[AG-TECH] Issues with a new AG 3.1 installation.

[Douglas Kosovic]

Hi Miguel,

You might like to try setting the VideoProducers to V4L instead of V4L2 and see if you get similar issues.

Sorry I'm not sure what the cause of the issue is, but will try to reproduce next week.

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,
