Inaki has brought up a situation where the existing routing rules in Section 8.3 do not appear to work correctly.
In the current spec, if parameters.encodings[i].ssrc is set for some value of i, then pt_table entries are not added.
However, if "rtx" is included in codecs[] but parameters.encodings[i].rtx.ssrc is not set for all values of i, then RTX packets could be dropped.
Similarly, if "flexfec" or "red" is included in codecs[] but parameters.encodings[i].fec.ssrc is not set for all values of i, then FEC packets could be dropped.
Do people agree that this represents a malfunction?
