Speed

Sets the available rates at which the media can be played back. This is an Array attribute that is used to implement user controls for fast forward, slow motion, and so forth. The normal playback rate is multiplied by this value to obtain the current rate, so a value of 1.0 indicates normal speed. For the viewer guide, see Playback Functionality.

How do you configure the playback speed?

  1. In the Player Studio, click on a player to open its Player Settings window.
  2. Scroll to the end of the page and select Advanced Settings.

Autoplay

Start playback automatically.

  • Type: boolean
  • Value: The default value of this property is false.
    If set to true, playback will start automatically when the player receives the content.

Custom tag for VR mode

By default, the Kaltura Player enables VR mode for any video tagged with 360 (or variations). However, some videos may automatically receive this tag (like technical or math-related ones), even if they aren’t 360° videos, causing playback issues.

To change the tag that triggers VR mode:

  1. Go to the desired player's Advanced Settings tab and locate the "provider" object in the settings list.

  2. Click the green (+) button next to "provider" to add a new property.

  3. In the Key Name popup that appears type vrTag

  4. Click the green check mark to complete the action.
  5. Click the pencil (edit) icon next to the red "null" value.

  6. Delete "null" and type your custom tag, for example, my__360__tag (do not add quotes - the system will add them automatically).

  7. Click the green check mark to save your changes.

    8. Now the VR button will only appear for videos that specifically have the tag you set, preventing incorrect playback in VR mode.

  8. Click Save at the top right of the settings window.

 Make sure all relevant videos in your account are updated with the new tag. Only videos with this tag will trigger VR mode.
