiled the kernel myself. Mandrake Linux says they have build-in support for V4L.

Do I have to compile the kernel myself?

Happy Birthday !!!

Can you give more detail about your problem? Have you tried to use xawtv?
What is the result of the command 'xawtv -hwscan'?
On my PC, running Mandrake 9.2, I got this :
====

root@sun vincent]# xawtv -hwscan
This is xawtv-3.88, running on Linux/i686 (2.4.22-10mdk)
looking for available devices
port 61-61 [ -xvport 61 ]
type : Xvideo, video overlay
name : video4linux

port 62-62
type : Xvideo, image scaler
name : NV Video Overlay

/dev/v4l/video0: OK [ -device /dev/v4l/video0 ]
type : v4l

flags: overlay capture tuner

/dev/v4l/video1: OK [ -device /dev/v4l/video1 ]
type : v4l

flags: capture

===
I have installed Mandrake without compiling it myself.
Please tell us more,

Vincent

same problem

I suffer the same error message from the xawtv command, but when I modprobe bttv I don't get a fix, I get the following error:

[root@localhost matt]# modprobe bttv
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/bttv.o.gz: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
modprobe: insmod /lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/bttv.o.gz failed
modprobe: insmod bttv failed

Any help would be gratefully received.

Matt

I get the same prob when I do modrobe bttv. But I think Oliv' is right, video 4 linux does need to be activated. I dont know if this is defautly turned on, so I am going to recompile my kernel and if that works, I will post back.

I also have a Hauppauge WinTV GO2, and I have a SuSE 9.0 distro. The YAST configuration system did not detect the card (probably because the card is newer than the OS version?), so I tried some manual things.

I tried modprobe bttv, but that gave the same error as on your system. I think that the bttv module does not support this card. So I searched for other modules (look in /lib/modules/[kernel]/maybe_something_more/v4l2), and as the winXP drivers had names with 880, 881 and 88x in it, I tried cx8800 and cx88xx:

modprobe cx8800
modprobe cx88xx

(maybe you can skip one of these)

and then
modprobe tuner
modprobe tvaudio

(I don't know if the last one is a good thing)

Then start a TV app, select the frequency settings (europe-west for me), video format (PAL for me) and select a channel manually (autoscan didn't work for me). The result was that motv (a xawtv-based app) displayed a black&white TV window with no sound, but it shows that I'm close to a solution.
