Hi Derek, We'd certainly appreciate anything you can uncover- the AGVCR seems to crash at random, even when it's not playing or recording anything. Sometimes it will record fine for 45 minutes and never freeze, and other times it will lock up after 10 minutes, recording or not. When it does freeze while recording, it always corrupts the file being recorded. I agree that it's probably some windows-specific glitch- unfortunately, that's what we're running on our machines, which are 'former' InSors cubes. Any help you can offer would be great- thanks again for getting back to me so fast with the GTK update. Even with the crashes, AGVCR is still an impressive piece of work!

Re: [AG-TECH] Bridge server

> Given the importance/need for many of us to statically assign bridge ports, will this functionality > be available in AG3? Can you elaborate this point more? What is currently in AG3 is this: - A Bridge can be run with a particular port range specified. The person running the bridge will have to ensure that these ports are open for udp through their firewall. - A user will see which bridges are available, and can view the hostname and port range used by each. The user can then decide which bridges to use, and pass this information to a network admin to open ports accordingly. Questions this leaves open: - What should the default port range for a bridge be? How about 50000-50200? This would ensure that bridges will, by default, all use the same (relatively) narrow port range. - Is this sufficient for your local networking needs? There may be something additional implied by 'statically assign bridge ports', and I'd like it to be explicit so I can address it. Tom On 4/19/06 11:44 AM, Todd Zimmerman wrote: > Agreed.

I'll take a look at that. My previous email may not have been as clear as I'd intended it to be. wxPython 2.6 (spec'd for AG3.0bx) doesn't work with the AG2.4 Shared Browser. But wxPython 2.5 works for both AG2.4 and AG3.0b2 Shared Browser. So, I'll install the latest version of wxPython 2.5.x. My concern is the issue of AG3.0 not working correctly in some ways with wxPython 2.5 or 2.5.x. I'm pretty sure that Tom explained that at some point when discussing the move from wxPython 2.5 to wxPython 2.6 for AG3.0. Thanks. --fred

The change happened sometime in the wxPython 2.5.x series, you are most likely using a earlier version of wxPython 2.5 which supports both wx.iewin and wx.lib.iewin modules.

23 Apr '06

Update to the AG Tech / AG Users Community: Please, if you can forward this to any lists that you're a part of in your community (as appropriate), it would be appreciated. SC Global'06 Submissions are still open and have been extended to May 26th. SC Global'06 is a showcase of collaborative technologies and is open to all SC06 attendees. Portions of SC06 are available to those who can not attend through SC Desktop. I encourage anyone who is involved in collaborative technology (using/making it happen/stories) to submit to SC Global'06. The door is wide open; the twist this year is the emphasis on the high-end technologies that enable working collaborations as the main focus for SCGlobal'06 - any collaborative technology. This year's SC06 is in Tampa: Information: http://sc06.supercomputing.org/conference/scglobal.php Questions: scglobal(a)sc06.supercomputing.org Thanks, John Q. -- John I.

wxPython 2.6 with AG2.4
by Fred Dech 21 Apr '06

21 Apr '06

Since yesterday, I've been wondering what the incompatibility is between wxPython 2.5 and AG3.0b2. I've had AG2.4 and AG3.0b2 installed on the same WinXP node for some time with no problems. As was posted a while back, wxPython 2.6 isn't completely compatible with AG2.4. I'd not run into this first hand until we were doing some shared-app tests yesterday and, as was posted, the Win Shared Web Browser (IE) did not work for AG2.4 with wxPython2.6. The browser works fine with AG3.0b2/wxPython2.6. It also works fine for both AG2.4 and AG3.0b2 with wxPython2.5. So, I've reverted to wxPython2.5. BTW. I do not have the CVS versions of either AG installed. Has this wxPython version issue been addressed? It's not a big deal yet, since 3.0 isn't used in production , at least for most people. But it will become an issue when both AG2.4 and AG3.0 are used regularly in a production setting. I'm sure there will be a significant time overlap before everyone upgrades their nodes to AG3.0. So, dual installs will be pretty important for a period of time. --fred

Re: [AG-TECH] AG 3.0 beta 2 - Video Capture not working
by Thomas D. Uram 21 Apr '06

21 Apr '06

Hi Nathan: What you are hoping for is intended to be possible with AG3. I have confirmed this working with a Winnov videum card and with multiple USB and firewire cameras, all at the same time (I have an iTuner Spectra, too; I'll have to try that). I'll try to help you resolve the problem to ensure that AG3 will do what you're after. A couple questions: - Do you have VFW or WDM drivers installed for the card? - Do the individual spectra capture devices appear in vic? (Select Menu, then the Device button) Cheers, Tom On 4/20/06 11:39 PM, Nathan Gardiner wrote: > Hi there, > > I am testing out the AG 3.0 beta 2 downloadable from the Access Grid > website.
