ST2110InputReceiverAdvanced.frameBufferSize property

Number of frame buffers MTL keeps in flight on the receive side — a count, not a byte size. Larger gives the downstream consumer (zig coalescer → PS handler) more headroom against scheduling jitter without making MTL’s RX path drop packets. Defaults: 8 for audio (cheap, ~12 KB total), 2 for video (each slot is megabytes for raw frames). Bounded by MTL’s ST20_FB_MAX_COUNT (8) for video.
