Samples a keyed keyframe playback and requests frames while it is active.

The stable id owns the playback’s start time. Re-rendering with the same ID continues that playback; it does not restart when keyframes or timing is reconstructed. To replay a sequence, include an application-owned generation in the ID, for example ("notification-enter", generation).
