Running individual codecs in distinct processes is feasible, but it will 
incur a huge memory copy penalty.

Running demuxers in separate processes is more difficult owing to the 
large number of things demuxers can do (vlc:// and playlist parsers are 
probably the worst ones in that regard). Again, this would incur memory 
copying from the access and to the codecs.

Running the entire decoding pipeline in a separate process would be 
trivial from the LibVLC perspective - if LibVLC actually worked 
properly. But we still have the unmaintainable and broken playlist code  
there. Worse, you need to rewrite the UI from scratch. And by the way, 
on Linux, most VLC crashes are caused by the user interface (or the 
crappy LibVLC media/player code if you use LibVLC).
