Re: [Interest] What for does qt5gui need OpenGL?

Why don't you like the dynamic loading solution? I would always prefer it over static linking, if possible. All plugin based systems (even Qt, where platform is a plugin) are based on dynamic code loading. OpenGL should not be a dependency on a base windowing framework imho. On Wed, Nov 6, 2013 a

The scene graph renderer uses the same buffer object for both indices and vertices. This is within spec, but I worried that some drivers might like it less than others. This setup is the first one where it doesn't work. The patch doubles the amount of uploads we do, but the total memory is uncha

Oh, I overlooked the code sample you provided. You should listen to the imageAvailable() signal instead of imageCaptured(). What you get from imageCaptured() is just a preview, it's emitted right after the camera sensor captured the image but at this point the final image is not processed yet.

Re: [Interest] Qt 5.2 scenegraph does not draw anything for our MIPS cpu/VIVANTE GPU platform

I find it very strange that qmlscene without an input file would produce the same apitrace as a qmlscene with a file. The apitrace is a reflection what we try to draw after all and that is highly dependent on what the input is. What does the trace look like? It is a long-shot, but you could try
