Where in the world is my video input device?

[PercentSevenC]

Well, I picked up an old ATI All-in-Wonder Mach64 the other day for $3 hoping I'd be able to do some simple video input.

I installed gatos with no apparent problems. I can see a picture with xatitv, but the screen gets corrupted, obviously a memory allocation issue. With every other TV program I try, though, it can't find the device at all.

xawtv:

This is xawtv-3.95, running on Linux/i686 (2.6.17-10-generic)
can't open /dev/video0: No such file or directory
v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/video0: No such file or directory
v4l2: open /dev/video0: No such file or directory
v4l: open /dev/video0: No such file or directory
no video grabber device available

tvtime:

Running tvtime 1.0.1.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/me/.tvtime/tvtime.xml
videoinput: Cannot open capture device /dev/video0: No such file or directory

    Cannot allocate enough off-screen video memory.  This may be fixed by:

      1. Closing or restarting large X applications.
      2. Lowering the input width of tvtime (--inputwidth parameter).
      3. Lowering your colour depth or highest configured resolution.
      4. Increasing the amount of video memory in your X config file
         (for example, if you are using the i810 XFree86 driver.)

Thank you for using tvtime.

There are no devices called video* in /dev/. When I installed tvtime and xawtv it gave me this both times:

Creating video devices in `/dev'.
udev active, devices will be created in /dev/.static/dev/

Sure enough, there are 64 devices called video* in /dev/.static/dev/ but when I point the TV programs to them manually it still says there is no such device. I tried stopping udev and then installing tvtime and xawtv and restarting udev, and the above message went away, but there still doesn't seem to be any video input devices in /dev/.

Here is the output of xawtv -hwscan:

This is xawtv-3.95, running on Linux/i686 (2.6.17-10-generic)
looking for available devices
port 65-65
    type : Xvideo, image scaler
    name : ATI Mach64 Back-end Overlay Scaler

Can anyone shed some light on this?

Re: Where in the world is my video input device?

In general, udev is the solution, not the problem. I strongly suggest that you take a look at Writing Udev Rules. I don't recall that this HowTo mentioned video explicitly, but you should be able to figure it out from the examples that are given. What is the adress of the video card on the PCI bus from lspci?
