OSMF 2.0 now available!

The online video world continues to grow at breakneck speed and we, at Adobe, have been fortunate to be a big part of making it happen. More video content is available today than ever before and the trend is only accelerating. The World Cup drew a record number of online viewers online and engagement levels were the highest. Users could switch multiple camera angles, watch highlights and watch on demand. I am looking forward to seeing more content, more engaging experiences and higher quality.

Adobe’s mission has been to enable you to create great content and bring it to your audiences. We are thrilled to announce the launch of OSMF 2.0. The new version of OSMF 2.0 allows you to create even more engaging experiences for your audience. We worked with some of the largest content owners with the largest online video audiences and have reworked the inner workings of OSMF. In particular, we have made major changes to the Adaptive Bit Rate (ABR) algorithm and the APIs for ABR.

The OSMF Adaptive Streaming provides two modes: i) Manual switching and ii) Automatic switching. As part of the changes, we have improved the automatic switch operation; added more information to the Quality of Service (QoS) information and history; enhanced the metric base, factory and repository; and finally optimized the rule engine to better handle bandwidth and other computer resources. More details on the changes can be found here:

We hope you are as excited about this release as we are. As always, we look forward to hearing your feedback on this latest release. Thanks for your support.

Announcing OSMF and Strobe Media Playback 1.6

2011 has already been an exciting year in the world of online video. Fabio’s battle with the Old Spice Guy, the realization of TV Everywhere, user-generated videos and the Arab Spring (not to equate the importance of any of these!) – these all testify to online video’s ability to resurrect careers, entertain, and literally change the world.

As online video evolves, the technology that supports publishing video must follow. With that objective in mind, I am very proud to announce the release of OSMF and Strobe Media Playback 1.6. Over the past several months, you have provided us with valuable feedback, and that became the foundation for this release.

What’s new?

Mobile: Video usage on smartphones and tablets continues to grow rapidly. Just today, Knowledge Networks published that video viewing on mobile devices among 13 to 54 year olds has doubled over the last year. As part of the 1.6 release, we have included new features that will help you bring your content to mobile devices.

Enhanced Viewer Experience: One of OSMF’s core objectives has always been to enable you to create engaging experiences for your viewers. Towards that end, we have released the following features.

  • OSMF: DVR rolling window support, which allows you specify how far back from the live point viewers can rewind (requires the newly released FMS 4.5)
  • OSMF: Late-binding audio for providing viewers with multiple audio track options, e.g. additional languages, director’s commentary, and “home” v. “away” coverage

Core Framework: Beyond new functionality, we continue to improve the existing core framework. In OSMF 1.6, we have made improvements to HTTP Dynamic Streaming as well as the ability to better manage bitrate profiles with multi-level manifests.

Documentation: We have made the first major step in improving our documentation with the launch of a completely revamped wiki for OSMF and Strobe Media Playback. We hope this will make finding information and resources on specific topics easier, and I encourage you to bookmark it for future reference.

We look forward to hearing your feedback on this latest release. As always, you can reach me at ckwon at adobe dot com. The developer forums are also great venues for discussion, and the team regularly monitors these as well.

Thanks for your continued support!

OSMF 1.6 Sprint 3 is here!

We have just released the next sprint drop for OSMF 1.6.  We continued to address some important bugs, a list of which can be found in the release notes.

We also want to make sure everyone is aware of the following: If StageVideo mode is enabled and a video resource is being associated with a smaller container, make sure that the scale mode will not be set to ‘none’, otherwise, the video will not be clippedaccording to the containers dimensions (this is the expected behavior).

We’ve have some really exciting advanced features in development, so be sure to check back with us over the following months.  As always, feel free to ping me with any questions or feedback at ckwon at adobe dot com.
