We are trying to understand keyFrameRequestDelay option. In the Scalability section, at: https://mediasoup.org/documentation/v3/scalability, it says:
If the encoder receives many PLIs or FIRs (although mediaoup protects the producer endpoint by preventing it from receiving more than one PLI or FIR per second)
but in the documentation (https://mediasoup.org/documentation/v3/mediasoup/api/#ProducerOptions) it says:
Just for video. Time (in ms) before asking the sender for a new key frame after having asked a previous one. If 0 there is no delay. (default:0)
Is there a default of 0 or 1 second, are those two distinct mechanisms?
Also, when discussing a single producer, and hundreds or thousands of viewers, does it really makes a difference if the producer need x2 or x3 bitrate?
