Payload-specific feedback (PT 206): PLI, FIR, SLI and REMB.

Modules

full_intra_request

FIR: asks a sender for a full intra frame, used when a receiver joins or resyncs.

picture_loss_indication

PLI: tells a sender the receiver lost picture and needs a keyframe.

receiver_estimated_maximum_bitrate

REMB: the receiver’s estimate of the bitrate the path can carry.

slice_loss_indication

SLI: reports individual lost slices, for finer-grained repair than PLI.
