1. Summary
When using headless playback, the bufferedRangesListener of the playerClient becomes very inconsistent in it’s reporting almost immediately, sometimes reporting in bursts, sometimes with long breaks between reports, and eventually stops responding all together.
Bug Severity
- Impacts operation of app
- Blocks current development
- Improvement suggestion
- Issue with documentation (If selected, please share the doc link and describe the issue)

2. Steps to Reproduce
Start a headless playback sesison, and subscribe to the bufferedRangesListener of the player client
3. Observed Behavior
When using headless playback, the bufferedRangesListener of the playerClient becomes very inconsistent in it’s reporting almost immediately, sometimes reporting in bursts, sometimes with long breaks between reports, and eventually stops responding all together.
4. Expected Behavior
Describe what you expected the SDK to do under normal operation.
We would expect the buffered ranges to update appropriately when the range of the buffered media changes so we can calculate proper seek ranges in the media
