RE: [AG-TECH] Vic.exe error

When you configure the camera, what format are you selecting? The maximum video that vic can handle is something like 352x288. It usually crashes if it cannot handle the resolution chosen. Andrew :) Access Grid Support Centre, RSS Group, Manch

[AG-TECH] What Version of OS X for Macs Works?

Short Story: Last week, I was running OS 10.3.7 ... and I successfully installed the software needed to support AG client and got the client to work. Tonight, with 10.3.8 -- my system freezes. Long Story: I could not get our dept Logitech camera to work, so I bought an iSight. It wouldn't work

Hi Don: I believe (based on other conversations with you) that you're using multicast addresses similar to 224.0.0.x on your server. This is, apparently, a problem. From the cisco Guidelines for Enterprise IP Multicast Address Allocation (http://www.cisco.com/en/US/tech/tk828/technologies_wh

Hi Kathy, 15" Powerbooks don't require a powered microphone. You can use the internal microphone. When the iSight is plugged-in, just make sure the default audio input device stays set to the built-in audio device, and everything should work fine. So, you shouldn't need to return the iSight, bu

[AG-TECH] Audio on Mac PB - was Mac OSX AGTk 2.3 with Media Tools Release

On a G5 Power Mac, a powered microphone is required to send audio -- the line-in port does not work with standard computer microphones. I have a 15" G4 powerbook (fall04 model). I have an iSight camera -- and was aware that RAT probably wouldn't recognize the sound-in from it

We're running the latest AccessGrid Toolkit on MacOS X, as both a VenueServer and a UniCast Bridge for that VenueServer. The server is multicast enabled, and so are clients on the upenn.edu network. Clients on the upenn.edu network can connect to the VenueServer and use RAT and VIC just fine.

RE: [AG-TECH] VIC performance

Just a thought - some network cards auto-negociate between 10 Mbit and 100 Mbit and this can cause the net data rate to be closer to 10 Mbit, even when both ends are capable of 100. We have found that it is better to set some to 100 Mbit manually, rather than letting the card and router negociate i

Re: [AG-TECH] VIC performance

One way to tell what is going on is to mute all of the video streams. when muted, all vic is doing is parsing the packet streams, and not decoding the h261 (as I recall anyway). It is definitely not rendering them. If you still see frame loss with streams muted, it is most likely the network at

Natalia, It's difficult to provide feedback without knowing a bit more. The total video rate will depend on the processor speed, graphics card, etc., but mostly on the network bandwidth the display machine is seeing. We had a single processor 1.4 GHz Athlon with a G200 (4 output) display card, an

Eric et al, Is anyone working on expanding the OSX client to be able to select from more audio sources? In particular, can it (or will it be able to) take audio from a USB source such as iMic? If this were working, one could use any mic-level or line-level source. I haven't actually tried this
