Version 2.63 was released as a maintenance version, and includes some accessiblity improvements, specifically to IVQ accessiblity. Refer to the Release Notes for IVQ for details.


Release 2.62

  • New Autoplay handling: Safari 11, released on September 19 for iOS11 and macOS, no longer supports autoplay for videos with sound. When set to autoplay, videos must now start muted, with sound enabled only upon a specific user interaction with the player itself.
    Version 2.62 of the Kaltura player includes an automatic fallback to the muted autoplay option. By default, the player will now fall back onto muted autoplay for browsers that block sound. You can also choose to fall back onto an explicit 'Play' initiation on such browsers if you do not wish to play muted videos at all (set ‘autoPlayFallbackToMute’ FlashVar to False).
  • The Safari change temporarily affected the ads flow due to a bug in Google’s IMA plugin. The IMA issue was causing the first transition between a video and an advertisement to be considered as a new playback, requiring additional user interaction. This has now been fixed and the fix was incorporated in 2.62, so that ads do not require additional user interaction.


Known Issues:

  • Post-sequence bumpers will require an additional play click after the video ends
  • Playlists with ads  - Each video in the playlist will require an additional play click

Release 2.61

Changes to 360 Flashvars – Flashvar names have been changed for simplicity:

  • ‘VR’ will now be called ‘enable_vr’, meaning the VR plugin s enabled and 360 videos can be watched.
  • ‘vr_mode’ will now be called ‘auto_load_as_vr’, meaning the video will load in VR mode (i.e, in split screen mode compatible with a VR device)

Release 2.60.2

  • Call-to-Action Buttons: This release allows the user to add up to two brandable Call-to-Action Buttons at the end of playback, with or without related videos. Buttons defaults are defined on the player and can be overridden using entry custom metadata and embed flashvars.For more information, please see Universal Studio Information - Call to Action Buttons.
  • Limitations:

    • Only one custom data profile can be defined on the player. If custom data profile is used by any other plugin, CTA metadata fields should be added to the same custom data profile
    • CTA without related videos is supported on video-on-demand, audio-on-demand (if the player includes a screen display), and YouTube entries; it is not supported on image entries, in-video-quizzes, and live entries.
