Re: [AG-TECH] macbook pro video (vic) troubles

On bended knee and with humility, I beg that Tom Uram's vic2.exe please be bundled in the 2.4 distribution of the AccessGrid Toolkit installer executable.

It solves this problem. When the first vic (sometimes the only vic) opens, it finds out it is the first (or only) vic and it will use the port assigned by the venue serve to send out video streams. This has same effect that rat does on firewalls and will open firewall ports to allow returning, incoming video streams on the same port. Subsequent vics processes started for the venue session by the client will revert to the behavior we're accustomed to seeing (random port selected for outgoing stream). See http://bugzilla.mcs.anl.gov/ accessgrid/show_bug.cgi?id=1228 for more information.

The new vic is included in 3.0.2

Making the change to the 2.4 installer would save incredible amounts of time lost to multiple end users and their AccessGrid support staff. I'm hoping that it won't take too much time to change the installer but I'm confident that the return of total time to the community will be a thousand fold.

It would be great to see this "fix" in the UCL-SUMOVER version as well.

Desperately and Humbly yours,

Joe

Hi,

The port displayed within vic is the receiving port. The sending port can be found by running some tool that displays which applications are using which ports (Active Ports for Windows seems good).

Hi,

I'm having the same problem in a firewall situation myself.  In the
VIC window I can see the port assigned and verify that it is within
the allowable range on the firewall.  From the explanation below, it
would appear the the port on the VIC window is the sending port.  Is
there an easy way to verify which is the receiving port to make sure
that it is within the allowable range?

Hi,

This kind of sounds like a firewall problem.  RAT uses the same
port for send and receive and so may poke a return path on the
firewall for incoming traffic.  Vic uses different ports for
sending from receiving, and so doesn't do this.  The odd thing
about this is that it works when you close the video consumer
service - I have never known that to work, but maybe it sends out a
packet from the receive socket as it closes?

I'm have 2 of the newer macbook pro's (core 2 duo) which are
causing me
video problems. These are both being run off a unicast network and
using a bridge for the connection.
I can configure the the hardware and software which runs properly
locally. However I can't view other peoples video in vic (I
can hear and see them in rat, but their video does not show up in
vic).
I have tried using a single VideoService like most of my other
personal
nodes, but this only displays the capture source, I have then
setup both
VideoConumerService & VideoProducerService, but the
VideoConsumerService
instance of vic stays blank. It is only when I remove
VideoConsumerService from my node that the VideoProducerService
displays
all offsite video streams, which I then have to unmute to view. This
setup is, however, not stable and does not work all the time.
Has anyone else experienced any problems similar to this, and if
so, is
there a solution to it at this time?
