blank screen after 2 or 3 hours: zmc or bttv?

davide · Post by **davide** » Fri May 21, 2004 10:41 pm

hi all,

I don't know the source of this problem, could be zmc or a wrong installation of bttv or whatever..

Today I got black images from /dev/video0 after 3 hours of modect, I restarted zm, all ok but after 2 hours black screen again, and so on..

system specs:
VIA vt8235, duron 1200, RAM 256 DDR, video capture card: grandtec (card=103).
buffer ring = 60
only 1 source, capture size: 384x288 RGB 565
LiveCD installation with zm upgraded to 1.19.4 (so its mandrake kernel version 2.6.3-4mdk)

here are 2 cut&paste from /var/log/messages:

Hi Davide,
Try booting with "noapic" or "pci=noacpi" or both.

When you say 'blank screen', do you mean that the video just stops displaying in your browser or that the capture daemon is capturing blank images?

Phil,

davide · Post by **davide** » Sun May 23, 2004 9:49 am

Hi Phil,
i mean capture deamon starts capturing blank images in the exact moment bttv logs this in /var/log/messages

Code: Select all

kernel: bttv0: timeout: irq=825088/825088, risc=0859336c, bits: HSYNC OFLOW

every time the error occurs zmc logs a sync failure error, then bttv logs a timeout, here is an example:

Code: Select all

May 23 08:27:29 videoserver zmc-d0[2474]: ERR [Sync failure for frame 0: Input/output error]
May 23 08:27:29 videoserver kernel: bttv0: timeout: irq=2571375/2571375, risc=081623dc, bits: HSYNC OFLOW

May 23 08:29:15 videoserver zmc-d0[2474]: INF [uno: 858000 - Capturing at 8.93 fps]

then zmc continues capturing images but these are blank

davide,

rdmelin · Post by **rdmelin** » Sun May 23, 2004 2:08 pm

lilo.conf and dmesg look right. Does the problem persist?

Ross

davide · Post by **davide** » Sun May 23, 2004 2:24 pm

I am testing right now.
videoserver is up and nice working from 11:50 (16:15 now)

I will wait till tomorrow morning before exult...

I'll let you know how it goes.

Thank you.

PS.
Are these problems frequent or rare? What are they caused by? How to avoid such problems? did I choose a wrong motherboard? Should I use standardATX instead of MicroATX to avoid such problems? How to choose right?

davide · Post by **davide** » Mon May 24, 2004 11:20 am

the problem seems solved, boot parameters work well, the videoserver is capturing without any problem..

thank you Ross!
