Problem with bt 878 based card

[coffeepot76]

hi,
I have some problems in ZoneMinder with two cards pico2000 rev 2.0 (conextant fusion 878A based ). In the past I used
successfully these cards with an older PC on which I installed the zm live distro, today I migrated to a newer PC (i686
Pentium (R) Dual-Core CPU E5400@2.70GHz) on which I've installed Sabayon 2.6.34 and ZoneMinder v1.24.2.

In modprobe.d I've posted a bttv.conf with:

options i2c-algo-bit bit_test=1
options bttv card=77,77 tuner=4,4 radio=0,0 triton1=0 vsfx=0 autoload=0


The cards are identified by zm, which marks them sources in orange.
In Window monitor instead I get a broken image link, if I change image
option into mpeg I get a white image. I've tried to switch from v4l1 to v4l2 but nothing change.

From zmu -d /dev/video0 -q -v i've obtained:

so i think that the problem could be in the messages:

bt878 #0 [sw]: bus seems to be busy
bt878 #1 [sw]: bus seems to be busy


Someone have any suggestion?

thanks in advance.

Try changing Captures_per_Frame value from 1 to 2 or more. From the value description: If you are using cameras attached to a video capture card which forces multiple inputs to share one capture chip, it can sometimes produce images with interlaced frames reversed resulting in poor image quality and a distinctive comb edge appearance. Increasing this setting allows you to force additional image captures before one is selected as the captured frame. This allows the capture hardware to 'settle down' and produce better quality images at the price of lesser capture rates. This option has no effect on (a) network cameras, or (b) where multiple inputs do not share a capture chip. This option addresses a similar problem to the ZM_V4L_MULTI_BUFFER option and you should normally change the value of only one of the options at a time.

Hi bb99,
now ZM_V4L_MULTI_BUFFER is off and CAPTURE_PER_FRAME is 8 but nothing change.

[bb99]

Try leaving multi buffers off and lower the captures per frame to 2 or maybe 3 at most. Connect only one camera per card for troubleshooting and disable any other defined monitors so you only have to change one per card. Double check the settings on the monitor source tabs to insure they're the same as with the live CD set up except for the capture palette and width / height. Change width / height to 320 / 240; as for the palette: you're going to have to experiment with this to find the correct one. An example: using a PV-149 with 1.23.3, I used RGB, with 1.24.2 I have to use BGR24. Mostly what you've posted looks good so I think it will be this simple.

Verify blacklists in modprobe directory, can be blocked.

Looks like an irq problem on the bus. From the messages as per below and the others.

Try moving the card to the first slot available then boot up and see how it goes.
check for options on bios for the slots the capture card is fitted too.

I have seen a pci capture card stop a motherborad dead not even post in the past.
Both motherboard and pci card work fine in other boards but not together.

I had a lot of trouble setting up the card that you have in the past. Would only
work on certain motherbords. and in certain slots

IRQ 11/bttv1: IRQF_DISABLED is not guaranteed on shared IRQs

WHat chipset is on the main board. As above id try running with only 1 card to start with. I have had loads of issue with non intel mobos
