aboba has just created a new issue for https://github.com/w3c/webrtc-pc: == Effect of RTCRtpSendParameters on Simulcast == The effect of `RTCRtpSendParameters` on simulcast is under-specified. Some questions: 1. Is congestion control affected by the value of `RTCRtpSendParameters.degradationPreference`? For example, if `degradationPreference` = `maintain-resolution` does this imply that framerate is lowered before higher resolution simulcast layers are dropped? Does the opposite happen if `degradationPreference` has the value `maintain-framerate`? 2. Is congestion control affected by the value of `parameters.encodings[].priority`? For example, is a simulcast layer with `parameters.encodings[].priority` of `low` dropped prior to one marked with `high` priority? 3. What effect does `parameters.encodings[].maxBitrate` have? Do the values of `parameters.encodings[].maxBitrate` influence which simulcast layers are dropped? If there is insufficient bandwidth, is bandwidth allocated to the layers in proportion to the values of `maxBitrate`? 4. What effect does `parameters.encodings[].maxFramerate` have? Do the values of `parameters.encodings[].maxFramerate` influence which simulcast layers are dropped? If there is insufficient bandwidth, is bandwidth allocated to the layers in proportion to the values of `maxFramerate`?
