I've got it.

the segmentation fault was due to a "new osg::State", instead of using the GraphicsContext ones.
See line 54 and line 58 of the code attached.

Now that the code works, the RGB texture was compressed to DDS but it is not flipped.

Could be that "osgDB::writeImageFile" use the RGB plugin to write the output instead of the DDS plugin?

Thank you!
