  "message": "RTCP: implement reduced size RTCP for audio\n\nreduced-size RTCP, i.e. not prefixing RTCP packets with either a sender report or receiver report has been implemented for a long time but only for video.\n\nThis CL adds it for audio as well. This reduces the size of audio NACKs (16 bytes, typically one NACK per packet) sent by not prefixing it with a receiver report (32 bytes).\nOther packets are not affected as e.g. transport-cc feedback does not add a RR even though that is technically required.\n\nThe effect on NACK can be tested by running Chromium with\n  --disable-webrtc-encryption --force-fieldtrials\u003dWebRTC-FakeNetworkReceiveConfig/loss_percent:5/\nagainst this fiddle negotiating audio nack:\nhttps://jsfiddle.net/fippo/8ubtLnfx/1/\n\nBUG\u003dwebrtc:340041654\n\nChange-Id: I06fb94742ff1b6f9a464c404bfc53913f23498d8\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/350269\nCommit-Queue: Philipp Hancke \u003cphancke@meta.com\u003e\nReviewed-by: Jakob Ivarsson‎ \u003cjakobi@webrtc.org\u003e\nReviewed-by: Harald Alvestrand \u003chta@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#42330}\n",
