I think it might be better to keep libsoftmpeg purely as an mpeg decoder. It
could then have different 'frontends' for input - such as VDR, file, DVB
etc.

Hmm - I now want to try it out to see what will happen! :-)

I've been struggling getting the OSD to work. If I create some rectangles on
the primary surface everything is fine - I get alpha blended rectangles.

I created a simple window, and this is displayed. However, as soon as I call
'GetDisplayLayer' in 'manage_directfb_stuff' then no windows are displayed.
This seems to be why I'm not getting an OSD.

Likewise, in my test program windows did not work if DLSCL_FULLSCREEN was
set. I'm going to have to delve within DirectFB to see what is going wrong -
Erk!

Thanks,

Colin
