Recent Releases:

JW Player 7.4 - May 10, 2016

Apple HLS adaptive streaming is the most widely used streaming technology. JW Player now supports HLS in HTML5 through Chrome’s Media Source Extensions. HTML5 playback of HLS in the world's most used browser decreases the time to first frame and further reduces the reliance of Flash as a video rendering technology. With only a few exceptions, HLS in HTML5 will work as it did with Flash, just faster!

TV Casting - Apr 8, 2016

JW Player SDK for Android 2.2 gives developers a simple, out-of-the-box ability to search for available Chromecast devices and wirelessly cast videos from their mobile app to any selected Chromecast device. We currently support HLS adaptive streams and MP4 progressive videos and viewers will be able to pause, play, seek, and control playback from the mobile app.

JW Player SDK for iOS 2.2 supports casting to Chromecast devices just like the Android SDK, but with iOS we also make it easy for developers to enable viewers to wirelessly stream content using AirPlay and control playback directly from the iOS app to any AirPlay enabled device (for example Apple TV).

CDN Accelerated Uploads - Mar 3, 2016

CDN Accelerated Uploads leverage our CDN edge nodes to dramatically (up to 10x) improve the upload speed of videos. Customers in South America, Asia and Oceania in particular will benefit from this upgrade.
