    Video Stream Problem

    I try to make video communication between two mobiles based on Ad Hoc newwork.

    Here is my process:
    CamereViewFinderReady->AsynEncode(jpeg)->SynRTPSend
    RTPReceive->AsynDncode(jpeg)->Bitblt

    Now,the program can work in 1 or 2 seconds,then throw out KErrNotFound,and does not display the video any more.

    Can anyone give some advice?

    eng.mohamed your problem is not related to great2328's problem, he was able to get the stram but after some time it was crashing in your case you not even started.

    search in wiki & forum Nokia examples for getting stream from camera.

    try not to hijack somebody else's thread when your problem is not even close to the original steaming problem. try creating a new thread.
