Why? RTP has nothing to do with mp4 file muxing. If you can stream to  
VLC, you should be able to stream to QuickTime.
That is:

1 as long as you don't use any of the h.264 codec options that QT  
doesn't support (QT doesn't support H264 very well)
2 you write the SPS/PPS to the SDP file
3 you only use 1 slice (at least i haven't been able to use more than  
1 slice when doing VLC h264 RTSP to quicktime. If someone figures out  
why, i'm all ears).

Then you'll just have to look around very hard for someone who  
accidently left them somewhere, or pay up the fee that is required to  
read/use this standard.

See above.
