I suspect you haven't configured the Video Producer Service to use PAL and saved the configuration. Or maybe you are setting it to PAL directly in VIC, which it'll forget the next time VIC is started. See the following on how to configure a Video Producer: http://www.accessgrid.org/node/1770 you might also like to increase the bandwidth and quality sliders to see if that makes any difference.

Tom, You should have my report of these problems as well as log files from last november. I can dig them up and resend if necessary. And it's not just me, others also have similar issues.

Cameron, Yes, it was me. The larger project is the RIT Global Collaboration Grid, which envisions using the highest possible technology to create a single virtual space for all of RIT's sites. See http://rc.rit.edu/collaborationgrid.html for an overview. The current architecture for this distributed yet coordinated set of nodes is simply standard AG nodes. To reduce maintenance and enable others to contribute with minimum cost and headaches, I have been asked to move closer to an appliance model, where I would specify the hardware and software exactly so that it would be guaranteed to work first time, every time. While I have been reluctant to go in this direction, it's obviously the only way to get the buy-in I need to move quickly and credibly to deploy the collaboration grid. (Actually, I would like to go even further and develop a 'thin-client' ag node but that's another story...). So, we just ordered parts for ten little computers which balanced small form factor with cost from NewEgg and GovConnection. Our original spec was to be able to send one DVTS stream and receive at least five, using the extendedvideoservices in the access grid. We tested the first one with this spec and it passed (except for the onboard GigE) so we ordered ten more but with a PCI GigE card. However, we really probably want to do some H.264/Mpeg4 as well but we need to run benchmarks for that still. Anticipating that we ordered five systems with a dual core processor and five with a quad core processor to see what the difference would be. The mpeg4 encoding has been quite intensive especially when you get up to 720 and 1080 resolutions so it's a real concern. We also required firewire ports for the DVTS. So far, we have only run WindowsXP but intend to try out a linux as well. We are running AG 3.1 b/c 3.2beta breaks the mpeg4 and extended services that we need.

hi, i think this has come up before but i can't seem to recall the solution. i'm using extended video services in AG with DVTS. on some installations DVTS comes up with a black screen even though the network interface shows that 30 Mbps are reaching the computer. but for some reason the DVTS application is not 'seeing' it. is there a known cause or set of possible causes for this behavior under windows? thanks in advance -gurcharan -- ------------------------- Gurcharan S.

Odd Venue Server behavior
by Vine, Derek A 08 May '09

08 May '09

Hello all, I have been having issues with our Venue Server since I first set it up last spring. First, I have never been able to use anything other than the default lobby, the exits would not work for anything that I added. Second, I have had issues using the Data, Services and Application Sessions in the venue. When someone would try uploading a file it wouldn't do anything and then may or may not be there the next time you enter the venue. Third, I recently installed some Windows updates on this machine and after the restart I have not been able to connect to Venue Server with the Venue Management tool, it says unable to connect and logs "SSLError: sslv3 alert certificate expired". I have attached the venue server log. I will be replacing the existing box with a new one sometime this summer and would hope to correct some/all of the issues that I have had over the past year. On a side note, does anyone have a Venue Server running on Windows Server 2003? That is what our server team would like me to use so that they can manage it with the rest of their equipment. Thank you in advance for any assistance.

NAT'ed network issues.
by Jimmy Miklavcic 08 May '09

08 May '09

KUMC and Utah have been trying to track down a problem for quite some time now. KUMC has a NAT'ed network. When running AG, RAT works but it is using the private IP address instead of the public IP. Why is RAT seeing the private address instead of the public address? VIC does not receive each of our video streams. This occurs in both the Argonne Venue Server and our own ArtGrid venue server. We have used four different bridges with the same result. During one trouble shooting session with Mike Miller at NCSA, Mike was able to see traffic passing through his bridge. KUMC is implementing port-forwarding at their firewall and here in Utah we're using public address space. Could there be a router somewhere in between that is not behaving properly? Any help in this matter would be extremely helpful. Thanks, Jimmy -- Jimmy Miklavcic Multimedia Specialist Jimmy.Miklavcic(a)utah.edu<mailto:[email protected]> UNIVERSITY OF UTAH CTR FOR HIGH PERFORM COMPUTING 155 SOUTH 1452 EAST RM 405 SALT LAKE CITY, UT 84112-0190 Office: 801.585.9335 Fax: 801.585.5366 http://www.anotherlanguage.org<http://www.anotherlanguage.org/>

issue with video
by Robert Morrow 08 May '09

08 May '09

we have a system that is using NAT. The audio is working fine but the video is not working at all. We send Jimmy the video but never receive anything back. He never receive video and we never receive his. We have looked at our firewall and we are not blocking anything. It appears that the bridge tries to use our internal ip address and it can not send it back on that address. is there somewhere in for software or a config file I could change to set the system to understand NAT addressing and start using our external address?

