Today we are releasing version 1.2 of the JW Player SDK for Android. This version focuses on improvements in performance, flexibility, stability, and adds the following features:

  • Faster HLS Video Startup. 5x faster adaptive HLS video startup with minimal buffering.
  • Improved HLS playback performance.
  • Second-precise seeking
  • Improved support for advanced HLS features, such as discontinuities
  • Takes the current CPU load into account when determining which HLS stream variant to play
  • Improved bandwidth detection heuristics for faster adaptivity and optimal resolutions
  • Show/hide player control bar.  Added an API method for showing and hiding the media player control bar.

How Much Faster? A Side-by-side Comparison

The following “HLS Startup Speed” video compares the native Android Media Player to our JW Player using the latest JW Player SDK for Android 1.2 version.

The native Android Media Player is playing in the Google Chrome browser app v.43 with the video embedded using the HTML5 “video” tag.

JW Player is playing in our JW Player Android Demo app v.1.2 using the JW Player SDK for Android v.1.2.

Both apps are playing the same HLS video on the Samsung Galaxy S5 SM-G900H with Android 5.0; the Wi-Fi bandwidth was throttled using Charles Web Debugging Proxy v.3.10.1 to the standard 3G (1024 kbps) setting.
