[rtcweb] Video Codec - Possible to use.

["Hutton, Andrew" <[e-mail]>]

Hi,

The question of whether it will be possible for a webrtc application to make us of video codec's (or audio codec) which are not implemented in the browser itself has been raised before but I don't think there has been a clear answer.

Some clarity on this might help some of us to come to a conclusion on where we stand in the MTI debate.

I looked through the archives and found some statements that indicate this should be possible but I not sure we have a definitive statement on this. For example:

Is this really a goal we have agreement on? There does not seem to specific requirements in the requirements draft.

Also I think there are SDP implications relating to this. How would the browser and/or application be able to build the correct SDP to offer additional codecs?
