Streaming to vlc

Wed Aug 22 02:52:36 PDT 2012

Thanks Emile,

Yes it is working over network on VLC player now. Though there is a delay.
Any answers to that? Kartik do you have any delay in your video. How did
you fix it?

Also, since it is working on VLC now over network. Thats not my final aim.
What I am looking at is to capture the buffer, decode it  and pass the
frames across to another application. Any idea as to how will I capture the
incoming RTP buffer on windows?

Thanks,
Mazahir
