Hello, 

When rendering a simple jpg, sometimes I was getting this message:

(!!!)  *** WARNING [slow JPEG decode path] *** 
[/home/microtrol/SetTopBox/stapi/A30-MT/apilib/src/st2fx_Andreza/src/DirectFB-1.4.3/source/interfaces/IDirectFBImageProvider/idirectfbimageprovider_jpeg.c:953
 in IDirectFBImageProvider_JPEG_RenderTo()]

As I was also having some problems with fb device (stgfb) I increased 
it on module insertion (from 10 Mb to 20 Mb) and now the message
is gone.

I guess the WARNING means: 'I can't decoded jpeg by hardware so I will
try by software'. Right?

My question are:

1. Does the slow decode path means libjpeg usage? Or does it
always decode through libjpeg?

2. Why does the WARNING dissapear with a larger fb video memory?

3. I noticed ilixi is using DSCAPS_SYSTEMONLY for surface allocation when 
rendering a jpeg. Why? Can someone explain me the exact difference between 
system and video memory. Is fb memory equal to video memory?

Any explanation on jpeg decoding would be very appreciated.

Thanks,
Ezequiel.
