Hi Guys!

ZM work's fine for me with a single camera (I've used a USB cam for a couple of weeks without problems).

Now my next "project" was to install a multi-port card, so I bought a very cheap BT878 card from eBay.

scanpci -v says:

I've tried a couple of modprobes:

modprobe -v bttv
modprobe -v bttv card=77
modprobe -v bttv card=103

The last one looks quite fine:

Mar 25 17:00:05 bit kernel: bttv: Bt8xx card found (0).
Mar 25 17:00:05 bit kernel: PCI: Found IRQ 11 for device 0000:01:0a.0

Mar 25 17:00:35 bit kernel: bttv0: PLL: 28636363 => 35468950 . ok

So, next was to access the card using ZM and there the story begins. I only got gray images. Is there any HowTo you can recommend how to access multi-port card's? How do I access the four different channels?

So next, does anybody know a 4-port card from "Star Imavision"? The WIndows drivers says something about this company.

I think you have the wrong card type in modprobe. I don't remember which one it was but neither of those that you listed look right.
You should aslo add
tuner=4
So that your config knows that there is no tuner.

Ok, thanks. Now I've tried "modprobe -v tuner=4" and dmesg shows:

bttv0: Bt878 (rev 17) at 0000:01:0a.0, irq: 11, latency: 66, mmio: 0x40500000

bttv0: i2c: checking for TDA9887 @ 0x86... not found

bttv0: registered device vbi0

Doesn't look so good

Does the card look anything like the ones in these ebay auctions:

5739759604
5562033959
5764290694

If so, there is apparently a patch to the bttv driver that should work for this type of card.

The patch was posted to the video4linux mailing list. Digest Vol 11, Issue 6 subject "Patch: Support inexpensive 4 channel 878A 16 input board CS16".

I've not tried it with the card I have yet - I bought a different card shortly before the patch surfaced

HTH,

Jim

Hm, well its one of these on ebay: 5764851703

Sorry, brain failure. It's a single device card.

This thread may provide some leads?

You could also check the bttv gallery to try and identify the card (they're quite often badged/copied/cloned from other designs).

Thank's, I've seen this topic last week but this didn't solve my problems

I try to get some help from the video4linux-list now ...

Well, after doing "try and error" with modprobe and xawtv my card runs fine under xawtv.

I'm using: modprobe bttv card=77 tuner=4

Now I'm trying to access all fout composite ports but ZoneMinder. With xawtv I can choose one of those composite ports, but how do I access them under zone minder?

You choose the 'channel' in the monitor definition, pick 0-3.

Phil

Chip BT8xx is very simple, it has 4 video inputs. Type of card you can select via parameter card=xx. The simplest way to run 4inputs card under your system is selecting id for any 4inputs card without tuner and svideo (for example card=0x4d) and type pll parameter for your board. You must see the crystal frequency on your board: 28 MHz => pll=1, 35 MHz => pll=2. i.e. "insmod bttv card=0x4d pll=2" (or pll=1) and card must work now OK.

Thank's sometimes I'm stupid

Well, now I'm fine accessing all four ports using the channel option. But, I'm only able to fetch grey-pictures.

xawtv told me color encoding is done using "bgr4" which seems to be quite different to encoding shemes supported by ZM. I've tried all encodings but only got "funny" images.

Grey is ok, but color would be nice

Select Capture Palette RGB24, the same resolution for all channels and try restart all zmc daemons on this device (or zmpkg.pl restart). On xawtv you have correct color picture?
