    MMAPI fails to create player with RTP

    Hi,
    I am developing a PTT application. i need to carry out real time voice transmission. I used my system as voice transmitter, developed a transmitter using JMF and started a RTP session and my mobile application as receiver.
    In the mobile appl when i tried to create the player using

    Manager.createPlayer("rtp://172.17.85.22:200004/audio");

    It resulted in javax.microedition.media.MediaException: Player cannot be created for rtp://172.17.85.22:20004/audio

    Can any one suggest me how to do real time voice transmission with MMAPI. Plz send me links of code samples using MMAPI with rtp.

    Hari,
    Previously me too was reading about RTP in MMAPI. And I remember this lines from the link
    "On Nokia devices, the MMAPI player always downloads the remote media file completely before the playback is started. The real-time data streaming protocol (i.e, the rtp://host style URL locator) is not supported."
    http://www.awprofessional.com/articl...?p=375708&rl=1

    Not sure how far this is applicable for the latest devices.
    Read here that "S60 3.0 will support RTSP streaming."

    May be this link is of some interest too.

    hi Dhanya,

    which platform you want to target?
    There are two protocols with streaming support now (rtp/http) but available only on newest devices and only on real device for tests,
    see similiar topics:
