I'm interested in a library that would allow me to take incoming TIFF images and compress them into a more compact 
format, such as JPEG, before writing them to disk.

I've heard of ffmpeg in the past, but as far as I understand those libraries aren't supported on QNX. I've also heard of
 Multimedia Framework TDK. I read the overview document (at http://www.qnx.dk/developers/docs/6.3.2/photon/multimedia2/
overview.html), but I was wondering if anyone could add more basic information regarding this framework: is it included 
with QNX, is it bought separately, does it allow for image compression (especially TIFF to JPEG) in addition to audio/
video?

Any information either regarding the Multimedia Framework or other possible solutions will be much appreciated.
