[vdr] Re : Bitmap-format of OSD?

[Patrick GUENEAU <pgueneau@wanadoo.fr>]

The main problem with SPU is it is limited to 4 color bitmaps
(2bits/pixel)

You can take a look at spuenc code in MPlayer program. It has been added
by Carl George. 
You can clearly see what kind of bitmaps you can encode.

It seems too that SPU size may not be too large (whole screen size as in
DVB OSD) ; at least, there are problems with em8300 linux drivers ;
actually, SPU wasn't designed to implement anything else than subtitles
where 4 colors is enough.

Maybe you can have a look at how Marcus (Metzler) started to implement
DVBAPI for DXR3 cards using SPU code.
