* Amazing! *

Well, I must say: AMAZING!

I've had my LMLBT44 card sitting here for 1 year (purchased june 2003) and I got to install it over the last few weeks along with a few cameras.

It took a while to figure out all the LMLBT44 and Zoneminder issues, but now that this is all working, I must say I have not been this amazed since Virtual Hosts came out on Apache

If you have any questiond I'd be glad to help.

I'm on Redhat 8.0. I tried to compile a custom kernel for the LMLBT44 card, but this requires more tweaking than I expected to make all the other services on the involved server work.

For now, I'm using the defalt bttv.o module. If only I could get all 8 inputs to work I'd be even happier...

PS: I'll be sending my contribution this week Philip!

Just a quick comment about LMLBT44. I set up a machine for a client with this card and ZoneMinder running on Mandrake 9.2, stock kernel. The trick to get all 8 inputs working was:
1. Remove all lines related to bttv from modules.conf
2. There was no 2. That was it. It just worked.

Thanks! That's also what seemed to make the most sense to me... Here's what I've sent to LML for support:

#4 - PROBLEM: I can not enable /dev/video4 to /dev/video7

Here is the message when I launch xawtv:

This is xawtv-3.74, running on Linux/i686 (2.4.20-28.
Warning: locale not supported by Xlib, locale set to C
can't open /dev/video4: No such device
v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/video4: No such device
v4l: open /dev/video4: No such device
no video grabber device available

I currently do NOT have any specific options loaded for bttv in modules.conf.
Any help will be appreciated.

Here is modinfo for the default bttv.o module:

And another "glitch" / "issue": I can only see 2 streams at a time when I call up the MONTAGE or multiple windows...

rdmelin · Post by **rdmelin** » Tue Jul 13, 2004 4:45 am

Im not sure how much help I can be, as I no longer have the card, and my memory isn't what it once was, but here goes. The LMLBT44 has 4 bttv chips, so will be /dev/video0 thru /dev/video3. Inputs 5 thru 8 will be on channel 1 or 2. So input 1 in ZoneMinder would be /dev/video0(0) and input 5 would be /dev/video0(1 or 2). I wish I could remember which channel for sure. You could test whether both inputs that share a bttv device are working by plugging cams into inputs 1 and 5, and running xawtv -c /dev/video0. The sources in xawtv will be "television" (channel 1), "composite1" (channel 1), "svideo" (channel 2), and composite2 (channel 3).

The issue with montage may be that your system resources are tapped out. Are you using cambozola, or native mjpeg stream? Two streams at 9 FPS, apache, mysql, X, netscape... is a pretty fair load. Have you tried viewing from another machine?
