Audio-Only Player: Supported Environments, Formats, and Outputs

Supported and unsupported environments for Audio-Only Player

Many of the capabilities we support for Video playback are also available for Audio-Only playback, including the configuration of Player options, variable speed playback, skip forward/backward controls, and up-next capabilities. We also offer the same IQ analytics and Asset Metadata options for Audio-Only Player that we offer for Video.

However we do not yet support some common Video features with our Audio-Only Player, including the video ad plugins (Google IMA, Freewheel, etc.), DRM, multiple bitrates, offline playback, closed captions, and accessibility.

The following environments are supported in this release:

The following environments are NOT yet supported:

  • Apple TV (TVoS).
  • Amazon Fire TV.
  • Chromecast.

Supported and unsupported features for Audio-Only Player

The following features are supported in this release:

  • Clear streaming (Live, VOD) with HLS in AAC (currently only supported for Ooyala HTML5 Player, iOS and Android SDKs)
  • Player Management (Configuring)
  • Player Skin modification
  • Player Controls (Skip buttons, playback speed)
  • "UpNext" (Playlists, Discovery)
  • Syndication Feeds (i.e. for Podcasts)
  • Analytics Support (IQ)
  • Asset Metadata

Currently unsupported features:

  • DRM (Clear Streams only)
  • Ad Plugins (Ads must be stitched into audio stream)

    Note: As a workaround, ads could be built into the stream directly (as part of the source), or converted to a video by adding a slate (and, respectively, using the Video Player for playback).
  • Multiple Bitrates
  • Offline playback (DTO) outside of Podcast syndication.
  • Closed Captions
  • Accessibility
  • Streaming formats other than HLS
  • Autoplay
  • MP3 format (from encoding)
Note: An additional limitation is that a Player set as a Video Player (the default option) cannot play an audio only embed code; conversely, a Player set a an Audio-Only Player cannot play video files.

Supported file formats (general)

Audio-On-Demand:

  • Content ingestion formats (see below for more details): OGG, M4A, MP3, WMA, AAC, and WAV
  • Output formats: OGG and M4A (progressive) and Audio-Only HLS (chunked)

Live-On-Demand:

  • Audio-Only HLS, single bitrate
  • No DRM support yet

Supported file formats for content ingestion

For Audio-Only, the following audio source file formats are supported for ingestion and playback, based on the supported environment:

  • Web (Ooyala HTML5 Player, as of version 4.29.14): OGG, M4A, MP3, WMA, AAC, and WAV for ingestion, and HLS (AAC) for playback.

Supported transcoding outputs

With the introduction of Audio-Only Player, the following transcoding outputs are now available:

  • Audio-Only. Supported transcoding profiles:
    • AAC in HLS (uses FFMPEG for Elemental, and Azure for other renditions if Video content is also included).
    • Muxing format that is called AAC for Audio-Only in HLS, and called TS if it contains Video.
      • Progressive M4A (FFMPEG only).
      • Progessive OGG (FFMPEG only).
    • Audio on-demand file support for customers on Elemental or Azure encoders.
    Note: For Audio-Only output, AAC in HLS is optional; OGG and M4A are supported for all output at all times.
  • Video-Only. This functionality works as before - the supported outputs are MP4, HLS DASH, HEVC.
  • Combined Audio and Video. Supported transcoding profiles:
    • HLS with AAC only (Elemental, Azure).
    • HLS with TS (FFMPEG, Elemental, Azure).
