I am new to directfb and I am trying to draw from one screen that has
a primary layer with DSPF_ARGB32 piexel and a second layer that is
DSPF_UYVY. I'm receiving a pixel stream that is yyuv and I can draw
it directly into the primary surface by converting each pixel yuv2rgb
and filling the source. I thought it might be more efficient to load
the data into the second surface but that doesn't show anything even
with the primary surface colour of (0,0,0,0), so now I am stuck trying
to Blit to the primary surface and I haven't been able to find a
combination hat allows me to escape this type of error. I have tried
several DrawingFlags and BlittingFlags so is what I want to do even
possible?
(!) Failed blit config:
Drawing flags:
Blitting flags:
Source blend function: DSBF_SRCALPHA
Destination blend function: DSBF_INVSRCALPHA
Any help would be appreciated.
Martin
