libwebrtc will stop sending SDES headers after the first receiver report on a SSRC. This breaks probing if the receiver report is sent before probing is completed. This change delays receiver reports for a SSRC until the first non-probe packet is received.

Any updates on this? I'm happy to make changes if there are other ideas on how to propagate the probe status into the interceptor! |

libwebrtc will stop sending SDES headers after the first receiver report on an SSRC1. This breaks simulcast probing if the receiver report is sent before probing is completed. This change delays receiver reports for probing SSRCs until the first non-probe packet is received.
I didn't find any easy way to get this information into the interceptor, so I opted for using attributes. Let me know if you prefer some other means.
