Hello,
I'm currently testing a new AcessGrid 3.1 installation with 2 computers;
- The first one is a Linux Fedora Core 9 (kernel: 2.6.25.3-18.fc9.i686)
with 4 video capturers connected to 4 cameras. This computer is working
as H264 video producer with a Service Manager launched.
The 4 video capturers are Pinnacle PCTV Rave (chipset: Conexant FUSION
878A).
- The last computer is under Windows XP SP3 working as a H264 video
consumer.
I start the AGServiceManager on the linux computer and then on the
windows computer i launch my venue client and i configure there the
consumer and producer video services. When i connect to my venue
everything works fine; vic gets launched i can see all the videos
perfectly and smooth but after a few time, (about 20-30min) one of the
cameras freezes completly (it's random the camera that freezes) and i
start getting the same error all the time in the console where i
launched the ServiceManager:
ioctl VIDIOC_DQBUF: Input/output error
Also if i check the dmesg output i get errors there, for all the other
devices (bttv1, bttv2 and bttv3):
bttv0: SCERR @ 369d9000,bits: HSYNC OFLOW FBUS SCERR*
bttv0: timeout: drop=41 irq=114623/114624, risc=369d9000, bits: HSYNC
OFLOW FBUS:
I have checked if the video capturer cards where being loaded with the
right module and driver and seems they are.
At this point i don't what else i should check or do, so if anyone got a
clue about what's wrong any kind of help would be appreciated.
Greetings,
