[directfb-users] "Invalid area present!" while calling IDirectFBDisplayLayer::SetScreenLocation(in softdevice)

[Nicolas Huillard <nhuillard@ghs.fr>]

In the current softdevice VDR plugin (0.0.7pre2), with an EPIA M 10000 
(CLE266), using the following DirectFB driver :

(*) DirectFB/Graphics: VIA/S3G UniChrome 0.4 (-)

...with the following layer :

    desc = videoLayer->GetDescription();
    fprintf(stderr,"[dfb] Using this layer for Video out: %s\n", 
desc.name);

[dfb] Using this layer for Video out: VIA Unichrome Video

...I have an exception when calling SetScreenLocation() :

          try
          {
          fprintf(stderr,"videoLayer->SetScreenLocation(%f, %f, %f, %f)",
                                        (float) lxoff / (float) dwidth,
                                        (float) lyoff / (float) dheight,
                                        (float) lwidth / (float) dwidth,
                                        (float) lheight / (float) dheight);
          videoLayer->SetScreenLocation((float) lxoff / (float) dwidth,
                                        (float) lyoff / (float) dheight,
                                        (float) lwidth / (float) dwidth,
                                        (float) lheight / (float) dheight);
          }
          catch (DFBException *ex)
          {
            fprintf(stderr,"Caught: action=%s, result=%s", 
ex->GetAction(), ex->GetResult());
            exit(1);
          }


The calling values are as follows :

videoLayer->SetScreenLocation(0.000000, 0.000000, 1.000000, 1.000000)
Caught: action=IDirectFBDisplayLayer::SetScreenLocation(float, float, 
float, float), result=Invalid area present!


The documentation says that "the whole screen is 0.0, 0.0, -1.0, 1.0." 
(notice the negative width)
(http://www.directfb.org/documentation/DirectFB_Reference/IDirectFBDisplayLayer_SetScreenLocation.html), 
but Stephan Lucke has this same code working.
I tested with a -1.0000 witdth value, with no luck (same exception).


Versions :
* vdr 1.3.11
* softdevice 0.0.7pre2
* directfb 0.9.21 from CVS 20040622 (applied the epia patch attached to
