Hi,

I’m building a video player based on GlVideo (Ubunut Linux 16.04 Processing 3.4) and I encounter a problem with the video.jump(float) function. The video seems to strangely fall down to fixed positions (8,3s, 16,6s, 24,9s, etc…) depending on the duration of the file.  
My code was a bit tricky with ControlP5 progress bars and stuff and to remove any interference, here a simple code based on single video example that shows the same problem :

```auto
import gohai.glvideo.*;
GLMovie video;

void setup() {
  size(320, 240, P2D);
  video = new GLMovie(this, "launch1.mp4");
  video.loop();
}

void draw() {
  background(0);
  println (video.time());
  if (video.available()) {
    video.read();
  }
  image(video, 0, 0, width, height);
}

void mousePressed() {
  video.jump(14.0);
}

```

This code results in a jump to 9.8765335 instead of 14.0…  
If I use `video.jump(11.0);` It’s the same… Jumps to 9.8765335

But If I use values under 9.0, the jump works perfectly well…

If anyone could explain this limitation, I would be glad!  
Thanks by advance,

Fabrice.
