IP Camera capture
Jan 21st, 2009, 9:24pm  
I'm just diving into this, I did skim thought the reference and have had no trouble capturing from a web cam. I have been considering using processing for a project that involves displaying a video stream from an IP Camera. If anyone could point me in the right direction about how the best way to go about this is, I'd much appreciate it!

Hi

Did you figure something out?
I just ran into the same dilemma, I can't even find a camera where it will let
me capture the images directly from the IP address, and not go through the browser interface first:/

You won't be able to use the Capture class, but you should be able to just do:

PImage img=loadImage("http://192.168.0.2/image.jpg"); //or whatever the URL of the image is when you go in via a browser.

Hi,

I'm trying to do the same thing.

Loading the image works fine but it is very slow. I only get about 4 frames per seconds. I'm loading the image every void draw()

Is there a way to speed it up? or at least let the rest of the program run at normal speed not 4 fps.

So my sensors and other udp network connection keep working normal.



Thanks.

ok, so I'm using an Axis 207w.

I'm not even able to get a slow feed of the images. I get this error over and over again till I kill the program. I'm obviously missing something:

Could not find a method to load http://152.117.205.34/axis-cgi/mjpg/video.cgi?resolution=320x240

EDIT:
what I'm really trying to do is use that video stream in the url I just posted. someone HAS to know how to do this. the company wouldn't include a motion jpeg stream if you can't use it! Processing really seems like the perfect environment to make this easy?

I don't think Processing can use MJPEG by default.. there should be a Java library somewhere that can.. how easy it'd be to integrate with Processing though I don't know.

there appears to be one, jipcam. but thus far, I have been unable to even get it working in a java applet. if anyone has experience with this, it'd be great to get some pointers. thanks

EDIT:

so I have been unsuccessful finding useful documentation on jipCam, but I did stumble across a post on a sun forum with a solution using java without JMF and jipCam.
the 19th post. major kudos to Carl Gould

this has been helping me big time seeing what's going on. hopefully it helps you too. Once I get all my stuff developed based off of this example, I hope to be able to integrate this into a processing app?

//  http://192.168.2.3/jpg/image.jpg
pipe = new GSPipeline(this, "gnomevfssrc location=http://192.168.2.3/mjpg/video.mjpg");
opencv = new OpenCV( this );
opencv.allocate(width,height);
}
void draw() {
if (pipe.available() == true) {
   pipe.read();
