In v1.5 HLS.js uses ManagedMediaSource by default when available. This lets the user-agent suggest when to pause and resume streaming. To disable it, set "preferManagedMediaSource" to false.

Also note that streaming uses maxBufferLength or maxBufferSize * active bitrate (which ever comes first), up to maxMaxBufferLength to determine when to idle segment fetching.

BUFFER_FULL_ERROR error events caused by QUOTA_EXCEEDED_ERR DOM Exceptions will result in maxMaxBufferLength being halved.
