    Usually you'll only want to stream one audio track to a client.

    Out of curiosity, what use case is there for two audio tracks in one stream? Maybe there is a different solution we can suggest.

    You can use the link Richard posted and the client can choose the language when they play the stream.

    Does it make sense to send two video streams if the user can only watch one at a time? Doesn't really make sense to send two audio streams either. You will be paying for the bandwidth for an audio stream the client is not using.

    You can set up your flash client to switch to the other stream/language when they press a button.

    Understand it like this: the request starts with the client, then server streams the requested track. The server does not send multiple tracks for the client to sort out.
