Mid-segment switching

Things to aim for

  • turn the in-memory buffer from segments to tags
  • in drainBuffer, seed in enough tags so that 1s (less? more?) of content is in there, with at least a delta of one keyframe
  • when new segments arrive, replace overlapping tags in the in-memory buffer
    • never replace tags in previous discontinuities

Equations

Vars

  • current segment duration: tₖ
  • proposed segment download estimate: tₙ
  • proposed next segment download estimate: tₙ₊₁
  1. tₙ₊₁ + tₙ < tₖ
  2. tₙ < tₖ * 1/2

  • current segment duration: tc
  • proposed segment download estimate: tn
  • proposed next segment download estimate: tn+1
  1. tn+1 + tn < tc
  2. tn < tc * 1/2
