[mythtv-users] no /dev/video device in Gentoo, help

[David Latka]

I just had the same problem getting ivtv to work on Gentoo.

The discussion thread might help.

ring=HELP%21%21%21;guest=1845817&t=search_engine#95095

Of particular help was this link:
http://forums.gentoo.org/viewtopic.php?t=71263&highlight=ivtv

In your particular case, make sure your /etc/devfsd.conf has the following
lines in it:

# Video4Linux devices
REGISTER v4l/.* PERMISSIONS root.video 660
REGISTER ^v4l/video0$ CFUNCTION GLOBAL mksymlink v4l/video0 video0

The symlink line will create a symlink in the /dev directory which points
video0 to v4l/video0

Hope this helps,
Dave Latka

Greetings fellow Gentoo users.

I'm dying here.

I just switched this week from redhat 7.2 on my server to gentoo
gs-sources (since it's a smp server) and for the life of me can't get
ivtv modules to load.

So upon doing some checking found the machine does see the pvr-250 card.
When I run # cat /proc/pci

<!------------------ Begin Code ----------------->
Bus  0, device  20, function  0:
    Multimedia video controller: PCI device 4444:0016 (Internext
Compression Inc) (rev 1).
      IRQ 11.
      Master Capable.  Latency=32.  Min Gnt=128.Max Lat=8.
      Prefetchable 32 bit memory at 0xd4000000 [0xd7ffffff].
<!--------------------End Code --------------->

However when I check /dev there is NO video listed.

I doubt I'll be able to load ivtv modules if there is no video device in
/dev... any ideas how to fix this?
I've never seen this happen before.

Thanks all.

- Jeff
