Art net on same computer

hi. i discovered that i cant instanciate artnet node on same computer that have a WhiteCat running in artnet.

i remember we had before .19 a discussion about this bug, that seems to have come back in 21 and 22.

Have you tried starting vvvv before whitecat?
Acording to Arkaos, the specs allow artnet on the same machine, but I think vvvv wont either share ports or switch to another, I can’t remember the solution I hear now…

hmm…can we get more information about that?

hi … i tried in the 2 ways… whitecat first, then after. node creation of dmx entity is not possible. whitecat doesn t use any dotnet routines, its all along its own dlls. opengl based for graphics. ethernet routines are based on windows.h

Found a little quote from arkaos
Anyway, MagicQ should work with ArKaos DMX on the same machine because arKaos opens the UDP ArtNet port with settings to allow another application to open it at the same time. If Chamsys has done the same it will work and I think they should have done that. However I’m not 100% sure they did. Be sure to use latest Chamsys version, I know it was not possible in the past.
It is possible, and I have run magicq and vvvv on the same pc, but vvvv had to be started first, otherwise the dmx node doesn’t appear in the patch.

and you’d say vvvvs behavior was different before?

we are talking about the DMX (Network Artnet Sender) and DMX (Network Artnet Receiver) nodes, right?

having a peak at vvvvs implementation i’d say it would not work to have another process opening the artnet-port (6454) for listening. if the other app only is an artnet-sender sending to 6454 should work of course from the same machine.

thing is: even if you only want to use vvvv to send artnet, it opens the port for listening. not sure if that is really necessary…

hi joreg …
i will have a look more precisely tomorrow on it. perhaps its me that making problems, opening an artnet listener in my app… and opening the port…

sorry, i come back after a while just to keep you informed…

ok ! shame on me !
sooooooooorrrrry for worring!

catweasel or devvvs, any idea of the name of this way to deal with the sockets ? or wich technique to use ?

sincerely

shame on you? i don’t understand…what have you found out?

i forget that i was opening automatically the server part on each launch of whitecat !
now my problem is: in wich type of socket handling and procedures should i put my code to obtain what is described by catweasel:

karistouf-
Are you currently using Windows 7?
I am having problems making a connection to DMX ArtNET Receiver.
I have successfully used it in the past with both Chamsys Magic Q and Innovate Show Control’s BlueLite X1.

Tried it tonight and am not having success.

I can send data from a vvvv patch with the artnet sender node and receive it with the artnet receiver node.

No luck with an external program.

I am currently using Windows 7 64bit and vvvv beta22.

My previous success was on XP and vvvv beta21.

SORRY JDBIED, I M UNDER XP

i need to learn more about sockets :-(

note:
even if you run only one pc you have to connect to an ethernetswitch/device once to activate the network adapter. otherwise Artnet doesn’t work even within vvvv.

once i was wondering that my artnet patches didn’t work in a train…

127.0.0.1 … works without plugs

i had some issues with the artnet nodes when the computer was not logged into any network.
in that situation the nodes don’t work at all. (no other software involved)

i don’t know if that behavior has something to do with your fiddlings here - but imo it’s a think that should be kept in mind.

@devvs: is that a known issue to you? because that test-environment could be very rare (no network at all… haha)

hi sebl, not logged to any network or no connexion adapter ON on the computer ?
( i m still waiting that devvvs give us ppossibility to specify in inspektor the UDP ort)

you can now start vvvv with option /artnetport 1234. Please report your findings in the alpha forum.
