VDIG (www.vdig.com/) is no longer available
Sep 25^th, 2007, 12:05pm

Now there is a commercial version produced by www.abstractplane.com and commercialized as try and buy.
I tried it with a Logitech Express web cam (super basic) and I could not get it to work.
Therefore I turned to JMYron and I found it pretty usable (apart from a blue screen and bad documentation).
I suggest to migrate all the references and examples from VDIG to JMyron.
Let me also ask: why has only abstractplane addressed the problem of creating a quick time compatible digitizer? Why don't we ask the JMyron guys (J.Nimoy - http://www.jtnimoy.net) to extend/branch from their webcamXtra project (http://webcamxtra.sourceforge.net/)the portion related to the digitizer?
BUT most important. AM I THE ONLY ONE WILLING TO USE VIDEO CAPTURE AND PROCESSING UNDER WINDOWS? Wink

ciao

the vdig.com site goes offline time-to-time (sometimes for several days), not sure if they're gone for good or not.

unfortunately there just isn't a clear cross-platform video solution. the fact that lots of people are coming to this board to get support for jmyron tells me that jmyron is not getting enough support itself. i may try using jmf (java media framework) for windows and quicktime on the mac, but jmf is also unsupported and doubles the amount of code that i have to maintain. i think jmf may also be limited to the old WDM drivers on windows, which means only 320x240 video support. we could also tie in our own c code via a dll, but again, that gets much more complicated.

any help in this area is most certainly welcome...

Thanks for the clarification. Actually I tried (just 4 fun) to install jmf and run a simple test I found on the jsf forum (http://forum.java.sun.com/thread.jspa?threadID=626262&tstart=45).
Actually those few lines of code did the job: now I can see my cam image on my screen (WIN XP home edition, logitech cheap cam, on a standard HP pavillion laptop).
Hence my new question: has anyone experience in creating quick time extensione in java under windows? If so let's create a *S I M P L E* video digitizer and open up the fantastic world of Processing video capture to those poor win users (At the end of the day... are they so few? I can't believe it!.)
let me hear your voice guys!

i believe we can find a java based solution on video capturing and processing in 2 ways.
1. use opencv with jni. i think this is hard and requires top-notch java developers.
2. use jmf with java2d and jre 6.0n which uses directx.
this one should have a good performance and easier to develop. i am not sure what is the limit for jmf with regards to frame rate and size, but it should be ok for most apps.

Uhm, i'm not sure with your point 2. Since the processing "capture" library relies on QuickTime, I guess that the only doable way is that ov building a digitizer extension for QT, much in the way VDIG and abstractplane did.

I see another alternative: combine the excellent work don by the jmyron guys with the interfaces provided by Apple to creat e QuickTime extensions: yes I'm talking C++.
I'm not much into it but I guess QuickTime has good and clear interfaces for cam capturing drivers extensions (can anyone expert take a look at http://developer.apple.com/reference/QuickTime).
If so we might use the camera digitizer component by Jmyron and interface it to QT.
easy? don't know... maybe since VDIG stopped working on it and astracplane made it commercial, it must not be so straightforward.Or simply there's not that much demand for it.

i forgot to mention that for option 2, the capturing with jmf will be a standalone java application, not processing. so we will capture video with jmf, process and write the pixels to a buffer with Java2D. After that, we can send only that pixel buffer to Processing. So, because no capturing is made inside Processing, in theory, we don't need any QTJ, or VDIG libraries, just jmf.
