Wowza Player

Version: 1.1.21
Date   : 2020/04/27 23:37:01
1.1.21:
   * onBuffer: event will be created to help report the Wowza Player buffering status. onBufferStarted will be raised when the 
     underlying browser video system (MSE) determines it is starved for media data, typically resulting in a temporary freeze 
     of the media. As soon as underlying browser video system (MSE) determines it has enough media to continue playing, 
     the onBufferingFinished event will be raised. After which the playback process should resume.
   * onError: Changes will be made to the onError event messaging to ensure that unexpected session drops that can be detected will be
     reported. Specific error messages in the onError event that correspond to session drops with be provided along with a description 
     of the scenario under which that message covers.
   * onMessageDelay – This event will be added to indicate when web socket messages are taking longer to arrive, due to a gap between messages.

1.1.20:
   * Fixed a playback issue on smart TV apps and on Safari running on iOS version 13 and higher where the video aspect ratio was altered unexpectedly.
   * Fixed a problem where Flash playback did not function as expected.
   * Fixed a playback issue for Android mobile devices that resulted in a 'live stream has ended' error message.

1.1.19:
   * Fixed an issue with handling of the nal_ref_idc value in the Sequence Parameter Set (SPS) that resulted in non functional playback.
   * Fixed an analytics reporting issue.

1.1.18:
   * Generate HTML5 only player (no Flash Fallback) artifact with release build. 
   * Added enableCatchUpJumpToLive flag in order to jump to live point when ULL stream reconnects.
   * Fixed parsing private ID3 tag values.
   * Fixed Media decode error issues in ULL streams.
   * added wsCatchUpJumpToLive flag in order to jump to live point when ULL stream reconnects.
   * Fixed parsing private ID3 tag values.

   * Improved Wowz catchup behavior to happen under more conditions where it is needed
   * Hooked up re-buffering logic and UI during wowz playback
   * Implemented accurate seek
   * Added packetTime to onMetadata event
     * For VOD streams packetTime and time will be the same.  
     * For live, the time the client connected is represented at event.time == 0.  event.paxcketTime is the time contained in the original stream
   * Added support for AMF data events of type String and AMFDataList to wowz playback
   * Fixed problem where wowz streams did not purge metadata events leading to Out of Memory conditions

1.1.16:
   * Improved ABR switching behavior under reduced bandwidth conditions
   * Added Latency beacon information to the browser console & this is controlled through "debugLatencyBeacon" flag.
   * Fixed 'sourceBuffer removed' error when play() was called explicitly on player.
   * Fixed an autoPlay issue for the Safari browser. Streams with autoPlay enabled and mute set to false should fallback to manual playback without playback freeze

1.1.15:

1.1.14:
   * Added ability to start live DVR playback from oldest point, instead of live point, by setting property “startAtLivePoint” to false
   * Fixed overlay of exclamation point graphic over video when first playback fails and second succeeds
   * Added listeners for listening to when playback of a source is attempted, succeeds or fails.  Each method accepts a function which receives an event:
     - onPlaybackAttempt()
     - onPlaybackSuccess()
     - onPlaybackFailure()
   * Fixed failure of an HLS source to fallback to a secondary ws/wss sourceURL
   * Resolved an issue where keyboard controls for audio-only playback didn't work as expected
   * Added new properties 'uiShowSeekBar', 'uiShowVolumeControl', 'uiShowPlaybackControls' to hide UI from the player.
   * Implemented autoPlay functionality (As per browser recommendations)
    - Setting “autoPlay” flag to true
        - If browser support autoplay Wowza Player will support autoplay functionality
        - If browser doesn’t support autoPlay Wowza player will fallback to manual playback.
