Re: [AVT] The RTP payload format for multichannel codecs's signalling problem

Hi Tom,

The problem you describe has what I understand solely to do with what 
you use a established media stream. However the problem I discuss has to 
do more directly with the codecs capabilities. If a encoder has stereo 
and mono capabilities and can switch between them, what is necessary to 
signal. For my problem there are certain configuration information that 
needs to be distributed outside of the encoder to decoder chain, this 
primarily being the receivers playback facilities, so that they are 
capable of handling both outputs from the decoder.

So I don't think the problems are that similar. My problem is in direct 
relation to properties of the codec, while your problem is in relation 
the usage.

Cheers

Magnus
