[streaming] Streaming to S60 and bypassing NAT/PAT in network

[RG Nur Rahmat]

Hi Guys,

I have experimented streaming from a local server (with local IP) to Nokia
E60 smartphone and its RealPlayer and it has worked fine with respect to
audio and video. However, it failed to work in public IP environment. These
are the steps of what I did:

//test for mpeg4 (176x144) real player (working for WLAN)
vlc.exe -vvv -I dummy "d:\video\empire.mp4" --sout="#transcode{vcodec=mp4v,
vb=128,acodec=mp4a,ab=64,channels=2,audio-asyn,width=176,height=144}:rtp{mp4a,sdp=rtsp://
0.0.0.0:5000/mystream.sdp,ttl=127}" --aspect-ratio=width:height

//type in web browser of E63
rtsp://192.168.168.31:5000/mystream.sdp

And I just changed the IP address (setting lowest and highest port 1024 and
65334 respectively) in E63's web browser to my public IP, with the help of
WireShark, I know that the S60 and server connected, however, they failed in
the handshake/RTSP protocol.

Troubleshooting my public IP for streaming, I used my PC's RealPlayer SP to
play rtsp://stream.zoovision.com/live.sdp, it worked fine. However, it can
only display the title "live" in my E63's Real Player, I suspect that
RealPlayer SP has more flexibility in negotiating port and protocol with the
server.

Therefore, I would like to know what files and things I need to be aware of
in forcing my server to be able to stream in public network?

Thank you very much for your assistance in advance.

Regards,
RG
