hauppauge wintv input source

hi
i am trying to use an analogue camera with an hauppauge wintv card for an augmented reality device. my problem is that i cannot set the svideo input for vdig when starting beginvideo in processing. is there a way to set the default source in the registry or in vdig?
i tried to set it in hauppauge's tools and in hacktv. but next time i am starting processing the source is the tv imput again.
thanks

Do you know how to select the source (s-video, composite etc) in 070?
Thanks
Chris

Had a similar problem. Don't know if it has the same solution though.
http://processing.org/discourse/yabb/board_VideoCamera_action_d_isplay_num_1107140778.html
Code:
boolean newFrame = false;
void setup() {
size(320, 240);
try{
quicktime.QTSession.open();
quicktime.std.sg.SequenceGrabber sg = new quicktime.std.sg.SequenceGrabber();
quicktime.std.sg.SGVideoChannel sc = new quicktime.std.sg.SGVideoChannel(sg);
quicktime.std.sg.VideoDigitizer vd = sc.getDigitizerComponent();
println( "dv.getNumberOfInputs :" ); println( vd.getNumberOfInputs() ); println();
//change line below to set input source
vd.setInput(1);
//
println( "dv.getInput :" ); println( vd.getInput() ); println();
} catch (Exception e) {
e.printStackTrace();
}
beginVideo(width, height, 4);
}
void videoEvent() {
newFrame = true;
}
void loop() {
if(newFrame) {
background(video);
newFrame = false;
}
}

Unfortunately Processing 068 just hangs for me when I try that code. I am on XP and hvae Quicktime for Java & WinVDIG.
I can't try it in a later version as doesn't like beginvideo()

can you try to run this?
Code:
void setup(){
size(100,100);
try {
quicktime.QTSession.open();
quicktime.std.sg.SequenceGrabber sg = new quicktime.std.sg.SequenceGrabber();
quicktime.std.sg.SGVideoChannel sc = new quicktime.std.sg.SGVideoChannel(sg);
quicktime.std.sg.VideoDigitizer vd = sc.getDigitizerComponent();
println( "dv.getNumberOfInputs :" ); println( vd.getNumberOfInputs() ); println();
println( "dv.getInput :" ); println( vd.getInput() ); println();
quicktime.std.sg.DigitizerInfo di = vd.getDigitizerInfo();
println( "DigitizerInfo :" ); println( di.toString() ); println();
} catch (Exception e) {e.printStackTrace();}
}

does this hang as well?

Nope, I get a little window. Success it seems, partly. Output I get:
--------
dv.getNumberOfInputs :
2
dv.getInput :
1
DigitizerInfo :
quicktime.std.sg.DigitizerInfo MinDestHeight: 240 MinDestWidth: 320
maxDestHeight: 240 MaxDestWidth: 320
blendLevels: 0 InputCapabilityFlags: 5383
OutputCapabilityFlags: 436232192
-------
[edit]
It appears to be BeginVideo that causes it to crash, which is very strange. I've seen my capture card working in WinVDIG and use it in other applications like Eyesweb & Jitter.

good! i think beginvideo hangs because it's desperately trying to read from the wrong input --- staring into the black hole --
it reports 2 inputs and is set to input 1, so logic dictates to try port 2 i guess 
Code:
void setup(){
size(100,100);
try {
quicktime.QTSession.open();
quicktime.std.sg.SequenceGrabber sg = new quicktime.std.sg.SequenceGrabber();
quicktime.std.sg.SGVideoChannel sc = new quicktime.std.sg.SGVideoChannel(sg);
quicktime.std.sg.VideoDigitizer vd = sc.getDigitizerComponent();
// trying port 2 ... not sure if this is zero-based ...
vd.setInput(2);
// see what is says now ...
quicktime.std.sg.DigitizerInfo di = vd.getDigitizerInfo();
println( "DigitizerInfo :\r" + di.toString() + "\r" );
} catch (Exception e) {e.printStackTrace();}
// check if beginVideo() works now ...
beginVideo(width, height, 15);
}
void videoEvent() {
newFrame = true;
}
void loop() {
if(newFrame) {
background(video);
newFrame = false;
}
}
