Hi,

We are testing IP Multicast, with Flahs media player 4.0.

We set up the encoder and generated the manifest file.

Multicast start, but we see lot of bufferring and video running fast.

After about 2 minutes, the encode stops publishing to the server.


We are using digital rapids as the encoder.

Any idea this might be causing ?

    Do you see any errors in FMS logs - core,edge or master logs.

    No Error on the FMS server.

    I tried with FMLE today.

    The encoding starts and stays up fine,

    i can see the clients related to multicast in FMS admin.

    When i start the player, it just says "Waiting for the video"

    A few things to try:

    1. If you're using the 'multicast' application that ships with FMS4, it logs state transitions and event info to the app log as the server-side multicast relay (a server-side NetConnection/NetGroup/NetStream) start up and redirect the ingest stream from FMLE into the Flash Group. I'd recommend reading through that and verifying that the server-side objects handling the relay into the Group are happy (i.e. not disconnecting or being closed down).

    2. The multicastplayer client SWF app has some flashvars defined in the HTML shim file that loads it. One of these is a debug flag. If you set that to true, you'll get some debug info surfaced up to your UI. This will include the various events the client is processing on its NetConnection/NetGroup/NetStream that's being used to play the multicast stream out of the target Flash Group. Feel free to post those details back to this thread.

    3. If you're doing IP multicast, that won't work over the public internet. In that case you'll want to be using P2P multicast.

    Best,
    Seth
