How to display camera frame using QOpenGLWidget



  • Hello,

    I am having Qt and Opengl ES2.0 Embedded application. I am using camera to detect face and eye and display it on central widget. To make processing better I have used opengl es2.0 but I am getting few errors for opengl functions.

    Below functions are not supported in QOpenGLWidget class.

    1. updateGL()
    2. glOrtho()
    3. glRasterPos2i()
    4. glDrawPixels()
    5. convertToGLFormat()

    Is there any way to integrate equivalent functions of above all using QOpenGLWidget class. If yes then let me know I will appreciate your help. Thanks in advance.
