directshow rtsp source filter

i need a directshow filter around the live555 library. this filter should be a source filter that will accept a rtsp url? and or sdp file. and stream out the video stream and the audio stream. i do not need the streams decoded. i already have decoder filters, i simply need a way from within graphedit and windows media player to get the play the streams.? ? basically i need a filter that wraps around the live555 code and will stream out the video stream and audio stream..? also put in registry proper abaility so when you open a url in windows media player rtsp://myserver/[login to view URL] ? ? or open up? the sdp file locally it will play it.? again i already have decoder filters.. i just need the input source filter that will read the rtsp stream and stream it.? ?
