The FMT 15 is not specific only to REMB or loss notification messages. Rather, it is the Application Layer FB (AFB) of Psfb (Payload Specific Feedback Messages). See https://tools.ietf.org/html/rfc4585#section-6.3 TBR=terelius@webrtc.org Bug: webrtc:10336 Change-Id: I8cd27ef9ee044bf7b7e7c1bd1a53c1dae2d95006 Reviewed-on: https://webrtc-review.googlesource.com/c/123886 Commit-Queue: Elad Alon <eladalon@webrtc.org> Reviewed-by: Danil Chapovalov <danilchap@webrtc.org> Cr-Commit-Position: refs/heads/master@{#26827}
