OK, you mean "swapping out" as in offering a new payload type, having that payload type accepted, and then starting to use it for sending, stopping the use of the previous payload type. Like this: offer: PT 74=VP8 answer: PT 74=VP8 (accepted) (offerer sends using VP8) offer: PT 74=VP8, PT75=VP9 answer: PT74=VP8, PT75=VP9, preference=75, 74 (offerer switches to VP9) I think removing PT74 in this case would break stuff, so we shouldn't do it. Note - I think this is JSEP-land. But it's tangential to the rollback question. On whether the rollback can free up content-types: Yes, I think it should. The theory of rollback is that the other guy never saw the offer, so it has no chance to avoid using those PTs. -- GitHub Notification of comment by alvestrand Please view or discuss this issue at https://github.com/w3c/webrtc-pc/issues/2368#issuecomment-558541020 using your GitHub account
