[warning] ofGstVideoUtils: update(): ofGstVideoUtils not loaded - Linux Ubuntu 16.04LTS

Hello,

I continue to have this problem:

[warning] ofGstVideoUtils: update(): ofGstVideoUtils not loaded

i already reinstall install_codecs.sh and install_dependencies.sh but nothing happen, any suggestion?

thanks in advance for the help

this is a very generic problem that means that something else is wrong can you post a little bit more about what you are doing? loading a video, using a camera? also if there’s any other output in the console?

It is a simple software to control two videos, follow the code:

[code] #include “ofApp.h”
int currentVideo = -1;

//--------------------------------------------------------------
void ofApp::setup(){

ofSetFrameRate(30);
videos[0].load("loop1.mp4");
videos[1].load("loop2.mp4");

ofBackground(255,255,255);

}

//--------------------------------------------------------------
void ofApp::update(){
videos[0].update();
videos[1].update();

std::stringstream strm;
strm<< "fps:" <<ofGetFrameRate();
ofSetWindowTitle(strm.str());

}

//--------------------------------------------------------------
void ofApp::draw(){

videos[0].draw(0,0);
 videos[1].draw(0,0);

}

//--------------------------------------------------------------
void ofApp::keyPressed(int key){
if(currentVideo == key)
return;
currentVideo = key;
switch (key) {
case ‘k’:
videos[1].stop();
videos[1].close();
videos[0].load(“loop1.mp4”);
videos[0].play();

        break;
    case 'j':
       
    videos[0].stop();
     videos[0].close();
        videos[1].load("loop2.mp4");
        videos[1].play();
        break;
    default:
        break;
}

} [/code]

Also i give one screenshot about the warning:

Thanks

does the video player example that comes with OF work?

So,

I try the videoplayer example and follow the result:

When i run and close:

My application resolution is 2560X1080, maybe is it the problem?

Maybe a mistake in ofApp?

[code]#pragma once

#include “ofMain.h”

class ofApp : public ofBaseApp{

public:
void setup();
void update();
void draw();

void keyPressed(int key);
void keyReleased(int key);
void mouseMoved(int x, int y );
void mouseDragged(int x, int y, int button);
void mousePressed(int x, int y, int button);
void mouseReleased(int x, int y, int button);
void mouseEntered(int x, int y);
void mouseExited(int x, int y);
void windowResized(int w, int h);
void dragEvent(ofDragInfo dragInfo);
void gotMessage(ofMessage msg);

ofVideoPlayer videos[2];

}; [/code]

Thanks :slight_smile:

So, i modified the example and when i load my videos it give me again the “warning” also with a fullhd mp4.

I tried to use a mov in photojpeg, again the same warning but the video was more smooth.

The cpu run at max 60%. [the machine is zotac ci323 with 8gb Ram and SSD]

My videos are 2560X1080, Is there any kind of suggest about the codec (i tried .mp4 H264 and .mov Photo-Jpeg)

Also another problem is the audio part -> it is very low

Can i try to change the OS with a different version of ubuntu? Any suggestion are more than welcome

Thanks for your help
