Latest Releases JW Player JW Platform iOS SDK Android SDK


Specify playback start time and more

iOS 3.13.0 is packed with updates including, startTime support, the new program-date-time metadata type, and so much more!


Release Date: April 27, 2020 (Build 117)


  • Added support for a startTime property that allows developers to define the number of seconds from the start of a media asset when playback should begin. More information and code samples can be found here.
  • Added program-date-time metadata type found in JWMetaEvent. The program-date-time metadata event fires when playback enters the section of an HLS stream tagged with #EXT-X-PROGRAM-DATE-TIME. Note: #EXT-X-PROGRAM-DATE-TIME support requires iOS 9.3+
  • Upgraded iOS SDK to use JW Player 8.13.1.
  • Exposed pauseReason parameter in the onAdPause event.
  • Added adStarted, adBreakStart, and adBreakEnd events for the Google IMA ad client.
  • Updated Google IMA ad delegate methods to ensure delivery of consistent values through the ad events objects.
  • Updated Google IMA ad events order. onAdTime is now fired after the onAdPlay event is fired.


  • Fixed an issue where manifest requests are made multiple times per day. Now the manifest is only requested once per day or if the SDK version changes.
  • Fixed an issue where the player remains in playlist mode (displaying the next up and more buttons) when it is loaded with a single item playlist after being initialized with a playlist of multiple items.
  • Fixed an issue where occasionally Google IMA DAI pre-roll ads would start a split second after playback.
