    it seems symbian provided RTP support in its v9.1 but Nokia has removed it from their S60 3rd edition.

    if thats the case then really bad. Why would Nokia want to do?

    Hi,

    I'm just iinteresting - are you planning to use RTP over TCP (because of NAT)? Or you plan to use it normally over UDP having some other solution? VPN tunnels or public IP addresses for example?

    Hi!
    I've use RTP over UDP with S60 2ndED without problems.
    Now I'm porting my code to 3rdED, but I have some problems....
    - I can't use KUseDefaultIap.
    -I can't see in the mobile phone what it's being streamed.I'm using ethereal in the server side, and I can see that the streaming session has started, but after few seconds the mobile phone sends to the server the command PAUSE and then TEARDOWN.

    Does anybody have this problems too?

    Thanks in advance

    Hi,

    I asked, because I simply don't understand how you send packtes over UDP to the phone??? It's of course possible to stream video from the mobile to the server, but how can be RTCP control packets from server delivered back to the mobile or how you can stream RTP/RTCP packets over UDP in the reverse direction??You must have problem wiht firewall/NAT between public Internet and operator backbone intranet...

    Hi,
    I'm not doing streaming from the mobile to the phone.
    In the mobile phone,if you use RealOnePlayer you can stream from a server. I have developed an application that uses CVideoPlayerUtility::OpenUrlL() to do streaming, and I don't have to worry about sockets or anything else.
    RTP packets runs over UDP and RTSP over TCP when the communication is between the server and the mobile phone. However, when I use my laptop with Quick Time 7 as client, RTP packets are encapsulates in RTSP packets.
    I haven't tried to do streaming in the reverse direction.

    I'm REALLY insterested on using SIP/RTP stack in my product.

    I have seen that Nokia offers SIP plugin. But what about RTP stack support for Series 60 v2?

    How have you included RTP support for S60 v2 in your program.
    Own implementation? 3rd Party? I definitely can't spend a lot of time in implementing my own stack. I need to focus efforts in high level functionality.

    Please share your ideas.

    Thank Your very much!

    Re: Does Symbian Support RTP?

    hi

    I an working on emulator, not using any phone now. Firstly i establish connection using SIP with my video server which then sends me video in rtp payloads (video on demand application). My problem is how do i buffer and playback stream using CVideoPlayerUtility() and openURL(). Because once my server is through with SIP, it immediately starts sending rtp payloads.

    Can you please tell how did you do it or if possible share some portion of your code.

    I will be really thankful.

    hi

    Yes Symbain 9.x support RTP but there is no support for the same in sdk. So either you implement your own RTP stack or you recieve RTP packets over UDP and youself perforn the necessary operations.

    Stenlik, just about all internet routers support replying to UDP packets, even behind a NAT barrier. They create a tunnel for every packet and allow for responses to go in the other direction. This is not an obstacle.
