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


Hi Monika,

Yup, it was a known issue, I mentioned it in a post yesterday evening, but no problem if you missed it.
It was a display problem in the end, for some reason Windows doesn't seem to like doing vsnprintf() with multiple arguments - sometimes. Same code on Linux worked.
VIC and RAT do not automatically start. In the documentation it states how that behavior works, i.e. the '-x' option. For standalone, i.e.'-x', usage, AGVCR also requires the mbone tools to be in the same folder or path as itself. Please see the docs for more.
I've posted a new source tree and windows binary on the website now, it fixes the display problem.

Hi All,

I am currently trying it on XP Pro SP2 with multicast.
Recording seems to work fine (the file got some size).
When playing back, I don't see vic and rat starting.

I am not sure what I am doing wrong. Attached is a snaphot.
Note the "File Offset: .....out of 0 bytes" ????

TIA
Monika




Win XP Pro SP2. Works like a charm in multicast.

Hi Zsolt,

Yea, that's one thing noted in the 'known issues', the
problem with recording from unicast. I'm glad to hear
AGConnector helped, I like that program. There's some old
code in there that I wrote for trying to send data to
QuickBridge (since it seems to need to receive something
in order to send data back to you) but I never did get it
working to any satisfaction.

Since I'm replying to all I was aware (as is typical after
announcing something works) that under Windows now it
appears to have problems with reading or displaying the
file length, something for me to look at tomorrow.

Growing pains I think, I've been rewriting a lot of it
(under Linux for the most part) in the last few weeks as
I've considered more things that I wanted to add, and lo
today I 'got the nod' to release it. So I thought I'd let
everyone take a look instead of me sitting on it a moment
longer. This may be good and bad, but as long as everyone
treats it as 'alpha' for now until more testing is done
then I think we'll all be good. I do not think the file
format will need to change, given all that I have in my
'future plans', so any recordings made now will work in
later versions. If for some reason it does, I will make
available the converter program I have used to convert
previous recordings to the new format.

Thanks for trying it out, incidentally, what version did
you use, Windows or Linux?

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! Zsolt

       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: >


http://iri.informatics.indiana.edu/~dcpiper/agvcr/ >


       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. >


       Thanks,

       Derek