Video capture card Advice request
by Khanh ly 08 May '09

08 May '09

Hello All, We are looking to replace the 4-cameras inputs IEI-IVC 200 cards. They are running well on the windows XP machine. However, they gave poor quality on the Fedora 10 system. Even worse, we must configure the video to transmit PAL signal (using H.261) every time we start Access Grid. Could you recommend us the video capture card for using with Access Grid 3.1 with specs: 1. Fedora 10 (preferred 32 bits) and drivers 2. PCI bus preferred 3. Australia Standard PAL-G supported 4. HD resolution is not required yet due to budget limit. 5. Four cameras inputs Thanks for your help Khanh WASP UWA Cawley, WA Australia

Question about AccessGrid small nodes
by Purvis, Cameron 07 May '09

07 May '09

Hello, from Cameron at the University of Alabama! I'm sorry if I have this mixed up: I believe that, in the AccessGrid Town Hall meeting Tuesday morning, that I heard about RIT building out small AccessGrid nodes based on inexpensive desktop computers. I couldn't make out the name of the speaker well but I think it may have been you. The vision was to link several rooms together with standardized units all in a grid venue. That sounds like something that could be a very good demonstration of the technology here in Tuscaloosa, Alabama. It also sounds like something that would be fun to observe as the community starts to play with the technology. If you guys are working on something like that - a sort of standardized design for small nodes - I'd love to be in touch with the right person to talk about that. This is something I'd like to replicate here, and would appreciate the chance to collaborate with RIT. Thanks! -- Cameron Purvis University of Alabama Office of Information Technology, Research ckpurvis(a)ua.edu<mailto:[email protected]> (205) 348-4677

Re: [AG-TECH] Firewall Configuration document for the Access Grid
by Ben Green 07 May '09

07 May '09

Hi Jason, This looks quite useful. However, I think it may over-complicate things for the average user. Firstly, I don't think we need to spend too much time publicising how to run Toolkit servers when there are many potential VenueClient users out there who simply want to get their software running on their PC. If think anyone serious enough to consider running their own VenueServers will find the firewall the least of their worries ! We hear from many first time users who cannot get their VenueClient working due mainly to their institution's firewall and some give up in the end. I've attached a couple of quick documents I've written up that I send out to our users (they cover IOCOM IG Client as well) to help them with the firewall. However, the first only covers Windows users with a public IP address (a typical University user), so doesn't cover every type of situation. And I'm not 100% sure on the range of ports I've specified for the institution firewall - they certainly don't all match up with the document you have written. I currently have 2 AG Toolkit users who are unable to get their firewalls working: 1) A MAC user. 2) Someone on a private network, i.e. a network using NAT. I'm trying to get them both an answer, but I've not used a MAC before, and don't know whether Toolkit traverse NAT networks. Please can you help out with these two issues I've got ? Perhaps documentation exists already in a format that can be given to a new user. The other thing I'm unsure of is the range of UDP bi-directional ports that require opening on the institution/gateway firewall (for unicast users). Your document (http://www.accessgrid.org/node/1816) to suggest a default range of 50,000 to 52,000. But I'm sure when we've installed BridgeServer our range is 10000 - 10999. This part is quite fundamental in terms of getting Toolkit to work via a firewall, and certainly essential information for any client who's network uses NAT.

Hi, Would it be possible to make new VideoConsumer- & ProducerH264 packages out of the latest code from the mpeg4 branch of vic? The newest version fixes a bug with using DV cameras, and since we have a few affiliated remote sites that only have DV cameras and no capture hardware, we'd like to make it easier for them by re-integrating it back into AG proper rather than having to launch the newest vic from the command line and do the config manually.

Hi Andrew, The description should be written in a few days. I will put screenshots with the explanation of how it works. Actually I sort of plugged an OpenGL interface to the existing VIC, adding a new button in the tcl interface that launches it, and adding a function to each decoder and rtp source to get each source's video stream and other useful data to transmit to the OpenGL interface.

Jamie Details for setting up a Venue Server and Unicast bridge can be found on "Access Grid Installation Guide for Fedora 10", see http://www.accessgrid.org/f10-install. There is also information on older versions of the Fedora install guides (See http://www.accessgrid.org/documentation) Obviously this information is if you would like to run the servers on Linux! Additionally, there are some workshop notes that can be found at http://www.arcs.org.au/support/training/video-collaboration-workshop/sch edule (See Day 3 - Venue Servers and Unicast Bridging). Hopefully this should assist in getting you started. Cheers, Jason.

Hi Jason, Sure I can place some information there. This version should be cross-platform indeed, since the libraries used are all cross-platform (OpenCV, GLFW, FTGL, DevIL). However I am not familiar at all with configure scripts, and I have been working modifying manually the Makefile (it is currently working on Ubuntu), though trying to understand how to deal with configure scripts, so this must be sorted out still...

Tom and Andrew I have updated VP on the projects page (http://www.accessgrid.org/project/videopresence) with the new SVN link and also added a link to the VP Binaries.

Also, it might be good for that page to include the binaries from the ANU page (http://if.anu.edu.au/SW/VP.html) or at least link to it. Also, how hard it is for a separate service-type app like VP to access the shared data services from the Venue server that shared apps have? One of the features we want to have is captioning, and I'm not sure whether it would be best to integrate it fully into VP via shared services or to somehow piggyback the text data on RTP for reception within VP with a separate pure Python shared app for entry. --Andrew 2009/5/5 Thomas Uram <turam(a)mcs.anl.gov> Hi Andrew: There haven't been any changes to the VP SVN at UChicago since I imported that code. It was placed there so that people could use and improve it. Due to a recent change in the svn server, you'll want to use the following URL to access that code: https://svn.ci.uchicago.edu/svn/if-media/ Let me know where you got the incorrect URL and I'll make sure it gets updated.
