Polling interval recommendation

For number based manifests use auto-polling=True. If the actual duration of the segments is not equal to the duration indicated in the manifest, use auto-polling=False and set manifest-polling-interval to 1/4th of the segment duration .

For time based manifests use auto-polling=False, and set manifest-polling-interval to 1/4th of segment duration in the manifest.
