Generally, the components of WebRTC service are classified into Signaling Server and WebRTC client. The HW encoder we used supported updating only bitrates on the fly and that worked fine with WebRTC. All current implementations seem to support VP8 (correct?), but I guess the MPEGLA has blocked its standardization. 264? The answer isn't a simple one. More recently, we've also seen discussions around. I would expect that when you ingest webrtc in H264, that could be used without transcoding for HLS.

Current WebRTC implementations use Opus and VP8 codecs: The Opus codec is used for audio and supports constant and variable bitrate encoding and requires 6-510 Kbit/s of bandwidth. This VP8 encoding support now complements the MPEG-2 and H. The plan is to use the OpenH264 (same lib as Firefox uses) for encoding and FFmpeg (which is already used elsewhere in Chrome) for decoding. 264/AVC codec sometime in the next few months. 264/AVC using Constrained Baseline Profile Level 1.
