[vdr] Softdevice 0.0.7pre2 crash w/ DFB, CLE266

[Nicolas Huillard <nhuillard@ghs.fr>]

Hello,

I'm back from holidays and have tried to test the brand new softdevice 
release, with no luck...
This is an exception thrown in cDFBVideoOut::SetParams() by a call to 
videoLayer->SetScreenLocation()

I added a few lines to get more info :

The interesting bit : "Caught: 
action=IDirectFBDisplayLayer::SetScreenLocation(float, float, float, 
float), result=Invalid area present!"


I tried to not call videoLayer->SetScreenLocation() (with the "if (0)") 
but it just crashes a few lines after that.

I also tried different contents for /etc/directfbrc :
fbdev=/dev/fb0
#mode=720x576
#depth=32
#pixelformat=AiRGB
#pixelformat=ARGB
#sync
disable-module=keyboard
disable-module=lirc
disable-module=cle266


Versions :
* vdr 1.3.11
* softdevice 0.0.7pre2
* directfb 0.9.21 from CVS 20040622 (applied the epia patch attached to 
the pre1 release mail)
* fusionsound + dfb++ 0.9.21 from CVS 20040616
* ffmpeg 0.4.8
* kernel 2.4.26-epia2
* Debian "testing"
* EPIA M 10000 mobo, Skystar2 budget DVB-S


TIA all.

As a side note : which of the output method is the most tested/stable ? 
I don't  really wan't to test Xv (no X on that box), but is Vidix ready 
and less subject to tweaks than DFB? (I tried FB, but the CPU is not 
strong enough).
