Fantastic Derek, thanks! One thing. In bridged unicast the recorder can not establish connection with the IPs and ports listed. However, in multicast (even with the AG Connector) it rocks!

Subject: [AG-TECH] Release of AGVCR - recording AG sessions

        Hi all,

        I'm happy to announce that finally I've been given the go-ahead to
release AGVCR to the community. It was a program I started writing
around January and it was ready for release in a workable incarnation
some time in June. However, due to possible 'intellecual property'
concerns from 'those that deal with those things' at IU, I was unable to
release it back then. I declined to mention it to the community at large
until this release so as not to 'tease' people with a product they could
not get. I won't get into griping about that on this list :> Some of you
have known about this program earlier since we have had AccessGrid
meetings that I have recorded. For those parties concerned, we can
communicate off-list on the best way to get the recordings to you.
        AGVCR is a program to record and play back the RTP/RTCP stream that an
AccessGrid conference uses. The amount of data it gathers is certainly
non-trivial, a few hours of recording with a number of participants can
easily reach a few gigabytes in size. Timing and minimal overhead
information is embedded in the file for accurate playback.
        The website for the project is here:


        I invite anyone interested to take a look, download and use it to see
what you think. I welcome feedback, please bear in mind though that it
is still being actively worked on. A number of changes have been made of
late, so testing has not been as extensive as it probably should  be,
but that's another reason to get it out there. The website has  source
for Linux/Unix and a precompiled binary for Windows. I may add
pre-compiled binaries for popular Linuxes if there is interest.
