 From my experience that's a rather bad idea. A while ago I had to  
debug/fix at least two different MJPEG decoders because they didn't like  
the pictures that one particular camera provided. JPEG decoding can be  
simple but if you want a complete version it's far from trivial. A quick  
look at libjpeg should give you an idea.

That being said, if you only need it for a quick hack, you could have a  
look at luvcview or Ekiga. They both have their own JPEG decoders built-in.

Cheers,
Martin
