How do LAV filters decode realmedia??

[jamesN]

Do LAV filters provide the best playback for realmedia files, and how do they decode it??
I know that libavcodec can decode realvideo and cook, but they are still buggy. So, do LAV filters use realmedia splitters and decoders to do that?
cheers,

lav, as its name implies, only uses libav afaik
