New features and functionality

May 9, 2024

Wowza Flowplayer v3.11.1

Wowza Flowplayer v3.11.0

  • Updated the hls.js library to v1.5.8 in order to fix issues with DAI-timed metadata and some older encoding profiles.
  • Expanded the player configuration start_time option to better manage the start of a live stream. This property previously applied to video-on-demand content only and wasn't configurable for live streams. However, you can now use it to programmatically control where a live stream starts on playback, either at the stream's live edge or at the beginning. This change helps customers with real-time streams (RTS) and advertisements to maintain a real-time feel. To seek back to the edge for live streams previously, you had to click Live in the player UI after an ad played. For more, see Core player configuration.

Wowza Flowplayer v3.10.3

  • Enhanced the Server-Side Ad Insertion (SSAI) plugin to provide several improvements for our integration with Google's Interactive Media Ads Dynamic Ad Insertion (IMA DAI) SDK. As part of these changes, we:
    • Updated the SSAI DAI implementation to align it with the latest changes from Google, including support for pod serving DAI.
    • Modified the SSAI DAI user interface to more closely resemble the Advertising plugin user interface.
    • Refactored the SSAI DAI player user interface so it can be created and customized using web components. For more information, see Web components and Plugin components.
    • Updated the SSAI plugin to allow for the ability to eventually expose DAI ad tag analytics in the Wowza Video platform.

Wowza Flowplayer v3.9.0

  • Enhanced the digital rights management (DRM) plugin by implementing v1.3.0 of the hls.js library to allow support for multiple DRM providers for HLS.
