I somewhat disagree. The Unix philosphy doesn't apply very well to 
multimedia. When you have to control things like AV sync, speed, decoding, 
encoding, extra params (like, quantizer of image for pp), tight integration 
of components within a single binary is manditory. Not to mention the 
example you gave above will just be slow as hell..
