Hi, to rule out a potential issue with your opengl drivers (which could lead to the glew32.dll error), why don’t you try some application that requires opengl?

You could use glgraphics, for instance.

I tried 2 different versions:
The newest gsvideo-0.6-pre5
and
gsvideo-0.5.
Both show the same problem.
But I am not really shure, if I have a gsvideo or an OpenGl problem.
I am currently testing several different processing applications on that pc and applications that use gsvideo OR OpenGl give me unsatisfiedLinkErrors.
I have a due date beginning next week, so I think I will have to survive without OpenGl and gsvideo (which is hard but possible).
Of course any ideas on this subject are very welcome.

What version of gsvideo are you using?

I did a fresh installation and gsvideo on an XP PC.
I have problems with gsvideo, this includes the examples.
If I run any of those examples I get the error message:
cant load library glew.32dll with -Djna.library.path=D:/sketchbook/libraries/gsvideo/library\gstreamer\bin last error: java.lang.UnsatisfiedLinkError:Unable to load library ‘glew32.dll’Modul not found.
Looking into that directory I can see the grew32.dll.
I have no idea what to.
Any help would be greatly appreciated.

Thanks for sharing this hack.

The example works as expected, no problem.
The movie that I work with is much longer (approx. 400 sec). If I use this movie in the “scratch” example it works also.
If I run my sketch, it does not work.
It seems to me, that between movie.play and the movie.jump there needs to be a delay.
I did a little sketch to test this.
If on my system I leave the delay logic (counter) out, it will never jump. With this logic it works (counter>5). This might be dependant on the system performance.

import codeanticode.gsvideo.*;

GSMovie myMovie;
int state;
int counter;
void setup() {
size(640, 480);
background(0);
state=0;
counter=0;
frameRate(10);
// Load and play the video in a loop
myMovie = new GSMovie(this, “C:\\video\\komplettV1.mov”);
myMovie.play();
}

void draw() {
switch (state){
case 0:
counter++;
if (counter>5) { //delay
myMovie.jump(300.0);//mov is >400 sec
state++;
}
break;
case 1:
if (myMovie.available()){
myMovie.read();

image(myMovie,0,0);
}
break;
}

}

Look at the example “Scratch” provided with the library. It shows how to use GSMovie.jump() method. Note that jump() expects a jump point expressed in seconds. Does it work as expected on your system?

Is there a known issue with movie.jump() ?
I cant get it working. It seems that the jump is always to the beginning of the movie, disregarding whatever I define as jump-target.
