Hi all,
I am working on DirectFB in a product.
We currently allow the user to change from PAL-NTSC via the SetEncoderConfig
function.
When this change takes place we change all of the Display Layer properties
to the new resolution
(720*576).
This is done internally ie from within our SetConfig function of our Enoder
driver.
This works fine. However, all of the surfaces that are created on the
display layers still think that they are 720*576 not 720*480. This means
that when they start to draw we get an out of range error.
What are other people doing when they change to NTSC?
Is there a way to change all of the Display layers AND surfaces internally
from our driver?
If we do this how will this effect an application using the library as they
to need to be informed of Surface changes.
Is the preferred method to change all of the Display layers internally and
inform users of DirectFB on our hardware that after a call to
SetEncoderConfig(NTSC) that they have to release, and create all surfaces or
is there a better way?
Hope you can help
Cheers
Dan
