hi there people i m in urgent desperate for help
i have a deadline in a few weeks and am having trouble getting my concept to work.



I m tryin to view a series of webcams through processing and i keep getting the same error
cannot load library gstreamer-0.10

this is on all eg.s in the gstreamer library??


import hypermedia.video.*;
import codeanticode.gsvideo.*;

GSPipeline pipe;
OpenCV opencv;

void setup() {

 size( 320, 240 );

  pipe = new GSPipeline(this, "gnomevfssrc location=http://admin:1234@168.192.2.3:4321/mjpg/video.mjpg");
 //pipe = new GSPipeline(this, "gnomevfssrc location=http://192.168.2.3:4321/axis_cgi/mjpg/video.cgi?resolution=640x480 ! jpegdec ! ffmpegcolorspace");
 opencv = new OpenCV( this );
 opencv.allocate(160, 120);
}

void draw() {
if (pipe.available()){

 pipe.read();        
 opencv.copy(pipe, 0, 0, 640, 480, 0, 0, 160, 120);    
 image( opencv.image(), 0, 0);              

 opencv.absDiff();                          

 image( opencv.image(OpenCV.MEMORY), 160, 0 );  
 image( opencv.image(), 160, 120 );            
 }
}
void keyPressed() {    
 opencv.remember();  
}






any ideas GRATLY RECIEVED!!!:D

AND LAST BUT NOT LEAST

What system are you using (windows, linux, mac)? And what version of gsvideo?

Hi,

The error descriptions you have posted so far are not detailed enough to isolate the source of the problem.

However, I see a couple of issues:

* gsvideo on windows 7 64 bits: I don't have windows 7 myself at this point, so I cannot really test this. But some people reported that the latest gsvideo works fine on win7, although I'm not sure if they are on 32 or 64 bits. I'd recommend you remove any previous version of gsvideo/gstreamer from your system, install the latest release of gsvideo (0.6-pre3) and test the provided examples (such as Movie/Loop or Pipelines/Test). If they run ok, then the problem is not windows. If the don't run, please post the full error message you get in Processing.

* GStreamer pipeline to implement RTSP client: I never tested this functionality myself, so my experience is very limited. All I can say in this regard is that the element you are trying to use, gnomevfssrc, is only for Linux. I think the Windows equivalent is rtspsrc. Sample pipelines I found online for rtspsrc are like this:

Code:

rtspsrc location=rtsp://elphel:554 ! queue ! rtpjpegdepay ! queue ! jpegdec ! queue ! videorate ! capsfilter caps="video/x-raw-yuv, format=(fourcc)I420, width=(int)1024, height=(int)768, framerate=(fraction)25/1
 

however I don't know enough about video streaming to be able to provide much help here. The elements you have to put in such pipeline (rtpjpegdepay, etc) probably depend on what encoding you are using to stream out the video.

I have repleaced gsvideo with the latest version as advised now i have the error

ii have the same error

unsatisfiedLinkError Could not load library g streamer-0.10 library
is there a missing plugin or extension of some sort to the

Many thanks

I m using windows vista 64 bit.

unsatisfiedLinkError Could not load library g streamer-0.10 library
the library has been expanded as it was i havent moved anything.

When i run the examples the sketch e.g pixelate has the same error as above?

/**
* Pixelate  
* by Hernando Barragan.  
* Built-in video library replaced with gsvideo by Andres Colubri
*
* Load a QuickTime file and display the video signal
* using rectangles as pixels by reading the values stored
* in the current video frame pixels array.
*/

import codeanticode.gsvideo.*;

int numPixels;
int blockSize = 10;
GSMovie myMovie;
color myMovieColors[];

void setup() {
 size(640, 480, P3D);
 noStroke();
 background(0);
 myMovie = new GSMovie(this, "station.mov");
 myMovie.loop();
 numPixels = width / blockSize;
 myMovieColors = new color[numPixels * numPixels];
}


// Read new values from movie
void movieEvent(GSMovie m) {
 m.read();
 m.loadPixels();
 
 for (int j = 0; j < numPixels; j++) {
   for (int i = 0; i < numPixels; i++) {
     myMovieColors[j*numPixels + i] = m.get(i, j);
   }
 }
}


// Display values from movie
void draw()  {
 for (int j = 0; j < numPixels; j++) {
   for (int i = 0; i < numPixels; i++) {
     fill(myMovieColors[j*numPixels + i]);
     rect(i*blockSize, j*blockSize, blockSize-1, blockSize-1);
   }
 }
}

example code displaying the same error as posted in the message above.

    print ("   hello    ");
 }
 print ("   not found   ");
}

// all cameras to stream creating 2X2 Grid Positioning co ordinates will be needed

above is the code i m using to attempt to capture the streams live from cameras?

I was having the same problem "UnsatisfiedLinkError: could not load library gstreamer-0.10", also using Windows 7 64bit and gsvideo-0.6-pre4.  I was using processing 1.09.  After upgrading to processing 1.1, everything works great.

Thanks so much for your library!

The gnomertspsrc element is available only on linux
