saa7134 surveillance

Hi!
I have a surveillance card with saa7134 chips. It should be able to
see 8 cameras at a time, but there is only 4 video devices in /dev of
this card.
These devices are working fine, each device's channel 0(there isn't
any other channel of these devices) is an input for a camera.
So, how could I manage it to be 8 devices?

dmesg:

Introduction needed to set up my radio/tv card Bt878

Hi All,

i want to set up my tv/radio adapter to listen to my favorite music 
channels.

i have the following adapter:
>            +-14.4-[0000:03]--+-03.0  Brooktree Corporation Bt878 Video Capture [109e:036e]
>            |                 \-03.1  Brooktree Corporation Device [109e:0868]

At this time i am compiling a new kernel with the module bttv.

Any additional advice for me ?
What modules do i need ?

regards Markus

Kernel-version ? Newer kernels allow you to set v4l subsystem to 
"allocate minor device numbers dynamically". This is supposed to allow 
more than 4 devices on a single card, according to the help-text of the 
2.6.29 kernel I just compiled.

Caveat: All this is from memory, ~24hours old.

Re: saa7134 surveillance

I have 2.6.28 version kernel(The default with ubuntu jaunty). But I
had checked the documentation of 2.6.29 and saw that the v4l framework
redesinged a bit...so I have to compile the 2.6.29 kernel to see all
the cameras? Nice...but I will try.
Anyway: Thanks for the reply!

that won't help.

We had always support for at least eight saa713x chips.

Do you have four such chips on the board or eight?

Cheers,
Hermann

Re: saa7134 surveillance

It has 4 chips only, and 2 D-SUB-like input, and it has four-four
coax(for video) and eight-eight RCA(for sound) cable per input.
If you wish, I could make a picture of it.

if it has only four chips, it can only support four inputs at once.

The idea having 8 cameras at once is realized only in software then,
by switching between at least two inputs per saa713x.

The card=0 only has one input per saa713x chip, so you should add the
second one for each. Have a look at saa7134-cards.c.

In short, it likely is only a software and not a driver problem.

Only if the TS/DVB input is used at once, the chips can handle two
inputs at the same time. Some (likely unsupported) hardware mpeg/TS
encoder there?

Cheers,
Hermann

Can you take a photo of the card?

ffmpeg can do that:
ffmpeg -f video4linux2 -s WxH /dev/video out.avi
