[vdr] Softdevice + DirectFB + cle266 : one step beyond

[Nicolas Huillard <nhuillard@ghs.fr>]

I fianlly got and image (moving) and the sound : quite jerky, with a lot 
of drops and missed squares on the screen.
STDOUT is like this :


ac-tex damaged at 30 34

slice missmatch
invalid mb type in B Frame at 1 17
slice missmatch
invalid mb type in B Frame at 3 19

... and /var/log/message shows :

There is also errors on channel switch :


Jun 10 22:53:52 vdr vdr[1885]: ERROR: thread 1885 won't end (waited 3 
seconds) - cancelling it...


Then, after a few minutes :


invalid mb type in B Frame at 18 16

mb incr damaged

I'll try thread patches.
Setting LD_ASSUME_KERNEL=2.4.1 before running vdr does not improve 
anything : I get the blue screen with no video / no sound.


I still don't have OSD, though. I'll try some other tweaks in the code.

What I did to make softdevice work :
* clear CMOS with the jumper
* reset BIOS setting to "optimzed defaults", and redo my settings (boot 
device, activated devices, etc.
* (I hope those where not the culprit)
* recompile softdevice with the following change :
	in void cDFBVideoOut::SetParams(int newXres, int newYres)
	change the value of dlc.options =
	from (DFBDisplayLayerOptions)( DLOP_ALPHACHANNEL )
	to (DFBDisplayLayerOptions)( DLOP_NONE )
* that might not be optimal, but it shows something...


Question 1 : what should I do from there ?
Question 2 : am I the only one who use softdevice / DirectFB on an EPIA 
M10000 ?
