[vdr] Re: DVB subtitling

[Dave Chapman <dave@dchapman.com>]

Ja,

I started such a project (dvbsubs) a while ago.  I got as far as 
displaying something on the DVB card's OSD, but there is still lots of 
work to do.

It also dumps an XML representation of the subtitle stream to stdout at 
the same time as it decodes it - this could be very useful when you are 
trying to understand the specification.

It's in CVS at http://sourceforge.net/projects/dvbtools/ - follow the 
"CVS" link for instructions on accessing sourceforge CVS repositories.

At the moment it writes the data direct to the DVB card's OSD.  A useful 
first step at improving this code would be to use a graphics library 
such as libpng to save the bitmaps to files.  This will aid debugging a 
lot as well as enabling the subtitles to be converted to DVD format 
(another eventual aim of mine).

Contact me off-list if you want any help.

Regards,

Dave.
