Hi Well never mind. I think it is this VX VB causing probs here.

Hi Just noticed when testing VX/VB that one of my capture inputs/vic was sending a huge amount of data across Our network. Vic settings were 708 kbps/25 frames/h261. It was something around 16 to 20 mb/s and even higher so it could look like a dv stream. reinstalling modules bt878 and bttv fixed. I'll install never vic and monitor if this happens again. I'm using ivc-200G quad capture card(four bt878 chips) on Fedora 6 kernel 2.6.20-1.2962.fc6 and vic that comes with VenueClient 3.0.2 Lassi Quoting Todd Zimmerman <toddz(a)sfu.ca>: > Lassi Ylikojola wrote: >> Hi ! >> >> Apologies since I think I'm to blame here.

Venue Client Runtime Error....
by Robert Gatlin 31 Jul '07

31 Jul '07

One of the professor's computer here is having some trouble starting the Venue Client. It is Windows XP SP2 and is running AGTK 3.02. I installed everything in the correct order, and if freezes when configuring the UI. I ran the debug and it has two runtime errors at the bottom. The logs are included in an attachment. Any help will be appreciated. Robert Gatlin Technician II Research and Graduates Studies Office 409-741-4076

AG3.1 Bridge error
by Nathan Gardiner 30 Jul '07

30 Jul '07

Hi all, I was hoping someone might be able to shed a little light on the problem that I'm facing setting up a AG3.1 Bridge Server. Below are details of the error I get when I attempt to start bridging. [aguser@ag3bridge ~]$ Bridge -p 20200 -u http://www.accessgrid.org/registry/peers.txt -n "NZ" -l "New Zealand" Traceback (most recent call last): File "/usr/bin/Bridge", line 187, in <module> main() File "/usr/bin/Bridge", line 182, in main bridgeServer = QuickBridgeServer(name=options.name, location=options.location, listenPort=options.listenPort, qbexec=options.qbexec, portRange=options.portRange, registryUrl=options.registryUrl) File "/usr/bin/Bridge", line 47, in __init__ self._RegisterWithRegistry() File "/usr/bin/Bridge", line 84, in _RegisterWithRegistry self.validSecs = self.registryClient.RegisterBridge(self.bridgeDescription) File "/usr/lib/python2.5/site-packages/AccessGrid3/AccessGrid/Registry/Regist ryClient.py", line 75, in RegisterBridge return self.serverProxy.RegisterBridge(registeredServerInfo) AttributeError: 'NoneType' object has no attribute 'RegisterBridge' Anyone come across this before?

> Access Grid Community: > What other desktop sharing technologies does the AG community use other > than VNC? VPCScreen does a pretty good job especially if you have the new SUMOVER UCL vic installed (e.g. the one that comes with AG 3.1 beta) which has H.261AS support. With the VPCScreenProducerService set to H261AS, just click on an Arbitrary Sized window and it will start streaming at that resolution and the receiving vic will display it at that resolution. Some of the benefits using VPCScreen is that the latency is fairly low compared to VNC and SharedPresentation, you can record using AGVCR and it does multicast. VPCScreen home page: http://sheriff.anu.edu.au/~rhys/VPCScreen/ Another AG application sharing tool you could look at is MAST, see: http://www.eminerals.org/highlights/MAST/ Doug

Todd: An unrelated bug has been filed against vic on OSX: http://bugzilla.mcs.anl.gov/accessgrid/show_bug.cgi?id=1673 but as part of it, a new executable has been built with some new network-related code. It would be great if you could run some tests with this newer executable.

AG3.1 Vic on OSX Issues
by Todd Zimmerman 27 Jul '07

27 Jul '07

Wondering if anyone else is experiencing problems with the OSX vic build for AG3.1. On our setup, we have a OSX box doing the video consuming - and a linux box doing the vid capture. The linux box can see all of the incoming (muted) sources, however the OSX box shows no incoming video at all. I've tcpdumped on both the bridge machine and the local OSX box and there are definitely incoming packets from the bridge; however vic shows no video. The fact that there are packets arriving seems to rule out firewall - so I'm left with vic as the problem. I've tried using vic as a VideoService on the OSX box and sending out via iSight camera also. Vic does show the iSight - but still no incoming video. I have got the video feeds to appear once; however I can't replicate it. I believe it started in some combination of starting a second vic from the command line and sending a feed out to the bridge... but like I said, I can't replicate it. I'll file a bug report but wanted to make sure it wasn't a local issue first.

500 Terabytes and growing ... issues
by Jeffrey Miller 26 Jul '07

Hello all, Well. I tried. Seems that the software I used to convert our videocomera composite input was set to its default..PAL M! Made in China and that is their default. Once I figured that out..then the InSORS camera config had to be set to .264 VGA. I got it all up around 11:45! We DID record it so I'll convert it and then post to the grid community.somehow? Sorry. I have this all configured now.so please don't ignore my next announcement. Sorry.I tried. Jeff Jeffrey L.
