Step 1 of nescore's 2026-10-16 media timing spec. Media carried no send time and audio no time at all, so every layer had to infer lateness from gaps between arrivals. - clock: one sender clock, CLOCK_MONOTONIC in u64 microseconds, shared by every process that stamps media. Off unix the client uses its own process clock, which is all a receiver needs. - Datagram headers (and PyroWave's) carry sent_us, stamped by neshub at hand-off to QUIC. Keyframe streams open with it too. - Video carries captured_us (from nescapture's present time) in place of milliseconds since the encoder started. Audio carries its first sample's position on the PipeWire graph clock, which neswire already read to fill missed cycles. The IPC stamp is a u64 carrying either. - delay: microseconds. The baseline no longer expires on a 30 s timer: clock skew is measured as the least-squares slope of each second's minimum one-way delay, and only a path change resets the baseline. observe() returns each unit's queueing delay. - ReceiverReport carries video and audio queueing delay summaries for the rate control that will consume them. - Shared encode/decode helpers for video and audio payloads, so the hub and receivers stop hand-building byte offsets. No compatibility kept. STREAM_VERSION is 4. nescore needs a pin and the client side (step 2) before it can talk to this. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
