OK so I installed Zoneminder again…
But no video

so the card is there…
are there any other terminal commands I can do to check this card etc… I have full access and SSH access

[freetibet]

Looking for video pan or equivalent so I can see vide from my 8 chip bttv card…
is there any if so how to install ?

[doktor5000]

Maybe you forgot again to configure your system properly for this card?
Check again viewtopic.php?f=8&t=3998

[doktor5000]

Video Lan, video pan, what is your post about? You need an equivalent for what exactly?

Use cheese or vlc or something else to see if the video device is usable ... For installation check https://wiki.mageia.org/en/Software_management
Apart from that, it's quite frustrating if we answer the same question again and again, if you had already solved that before. Please document your setup this time so next time you don't have to ask the same again.

[freetibet]

No I put in a /etc/modprobe.d/bttv.conf file and also for good measure put a one liner in the modules.conf file

[pete910]

Are you planning to use zoneminder with it?

But like Doc said, you can use cheese/vlc to view the inputs

If you wish to see if the driver has loaded open a console as root and do

Code: Select all

lsmod | grep bttv

You should have something like this.

Code: Select all

[root@srv1]# lsmod | grep bttv
bttv                  106506  2
v4l2_common             8560  1 bttv

[root@srv1 modprobe.d]#

[isadora]

this is what I get

Code: Select all

[root@localhost cctvadmin]# lsmod | grep bttv
bttv                  126808  3 bt878

[freetibet]

OK CHeese see's all the inputs but no video coming in…

[pete910]

Is Zoneminder chowing anything?

Also change your buffers to 32. Works better on the 8 chip

[doktor5000]

I've merged the two threads together as they're about the same problem ...

[freetibet]

OK how do I change the buffers to 32 ?
You mean in the monitor settings in Zoneminder… OK done that , no joy.

[pete910]

No I mean in the bttv.conf file!

In fact post the full line that's in the bttv.conf file.

Mine looks like this .

Code: Select all

options i2c-algo-bit bit_test=1
options bttv gbuffers=32 card=102,102,102,102,102,102,102,102 radio=0,0,0,0,0,0,0,0 tuner=4,4,4,4,4,4,4,4 combfilter=1 chroma_agc=1 coring=1 full_luma_range=1

Notice that gbuffers is set to 32!

Here's Zm's cam setup for my card on the first input .



If your seeing just a black screen when you view the monitor, change the colour settings to 32768 in the monitor window (caught me out this one )

[doktor5000]

yep colours were set to 32768 by default
/etc/modpobe.d/bttv.conf

is

Code: Select all

options i2c-algo-bit bit_test=1
options bttv gbuffers=16 card=102,102,102,102,102,102,102,102 radio=0,0,0,0,0,0,0,0 tuner=4,4,4,4,4,4,4,4 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1 autoload=0

I also for good measure edited the modules.conf file

/etc/modules-load.d/modules.conf

Code: Select all

# /etc/modules: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line.  Comments begin with
# a `#', and everything on the line after them are ignored.
options i2c-algo-bit bit_test=1

[doktor5000]

Please next time use code tags as explained in ftp://ftp5.gwdg.de/pub/linux/mandriva/m ... e_tags.ogv

[pete910]

No need to put the same line in both modules.conf and bttv.conf.

What is ZM coming up with when you view the input? (Blue/black/etc no input warning...)

Is Zm throwing any errors? /Warnings? in the log

Do you know for certain the camera(s) are working?

This is whats shown when no cam is connected



Is the correct value for the cams selected in the monitor set up as is like mine in the screen-shot above ?(Pal/NSTC colour format etc)


Pete.

[freetibet]

that is exactly what I see

[pete910]

that is exactly what I see

If that's what your seeing your card and Zoneminder is working fine, Its your cameras that ain't!, presuming you have the correct input selected that is. (/dev/video0 /dev/video1 etc)

[freetibet]

yep

[pete910]

yep

Please mark the topic solved.

[doktor5000]

Yep what? Yep you recognised the problem, but what is the solution?

[pete910]
