Latest version of Wowza Player


The latest version is Wowza Player 1.1.16 build 8916 released on February 19, 2019.

Changes (since 1.1.15)

  • Improved ABR switching behavior under reduced bandwidth conditions.
  • Fixed an autoplay issue for the Safari browser. Previously, streams with autoplay enabled and mute set to false would fall back to manual playback settings as expected, but playback would freeze after manual playback was initiated.
  • Resolved an issue with audio-only streams where they would't play in the Safari browser when the audioOnly configuration property was set to true.
  • Fixed an issue with the JavaScript API play method where playback would fail after pausing a stream.
  • Updated documentation for the JavaScript API destroy method to provide a correct description and code examples.

Earlier versions of Wowza Player


1.1.15 build 8843 – released December 18, 2018

  • Resolved an issue with HLS streaming where the callback function for the onMetaData method did not execute when an ID3 tag was available in the stream. 

1.1.14 build 8825 – released December 12, 2018

  • Enabled autoplay, a feature that was disabled in version 1.1.06. With the autoPlay configuration property set to true, Wowza Player plays content automatically if the browser supports it. If the browser doesn't support autoplay, Wowza Player falls back to manual playback controls. See Use autoplay with Wowza Player for more information.
  • To hide or show elements in the player user interface, added new configuration properties, uiShowSeekBaruiShowVolumeControluiShowPlaybackControls. You can now hide the entire player user interface or any element of the user interface with a full set of UI configuration properties, including existing properties uiShowQuickRewinduiShowFullscreen, and uiShowBitrateSelector.
  • Added the ability to start live DVR playback from the oldest point instead of the live point by setting the new configuration property startAtLivePoint to false.
  • Added JavaScript API methods onPlaybackAttemptonPlaybackSuccess, and onPlaybackFailure that include event listeners to detect when Wowza Player attempts to play a source, when the attempt succeeds, and when the attempt fails.
  • Fixed an issue where HLS streams with failed playback would not fall back to WebSocket streams.
  • Removed overlay of exclamation point graphic over video when first playback fails and second succeeds.
  • Resolved an issue where keyboard controls for audio-only playback didn't work as expected.
  • Fixed an issue where the native iOS player wouldn't play source URLs from a sources array, including fallback functionality from ultra low latency WOWZ over WebSocket streams to HLS streams.

1.1.13 build 8693 – released November 6, 2018

  • Performed internal license administration updates.

1.1.12 build 8600 – released October 10, 2018

  • Fixed bug where WebSocket AMF event payload was dropped from onMetaData event if the payload consisted of AMFDataMixedArray.
  • Fixed an issue where audio-only streams were failing to play after bitrate switch.
  • Removed Wowza brand logo from audio-only player.

  • Fixed probem where DVR would incorrectly resume from live point.
  • Implemented new adaptive bitrate algorithm that performs better down-shifting in bad network conditions.
