Environment
  • Link to playable MPD file:
  • Dash.js version: 3.2.1
  • Browser name/version: Chrome
  • OS name/version: Windows 10
Steps to reproduce
  1. Set stableBuffer setting to 60
  2. Launch Chrome, set Network throttle to 'Fast 3G'
  3. Play Multi-resolution video
  4. Pause the video and wait until low-res video is fully buffered in stable. (which is 60 seconds)
  5. Play the video
  6. set Network throttle to 'No throttling'
  7. seek video 10 seconds after, repeat it
  8. If it doesn't happen, repeat 1~7 again
Observed behavior

ScheduleController stops scheduling.
