VDR provides an easy to use plugin interface that allows additional functionality
to be added to the program by implementing a dynamically loadable library file.

The OSD provider object is allocated on the heap and shall not be deleted

provider, or when the program ends).
<p>
Note that an OSD implementation need not be physically linked to the device
in any way. All it needs to make sure is that the OSD will be visible to the
user - whether this goes through OSD facilities of the physical device (like
a "full featured" DVB card) or through a graphics adapter that overlays its
output with the video signal, doesn't matter.
