Problem with PCi-E card combination of CX25853 and CX25821

[p3k074]

Hi,

I have problem with start working Zoneminder with PCIE card with two chips onboard : CX25853 and CX25821. This is 8 channel dvr h264 pcie capture cards - made in china. I installed UBUNTU with all updates and Zoneminder. All fine Zoneminder start working but problem is no video from this card.

I think all looks fine but not work:

I dont have any idea how do this card usable ... If any can help will be great ...

You have to recompile kernel module with this patch http://comments.gmane.org/gmane.linux.d ... ture/44985. Current kernel module doesn't have definition for generic card. I followed this guide for recompiling module http://wiki.centos.org/HowTos/BuildingKernelModules.

Hi Radek,

How many video channels you get working? What exact card model you managed to work?

Regards,
Marcin

[xmasin]

Hello,
I get working all 8 video channels, in /dev/ you can see video0 - video11, but devices video8 - video11 are audio channels from decoder, so you can use only first 8 channels for Zoneminder. I have bought this card http://dx.com/p/8-ch-h-264-dvr-video-ca ... ntsc-42242.

Have you tested the cx25858 chip video card, use the ZM program?

Thank you

Hello,
unfortunatelly no, because I have only card with CX25853 and CX25821 chips.

Hello!
I have a similar problem. But the link to the patch is no longer available. Tell me at least what it was about, what keywords should I google for?

[vadegdadeg]

I figured out this problem!
My card contains:
CX25821-11Z
CX25853-12Z
Four sound ADC ES7240S
And two EEPROM's 24C02 and AT88SC0104CA this is "super-puper" Atmel CryptoMemory

At the beginning, I looked at the VID/PID of my card:

Code: Select all

03:00.0 0400: 14f1:8210
        Subsystem: 5644:4e4c
        Flags: bus master, fast devsel, latency 0, IRQ 17

        Capabilities: [200] Virtual Channel
        Kernel driver in use: cx25821
        Kernel modules: cx25821

And if 14f1:8210 are standard, then subsystem is different from 'reference'...
By searching for the words 14f1:8210, I found these values ​​​​in the source.
I replaced 0000/0000 with my values ​​obtained from lspci.
File: cx25821-core.c

Code: Select all

static const struct pci_device_id cx25821_pci_tbl[] = {
        {
                /* CX25821 Athena */
                .vendor = 0x14f1,
                .device = 0x8210,
                .subvendor = 0x14f1,
                .subdevice = 0x0920,
        }, {
                /* CX25821 No Brand */
                .vendor = 0x14f1,
                .device = 0x8210,
                .subvendor = 0x5644,
                .subdevice = 0x4e4c,
        }, {
                /* --- end of list --- */
        }
};

And it worked!

But there was another problem, the sound does not work!
When cx25821-alsa is loaded, the module loads normally, a sound card appears in alsamixer, but without controls.
And if cx25821-alsa is unloaded and then mplayer is started, the system goes into kernel panic...
But I was warned that IDs should be:

It only works with boards with function 01 enabled. To check if your board supports, use lspci -n. If supported, you should see 14f1:8801 or 14f1:8811 PCI device.

I'll figure it out if the ADC board is soldered for nothing ...

Desoldered EEPROM, and reading it. The board didn't work without EEPROM, the 'subsystem' field disappeared.
You can see the identifier, circled in red, but I still didn’t understand about the first byte, a quote from the source (cx25821-alsa.c):

/*
* PCI ID Table - 14f1:8801 and 14f1:8811 means function 1: Audio
* Only boards with eeprom and byte 1 at eeprom=1 have it
*/
