IMHO, the one technology that has the best chance of winning out in this realm is WebRTC, esp. as it will be delivered to a huge amount of machines by Firefox and Chrome (I guess Chromium as well)...

Yes, we can definitely do that in the RTP payloader/depayloader. We have significantly more complicated payloaders for other common formats like H.264 and JPEG. It probably also maybe makes sense to...

Actually, it makes everyone life much easier if you entirely avoid stream description the SDP, and put all of that in the RTP header. That said, the current draft is widely implemented enough that you...
