I'm using processing 1.5.1 with GLGraphics and it works very well, expecially if I have to display many images. This because I'm using GLTexture and I'm putting the PImages loaded into textures.

With Processing 2 and OpenGL mode I'll have the same performance?

Thanks

I'm using GSVideo on a machine with installed Windows Server 2008 R2. I'm trying to reproduce videos but the only one I can play is an AVI video. MP4 and MOV video fails, just show gray image.

Any suggestion? Maybe are missing codecs?

Thanks.

is it possible with GSVideo select the sound card to reproduce the audio of a movie file? 

Thanks.

I'm trying the new processing 2.0 and I see that the GSMovie class as been integrated into the video library, now is called Movie.

The same will happen with GLTexture and the others GLGraphics classes, maybe in the opengl library?

Thanks,

I'm trying to port my Processing 1.5.1 project to new Processing 2.0a4. I found an error while calling the screenY method of PGraphicsOpenGL.

This is my code:

1. public void setup()
2. {
3.       size(1440, 900, OPENGL);
4. }
5. 
   
6. public void mousePressed()
7. {
8.       println(mouseY + " - " + screenY(mouseX, mouseY, 0));
9. }

514 - 1414

398 - 1298

It seems that the screenY value is increased by the height of the sketch.

Is this a bug?

Thanks.

1. Thread thread = new Thread(new Runnable()
2. {
3.       @Override
4.       public void run()
5.       {
6.             image = loadImage(filename);
7.             texture.putImage(image);
8.       }
9. });
10. thread.start();

Is it possible to put a PImage into a GLTexture in a thread different from the main?

Thanks.

I'm using GSVideo and I see that in the new version 1.0.0 I should be able to reproduce a movie over http, simply passing the url as filename.

I'm using Eclipse and I wrote this code:

1. private GSMovie movie;
2. private GLTexture textureMovie;
3. 
   
4. public void setup()
5. {
6.       size(1920, 1080, GLGraphics.GLGRAPHICS);
7.       background(0);
8. 
   
9.       textureMovie = new GLTexture(this);
10.       movie = new GSMovie(this, "http://www.fake.com/video.mov");
11.       movie.setPixelDest(textureMovie);
12.       movie.play();
13. }
14. 
    
15. public void draw()
16. {
17.       if (movie.ready())
18.       {
19.             movie.read();
20.             textureMovie.putPixelsIntoTexture();
21.             image(textureMovie, 0, 0, 800, 600);
22.       }
23. }

When run I get this error:

Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded!

GConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details -  1: Failed to get connection to session: Not enough memory)

I forgot something? Or it's a bug?

Thanks

PS: the video doesn't exist, it's just for example.

I cannot install OpenCV library on my Snow Leopard.

First I f ollowed these instructions:

http://ubaa.net/shared/processing/opencv/

installing before the opencv-framework-1.1.dmg and then downloading the OpenCV Processing Library and putting it into the library folder. This is the error I get:

OpenCV ERROR: Internal error (couldnt create new video channel)

Then I try with the beta version found here:

http://ubaa.net/shared/processing/opencv/download/2.0/beta/

And this is the error I get:

QTKit didn't find any attached Video Input Devices!

Warning, camera failed to properly initialize!

Cleaned up camera.

Error while starting capture : device 0

OpenCV could not define source dimensions.

Can anybody help me?

Thanks.

I'vo got problem while loading a lot of images with multithread. I load each image in a separated thread and when is done I resize the image and put it into a GLTexture with putImage on the main thread. When I click on one image, I load again the same image but full size and put it into another GLTexture. All seem to work fine, but while opening more images the smallest ones loose image and becomes white randomly. The same happens randomly while open a big one. I don't know if is something related to the delete() method of GLTexture.

This is a look like piece of code:

private PImage image;

private GLTexture texture;

private boolean loading;

public void draw()

{

      // load the image only 1 time

      if (image == null && loading == false)

      {

            loading = true;

            loadImageWithThread("image.jpg");

      }

      else if (image != null)

      {

            texture  = new GLTexture(this );

            texture.putImage(image);

            image.delete();

            image = null;

      }

      

      if (texture != null && texture.available())

      {

            image(texture, 0, 0);

      }

}

private loadImageWithThread(String filename)

{

      Thread thread = new Thread( new Runnable()

      {

            @Override

            public void run()

            {

                  image = loadImage(filename);

            }

            thread.start();

      });

      thread.start();

}

I'm using the new libraries GSVideo 0.9 (Snow Leopard 64 bit) and GLGraphics 0.99 inside Eclipse 64 bit on MacOSX.

I could play the sample movie station.mov, but when I try to play a big movie (898x506 AAC,H.264 for 17,3MB) the java crash with this error:

This is my code:

import processing.core.PApplet;

import codeanticode.gsvideo.*;

public class Test extends PApplet

{

GSMovie movie;

public void setup() 

{

  size(640, 480);

  background(0);

  // Load and play the video in a loop

  movie = new GSMovie(this, "movie.mov");

  movie.play();

}

public void draw()

{

if (movie.ready())

{

movie.read();

tint(255, 20);

image(movie, mouseX-movie.width/2, mouseY-movie.height/2);

}

}

}

I think it could be a memory issue but I can't solve it.

Thanks for suggestions.
