v3.9.1

Release 3.9.1 (2018-11-13)

Overview

This release fix issues regarding the manifest-refreshing logic for both Smooth and DASH:

• for smooth contents, the player could stall indefinitely when playing a live content close to the live edge and switching a text, audio or video track

• for dash contents with a minimumUpdatePeriod attribute and a customManifestLoader argument given to loadVideo, the manifest could be refreshed too often

To lower the memory usage when playing Smooth live contents for a long time, we also now clean-up regularly the informations we have on segments becoming unreachable.

Infinite rebuffering issue with Smooth live contents

The main fix concerns Smooth contents, where the player could stall indefinitely when playing live contents.

It was due to two issues in our Smooth Manifest refreshing logic:

• we overwrote the previous segment informations we had when refreshing the manifest
• we had a time-conversion error which prevented emergency Manifest updates to happen

This could mostly be experienced when switching to another audio track in specific situations (live content, close to the live edge...), those two issues could combine and lead ultimately to a player staying in a rebuffering state.

This release fixes both of these issues.
