Right.

That depends on the file.  Piave has a plugin architecture and what 
information is provided for a specific file is completely in the 
responsebility of the plugin. In principle you can't expect anything, not 
even on the number of frames, since something like SVG doesn't have frames. 
The only thing that is certain, is that piave provides a certain number of 
<key>--<value> pairs describing the stream/file.

The communication with the renderer is handled by krender.{h,cpp}
The communication is asynchron, i.e. there is one method emitting the request 
to piave (e.g. KRender::getFileProperties) and another set of handlers to 
parse the XML reply from piave ( KRender::reply_getFileProperties_XXXXX ).

We (Jason and myself) thought about the different parts of the prokoll of 
communication for quite a while.  However, it usually turnes out, that in the 
we need to change things when we really used certain parts of the protokoll.  
So in the likely case that you find some things that don't work or don't make 
sense, let us know.

Cheers, Rolf
