buildRateEnvelope(
options): readonlyCurvePoint[]
Defined in: packages/sdk/src/rate-envelope.ts:32
Compile a rate envelope (segmented playback speed) into equivalent curve
time-mapping points. The envelope integrates rate over timeline time: each
segment advances the source time by rate * durationUs. Item time is
strictly increasing. Source time may advance, hold, or move backward,
allowing deterministic forward, freeze-frame, and reverse spans.
Returns at least two points; a single segment produces the two endpoints.
