Hi All,
Does DirectFB 1.3.0 onwards support OpenGL ES on TI OMAP 3 over linux
framebuffer without X? Has anyone used this?
I have a Zoom development kit which runs DirectFB on GL ES.
I've used GTK over DirectFB on TI DM6446 and found that the performance
is not that fast. Especially opening windows of D1 size will take in the
order of seconds (1 - 1.5 secs) to open.
If there are just a few widgets, the overhead might be due to some pixel
format conversion. You should check dfbdump and maybe turn on the
"software-warn"
option to get a complete list of operations (except for gdk pixbuf etc. code
that Lock()s a DirectFB surface).
Is there any significant improvement using DirectFB with OpenGL ES on OMAP?
Depends on the complexity of the application or toolkit. Heavy GTK or Qt apps
cannot really take advantage at the moment, but there's some potential for
optimizations (display lists etc).
