Debug build still did not provide a nice backtrace, but I've followed the
crash to
void TextureRectangle::applyTexImage_subload in TextureRectangle.cpp
At the line:
dataPtr = reinterpret_cast<unsigned
char*>(pbo->getOffset(image->getBufferIndex()));
dataPtr gets assigned 0 and then the glTexSubImage2D call generates the
segfault.
It's normal for pbo->getOffset() to return a 0, and correct to pass
this to glTexSubImage2D, but only if a PBO is bound, if it isn't then
it will result in a seg fault. Perhaps there is some mistake in the
code that isn't binding the PBO when it should.
OK, I'll try to check this too.
Do you get a crash if you use the --texture2D on the osgmovie command line?
No, it runs, but with
Warning: detected OpenGL error 'invalid enumerant' after RenderBin::draw(,)
after every frame.
