QT5 eglfs - eglError

Other Parts Discussed in Thread: TSC2007

Hi Prabindh,

Can you help me with this?

I am using QT 5.0.1, the hellogl_es2 example run but it is at 58 fps - when using qt4 on the same hardware and drivers i was able to get to 100 fps. Below is the console message and error ... Thanks a bunch, Johny.

./hellogl_es2 -platform eglfs

Hi,

There are some possible reasons for the lower frame rate performance with the qt5 version.

1) Are both compared versions compiled similarly? Are you using the OpenGL ES acceleration by SGX in both qt versions? There are two links to tutorials about:

http://processors.wiki.ti.com/index.php/Building_Qt

http://processors.wiki.ti.com/index.php/Building_Qt_with_OpenGL_ES_accelerated_by_SGX

Are you follow the same tutorial or some else? If yes post a link to it.

2) The default version of qt coming with the dvsdk 4.03.00.06 is Qt version 4.6.3. It should be has some optimizations.

3) It should be useful to start a discussion about performance issue in the http://qt-project.org/ forum.
