EGL + QQuickFramebufferObject on Jetson TX1 .. EGL_BAD_ALLOC (0x3003) problem

[Bodo]

Hi all,

I got an EGL stream running 'with' an QQuickItem.
Now I like to not have it fullscreen only, but be able to use it within QML-based GUI (render it to a dedicated area, maybe transform it or add border or such).

I started of with the 'textureingsnode' example of the qtdeclarative package.

But now I'm stuck in the early initialization phase when trying to create the window surface.
My code:

m_display = (EGLDisplay*)eglGetDisplay(EGL_DEFAULT_DISPLAY);

Display* disp = QX11Info::display();
m_window = DefaultRootWindow(disp);

// m_config is found by iterating the configs and does return the same chosen config as before without using fbo

// m_display and m_window have non-NULL values here
m_surface = eglCreateWindowSurface(m_display, m_config, m_window, NULL);
//-> results in eglError 12291 (3003, EGL_BAD_ALLOC)

Did anyone try something similar?
Any hints are appreciated.

Thanks + Best,
Bodo
