  5. I have the same issue as Dima. It works on my local machine, but not when I upload it to the server.

  10. Hi Tom,
    great tutorial, quick question:
    You transfer the video by using getCamera on the sending site and attachNetStream on a Video object on the receiving side. But what about audio?
    I managed to get the audio input via Microphone.getMicrophone() and I am sending it over the same NetStream as the video. But how do I handle the audio on the receiving side?
    Many thanks,
    Stef

  11. I am one step closer to adding audio to the video chat as well.
    You just have to capture the mic on the receiving side and attach it to the netstream.
    On the receiving side, you just play the netstream, no further actions necessary.

    There is one weird problem though:
    If I set up a connection between a sending and a receiving side, there is no problem as long as I keep complete quiet. But the moment I make a sound, the flash player and/or browser on the receiving side crashes. I googled the problem and it has been replicated but I haven’t come across a solution yet. Any help?

    Project is done in Flash CS5, compiled for player 10 and played in a browser with flash player 10.1. Crashes as well on Mac/safari as on PC/Explorer.

    Weird…

  12. Any idea on how can I stream a file(doc and video) instead live camera?

    Comment by Cristian Rusu — October 19, 2010 @ 8:56 am

  13. Do I need a server for these two scripts to work? I’m trying to stream video via Flash 10.1 in a P2P fashion.

    When I run these files on my Eclipse Flex Compiler, I get NetConnection.Connect.Success but nothing after that.

    Any help is appreciated.

  16. MORTEL !

    J’en ai cherché des solutions de diffusion à grande échelle, mais là, quelle claque, c’est exactement ce qu’il me fallait.

    C’est très simple à mettre en œuvre, alors que le côté technique peut paraître complexe au premier abord.

    Merci pour ce génial tutoriel, et bonne continuation.

  17. i am still putting my head arround this. i am developing apps with live video streaming, which as i am doing it know demands me to have N times de upload bandwith for N stream clients. Can this lower my server load by making the client a receiver and at same time publisher of that stream?
