[Live-devel] Windows vs Linux RTSP/RTP/UDP difference

Hello All,
I am facing a bizarre platform dependent problem in streaming real time 
Mpeg 4 (Standard and High Definition).

I have an embedded linux where I capture a live video and convert it 
into MPEG4 frames (using a hardware encoder). I use 
MPEG4DiscreteStreamFramer to stream these frames using modified 
testOnDemandRTSP example.
I have almost negligible latency when my client (mplayer) runs on a 
linux platform. But the same sources (at least rtp relevant part) when 
compiled on windows using mingw shows a huge latency of about 2 to 2.5 sec.

Has anyone else faced these problems before ? Are they related to lower 
level protocol implementation ? Any suggestion would of great help.
