No audio when running VLC and RAT simultaneously w/ Linux (CentOS)??
by Andrew Leahy 08 Sep '09

08 Sep '09

Hi, we seem to have contention issues with the audio devices when using RAT and VLC (VideoLan Client). Scenario - an academic wants to play a video file (MPEG) during his AG session and have it appear at the remote sites. Our first idea was to use VLC on all the AG display machines (running VenueClient/RAT/VIC). Audio coming out of the local display machines should be treated the same as audio coming from remote AG sites, which should play into the room, be echo-cancelled by our ClearOne units before going into Line-In, so in theory it shouldn't end up echo'ing back at the remote sites. When we stream the video using VLC (either in multicast or point-to-point) without RAT running, the video & audio plays fine. However, if RAT is running, the video plays but there's no audio. Not "no audio" like it's being echo-cancelled, it's "no audio" as though VLC isn't even trying. I suspect RAT is "locking" the Linux audio device? I can probably dig up error messages for this, unfortunately I'm remote from the machines right now. Host machines - Linux mix of CentOS5.3 and Fedora Core 8. AGtk 3.1 Does anyone have suggestions for working around this? If it "should work" we'll keep trying harder! At the moment, it looks like we'll have to use another machine in the AG rooms (connected to the room audio) and make sure RAT is muted so we don't cause echo.

Hi Douglas, I was able to use your instructions for this with the following comments: > The assumes the patch file wasn't downloaded to the home dir (i.e ~/ ), "wasn't" = "was" :-) The vic loaded into the browser as a page - I was able to resave it as a file from the browser window. You might check that, it'll throw some users that it wasn't downloaded as a file in both cases - the patch and the vic. Copying the vic file I found those directories on my OS X machine under /.AccessGrid3/local_services/VideoConsumerService, etc. Works. In fact, just off the top of my head - I noticed the new vic displays the h261as previews... Just fine! And the producer vic, while hidden, actually shows up. :-) After un-hiding the producer vic I was able to play around (on my MBP - 3 year old+ 2.33Ghz model) and send video in h261as in 640x480, then crashed it sending mpeg4 video, then h264 video worked... But of course processor intensive. Great. -John Q. -- John I.

Bonjour Tobias I used your xml file and now the portlet is listed in Pluto so I could create an Accessgrid Page with PAG 1) **** With the version I am using (pluto-2.0.0 bundle), I had to change: <servlet-class>org.apache.pluto.core.PortletServlet</servlet-class> to <servlet-class>org.apache.pluto.container.driver.PortletServlet</servlet-class> 2) **** I also had to install the xerces (last version: xerces-2_9_1) libraries for XML parsing Then with Linux I still have (as on your test server at Manchester) the message "there is a bug in Java..... accessing certificates.. please restart your browser..." but (I already know that) restarting the server does not help so I tried with other machines (Mac OS X and W. XP) There I could fill the form and click on "GO", it seems that I can enter a venue but no more and I get these "Content is not allowed in prolog" errors in catalina.out which probably generate the java exceptions: java.lang.NullPointerException at pag.servlet.tags.XmlRpcGetResponseTag.doTag(XmlRpcGetResponseTag.java:57) ...

I'm not working for the AGSC so I'm not in the position to comment on the official AGSC position on PAG.

The PAG reference server works for me fine with the AGSC venue server.

There is no direct development on PAG, but as the JISC VRE 3 OneVRE project is very dependent on PAG, bug fixes will be coming in and feature requests will be considered if they fit into the OneVRE concept.

Hi Tyler, Snow Leopard comes with both Python 2.5 and 2.6, so with a bit of modifications I was able to get the Intel AG 3.2 beta to work, here are the steps: After installing Intel AG 3.2 beta, download the following patch file: http://www.vislab.uq.edu.au/ag3/macosx/10.6/AG-3.2-beta-patch.txt Then on the command-line: cd /Applications sudo patch -p0 < ~/AG-3.2-beta-patch.txt The assumes the patch file wasn't downloaded to the home dir (i.e ~/ ), change appropriately if downloaded elsewhere. The patch replaces the existing shebang first line with #! /usr/bin/python2.5 and python2 with pythonw2.5 in a number of files. The VIC that comes with AG 3.2 beta doesn't seem to work. After running the VenueClient at least once, download a newer vic built on Snow Leopard from: http://www.vislab.uq.edu.au/ag3/macosx/10.6/vic then copy it to one or more of the following locations: ~/.Accessgrid3/VideoConsumerService/ ~/.Accessgrid3/VideoService/ ~/.Accessgrid3/VideoProducerService/ Doug > -----Original Message----- > From: ag-tech-bounces(a)lists.mcs.anl.gov [mailto:ag-tech- > bounces(a)lists.mcs.anl.gov] On Behalf Of Douglas Kosovic > Sent: Tuesday, 1 September 2009 10:43 AM > To: Tyler Heaton > Cc: ag-tech(a)lists.mcs.anl.gov > Subject: Re: [AG-TECH] Mac OSX 10.6 > > Hi Tyler, > > > Has anyone heard of potential problems with Accessgrid running > > on the new OSX?

Tobias, what is the official AGSC position on PAG? I looked at this on paper a while ago and it would seem to address many of the problems of using AG within an organisation. However, I never got it to work on the AGSC venue server (in terms of seeing any streams - it connected to the venue server with no problems) and I assumed that it was still in a development phase (the Wiki mentioned in the support link below isn't generally accessible, and the blog hasn't been changed since July last year).
