I have a MPEG4 RTSP stream from a networked camera manufactured by AXIS. I need to write a video file of some kind from this stream. I want to use the stream as-is if possible, as I need to handle several dozen cameras at once.
I've already tried 3ivx's media muxer/splitter, and it can create a file which plays back in VLC, but their splitter crashes if I try to play it back via DirectShow. This happens with several different MP4 decoders in line after it, so I don't think it's the decoder's fault.

Could someone point me in the right direction?
Thanks.
