QFSFileEngine::open: No file name specified

Pixy Software
#1

Hi, all:

  • Windows 10 OK
    I successfully installed PixyMon under Windows 10, and it runs successfully, please refer to !http://www.visionopen.com/images/pixymon.png! .

  • Ubuntu 16.04.1 Fail
    However, after I boot into Ubuntu 16.04.1, with a successfully installed Qt 5.7.1, CMUcam5 Pixy failed to start with the ERROR message:
    QFSFileEngine::open: No file name specified

I successfully load …/CMUcam5/pixy/build/pixymon/src/host/pixymon/pixymon.pro using qt-creator.
however, I’ve got NO idea where I should investigate into for this “QFSFileEngine::open: No file name specified”

Can anybody help?

Cheers
Pei

Hello Pei,
That message is more of a warning and is likely not to cause any real harm. Are you committed to Qt 5.7? Have you tried Qt 5.2 or 4.8?

I’m NOW building/running PixyMon against Qt 5.8 … Still failed…

The ERROR message “QFSFileEngine::open: No file name specified” issue can be corrected by modifying line 41 in file renderer.cpp as follows:

@//Renderer::Renderer(VideoWidget *video, Interpreter *interpreter) : MonModule(interpreter), m_background(0, 0)
Renderer::Renderer(VideoWidget *video, Interpreter *interpreter) : MonModule(interpreter), m_background(0, 0, QImage::Format_RGB888)@

However, still NO captured video under Ubuntu 16.04.2 so far.

Cheers
