Sorry this code is pretty rough, as I said I am just learning but I am
hope you can make sense of it.
{
DFBCHECK(DirectFBInit( &argc, &argv ));
DFBCHECK(DirectFBCreate( &dfb ));
dfb->SetCooperativeLevel(dfb, DFSCL_FULLSCREEN);
DFBCHECK(dfb->GetDisplayLayer( dfb, DLID_PRIMARY, &layer ));
layer->GetConfiguration (layer, &layer_config);
memset( &dsc, 0, sizeof(DFBSurfaceDescription) );
dsc.flags = DSDESC_CAPS|DSDESC_WIDTH|DSDESC_HEIGHT;
dsc.width = layer_config.width;
dsc.height = layer_config.height;
dsc.caps = DSCAPS_PRIMARY;
DFBCHECK(dfb->CreateSurface(dfb, &dsc, &primary ));
DFBCHECK(dfb->GetDisplayLayer( dfb, 1, &layer1 ));
DFBCHECK(layer1->SetCooperativeLevel(layer1, DLSCL_EXCLUSIVE));
DFBCHECK(layer1->GetSurface(layer1, &second));
memset( &dsc, 0, sizeof(DFBSurfaceDescription) );
layer1->GetConfiguration (layer1, &layer_config);
dsc.flags = DSDESC_CAPS|DSDESC_PIXELFORMAT|DSDESC_WIDTH|DSDESC_HEIGHT;
dsc.width = layer_config.width;
dsc.height = layer_config.height;
dsc.caps = DSCAPS_NONE;
dsc.pixelformat = DSPF_UYVY;
DFBCHECK(dfb->CreateSurface(dfb, &dsc, &second ));
primary->Clear(primary,0,0,0,0);
// no display
u16 *dst;
if (second->Lock(second, DSLF_WRITE, (void**)(&dst), &pitch) ==DFB_OK) {
int i,j;
unsigned char y0,y1,u,v;
unsigned char *ptr1 = buf1;
unsigned char *ptr2 = buf2;
for (i=0;i<h;i++) {
for (j=0;j<pitch/2;j+=2) {
y0 = *ptr1++;
y1 = *ptr1++;
u = *ptr2++;
v = *ptr2++;
*(dst+j) = PIXEL_UYVY(y0,u,v);
*(dst+j+1) = PIXEL_UYVY(y1,u,v);
}
dst += pitch ;
}
second->Unlock (second);
primary->Blit(primary,second,NULL,0,0);
}
}
working on the primary only this works
{
// this works
char *dst;
if (primary->Lock(primary, DSLF_WRITE, (void**)(&dst), &pitch)
==DFB_OK) {
int i,j;
unsigned char y1,y2,u,v,r,g,b;

for (i=0;i<h;i++) {

y1 = *ptr1++;
u = *ptr2++;

yuv2rgb(y0,u,v, &r, &g, &b);
*(dst+j) = b;

*(dst+j+3) = 0xff;
yuv2rgb(y1,u,v, &r, &g, &b);
