mpv-examples - qt_opengl does not work with integrated graphics
My laptop has a discrete graphics card NVIDIA GeForce GTX 960M and an integrated graphics card HD Graphics 530.

Using the example https://github.com/mpv-player/mpv-examples/tree/master/libmpv/qt_opengl,

It works fine under the independent graphics card, but reports an error under the integrated graphics card:

After setting this up, it works fine. qputenv("QT_OPENGL", "software");

#include "TestOpenGL.h"

TestOpenGL::~TestOpenGL()
{
}

void TestOpenGL::initializeGL()
{
    if (!initializeOpenGLFunctions()) {
        qWarning("Failed to initialize OpenGL functions!");
        return;
    }

    QOpenGLContext *context = QOpenGLContext::currentContext();
    if (context) {
        qDebug() << "OpenGL Version:" << context->format().majorVersion() << "." << context->format().minorVersion();

    } else {
        qWarning() << "No OpenGL context available";
    }
}

void TestOpenGL::paintGL()
{
    QOpenGLWidget::paintGL();
}

debug is also ok.
