OSMF 1.6 Sprint 5 is here!

We have just released the latest sprint drop for OSMF 1.6, Sprint 5, and the key new feature is support for multiple audio tracks for HTTP Dynamic Streaming, often referred to as “late-binding audio.”  This feature allows publishers to associate multiple audio-only streams with a particular video and present these as alternate audio tracks to the consumer.  For example, if a publisher wants to provide the option of hearing a video in English, Spanish, and English + video descriptions (for visually impaired consumers), they can accomplish this without having to prepare a separate video + audio stream for each.  Each additional audio track can be supplied as an audio-only stream, reducing unnecessary redundancy in content preparation workflows and storage.  OSMF also supports the ability to switch between audio tracks during playback, providing additional flexibility in the user experience.

Late-binding audio is currently available for VOD only.  We are also working on live/linear support, which will be available in our next drop.

Check out Sprint 5 here:

As always, we’re eager to hear your feedback!  Please feel free to reach out to me at ckwon at adobe dot com.

    Sounds great! Is there a demo showcasing this for HTTP Dynamic Streaming and F4F? Or perhaps an example .f4m file?

    Nice work. I moved my project from “Burrito” to Flash Builder 4.5.
    One problem not yet solved: an event from Flex Framework not defined. I think “VideoStageEvent”. It looks like a version problem.
    Any ideas?
