There has been a question of whether in WebRTC 1.0 (and in ORTC), there are multiple entries for "rtx" in RTCRtpCapabilities.codecs[] and RTCRtpParameters.codecs[].

As the WebRTC 1.0 specification currently exists, I believe the answer is "no" for capabilities, but "yes" for parameters, where there is an "rtx" entry for each media codec that can be retransmitted.

In ORTC, I believe the answer is "yes" for both capabilities and parameters.
