Bugfixes
#3608 Git hooks: Fix path problem on Windows
Link: Fix a bug for dynamic streams with multiple video AdaptationSets. MPD update lead to selection of wrong MediaInfo
Link: Fix a bug when switching between multiple thumbnail tracks
Link: Fix for BUFFER_LOADED event never triggered when minBufferTime > stableBufferTime
Link: Do not hide time display in ControlBar.js whenever liveThresholdSecs is reached to avoid seeking problems
#3625 Fix seek to DVRWindow.start
Link: Fix a bug in the playFromTime.js functional tests. stream url was overwritten and not restored
Link: Fix a bug in the calculation of the segment availability end time when the value is set to Infinite
Link: Remove unnecessary protectionController.setMediaElement call
Link Do not apply strong comparison in the EventController.js when checking a value
Link Do not handle abandoned fragments in case the abort was triggered by a representation switch
#3643 Fix segmented text track selection
Link Abort requests when deactivating a stream
Link Fix config bitrate when using configRatio. Value needs to be specified in kbps
#3652 Fix offline module
#3654 Fix a bug that lead to starting the the schedule timer twice
Link Fix wrong reference to streamInfo once buffering is completed. Due to this, signalEndOfStream was not called for multiperiod VoD streams and playback stalled some frames before the end.
Link Check if we can start prebuffering after an MPD update. New periods might have been added
Link Use type for calls to getCurrentDVRInfo if required. Otherwise audio only is not working properly.
[Link] Delete texttracks based on period boundaries and do not disable track when period switches
#3669 Fixes the error on entering/leaving full screen on Chrome
Link Fix a bug in the TimeSyncController.js which causes time syncs to be blocked once the sync attempt failed
Link Fix xhr check in setup function of functional tests
Link Fix a bug in the low latency demos
#3680 Update/fix typings in index.d.ts
