Youenn, for some reason I can't reply to your comment. > It would be good to rephrase the use of the new slots like the other slots in terms of "Constrain the configuration of |recorder| to encode".... Tried to do this. > In macOS and iOS, when setting both values, I think the min is used (I'll check) but the spec is asking for the max. The rationale for this spec text is what I discussed with Harald earlier: "The rationale is to support variable-rate sources where you get low per-frame quality (QP) in stretches where FPS is low with a pure time-based control, since the ratio of keyframes (in which quality is lower) to delta frames (in which quality is enhanced) would be higher in the low FPS stretches. See also earlier comment in https://github.com/w3c/mediacapture-record/pull/216#issuecomment-1415989756" I realize Apple may not currently be using those rules, but on the other hand the spec includes Apple's implementation by "If neither of the slots are defined, the User Agent may emit key frames as it deems fit.".
