<P><FONT size=2>Hi Zsolt,<BR><BR>Yea, that's one thing noted in the 'known
issues', the problem with recording<BR>from unicast. I'm glad to hear
AGConnector helped, I like that program. There's<BR>some old code in there that
I wrote for trying to send data to QuickBridge<BR>(since it seems to need to
receive something in order to send data back to you)<BR>but I never did get it
working to any satisfaction.<BR><BR>Since I'm replying to all I was aware (as is
typical after announcing something<BR>works) that under Windows now it appears
to have problems with reading or<BR>displaying the file length, something for me
to look at tomorrow.<BR><BR>Growing pains I think, I've been rewriting a lot of
it (under Linux for the most<BR>part) in the last few weeks as I've considered
more things that I wanted to add,<BR>and lo today I 'got the nod' to release it.
So I thought I'd let everyone take a<BR>look instead of me sitting on it a
moment longer. This may be good and bad, but<BR>as long as everyone treats it as
'alpha' for now until more testing is done then<BR>I think we'll all be good. I
do not think the file format will need to change,<BR>given all that I have in my
'future plans', so any recordings made now will work<BR>in later versions. If
for some reason it does, I will make available the<BR>converter program I have
used to convert previous recordings to the new format.<BR><BR>Thanks for trying
it out, incidentally, what version did you use, Windows or
Linux?<BR><BR>Derek<BR><BR>Quoting "Nagykaldi, Zsolt F. (HSC)"
<Zsolt-Nagykaldi@ouhsc.edu>:<BR><BR>> <BR>> Fantastic Derek,
thanks! One thing. In bridged unicast the recorder can not<BR>> establish
connection with the IPs and ports listed. However, in multicast<BR>> (even
with the AG Connector) it rocks!<BR>> <BR>>

Grid Technical mailing list<BR>> Subject: [AG-TECH] Release of AGVCR -
recording AG
sessions<BR>><BR>><BR>><BR>><BR>>
Hi all,<BR>><BR>> I'm
happy to announce that finally I've been given the go-ahead to<BR>> release
AGVCR to the community. It was a program I started writing<BR>> around
January and it was ready for release in a workable incarnation<BR>> some time
in June. However, due to possible 'intellecual property'<BR>> concerns from
'those that deal with those things' at IU, I was unable to<BR>> release it
back then. I declined to mention it to the community at large<BR>> until this
release so as not to 'tease' people with a product they could<BR>> not get. I
won't get into griping about that on this list :> Some of you<BR>> have
known about this program earlier since we have had AccessGrid<BR>> meetings
that I have recorded. For those parties concerned, we can<BR>> communicate
off-list on the best way to get the recordings to
you.<BR>> AGVCR is a program
to record and play back the RTP/RTCP stream that<BR>> an<BR>> AccessGrid
conference uses. The amount of data it gathers is certainly<BR>> non-trivial,
a few hours of recording with a number of participants can<BR>> easily reach
a few gigabytes in size. Timing and minimal overhead<BR>> information is
embedded in the file for accurate
playback.<BR>> The website
for the project is
here:<BR>><BR>> <A
href="http://iri.informatics.indiana.edu/~dcpiper/agvcr/">http://iri.informatics.indiana.edu/~dcpiper/agvcr/</A><BR>><BR>>
I invite anyone interested to take a look, download and use it to<BR>>
see<BR>> what you think. I welcome feedback, please bear in mind though that
it<BR>> is still being actively worked on. A number of changes have been made
of<BR>> late, so testing has not been as extensive as it probably
should be,<BR>> but that's another reason to get it out there. The
website has source<BR>> for Linux/Unix and a precompiled binary for
Windows. I may add<BR>> pre-compiled binaries for popular Linuxes if there is
interest.<BR>><BR>>
Thanks,<BR>><BR>>
