Viblast Player v6.10 introduces HLS audio-only support

Dec. 4, 2015

The latest Viblast Player update, v.6.10, brings support for audio-only HLS streams to our HTML5 media player. Audio-only streams are important to companies who offer audio-only webinars, produce audio webcasts or stream online radio channels, among others.

You can download the new version here or visit the player’s webpage to learn more about our solution.

Beyond the new features, for all of you already using Viblast Player, you may be happy to see certain bugs fixed - thank you for your feedback!

The full release notes for Viblast Player v.6.10

  • Support for audio-only HLS streams (thanks for the nudge, Mike!)
  • Support for HLS streams that contain raw ADTS (AAC) audio (thanks, Greg, for your help!)
  • Implemented support for real-time synchronization using HLS #EXT-X-PROGRAM-DATE-TIME
  • Fixed calculation of HLS VoD clip duration (previously the duration of the first segment was not taken into account)
  • Fixed seeking at the absolute end of an HLS VoD clip (thanks, Richard!)
  • Fixed Flash playback of MPEG-DASH streams that have interlaced audio/video
  • Fixed leaking viblast.crypto.js worker (thanks, Sergey!)

And finally, a few notes about audio-only streams. These are the features supported by the new functionality:

  • On-demand and live streams
  • ABR  (variant playlists)
  • <audio> tag
  • <video> tag with audio-only stream
  • AAC ES streams and AAC TS streams
  • AAC-LC and HE-AAC codecs
  • API for variants of stream audio qualities info (same as for video qualities)
  • Flash fallback via video.js

 There are some known limitations:

  • audio> tag cannot be used with video streams.
  • <video> tag should be used when the playlist contains CODEC information exposed.
  • Auto-ABR switch is supported for multi-bitrate streams with identical encoder settings. Due to Chrome MSE limitations, auto-switching between AAC-LC and HE-AAC causes unpredictable behaviour.

If you have questions or comments, do not hesitate to post them here or on the Viblast Discussion Forum, where they will find a quick response either by us or by our growing community.
