I'm not sure I understand your question, but if you have an input source 
that delivers 30 fps, but you want, instead to deliver 15 fps, then just 
modify your input source's "doGetNextFrame()" function so that it discards 
every second frame.

This assumes, of course, that your input source is not encoded in a format 
(such as MPEG-1, 2 or 4) that uses P (or B) frames.  But you didn't say 
what input format you are using....
