Release 1

• Expected in February 2013 • Goal is to support installation and piloting by

partners • Functionality

• File upload, transcoding & descriptive metadata: manual or batch • Batch loading via dropbox and tabular data file • Authentication and authorization – optional integration would require use

of LDAP or some minor programming • Red5 and Adobe Flash media server support • Discovery via Blacklight faceted search & browse • Playback on desktop browsers & mobile devices (iOS & Android)

12

Matterhorn Unconference 2013 1/30/2013

Release 1 Pilot Support

• Distribution packages • Both source distribution and some form of preconfigured

package, e.g. VM image • Installation & configuration documentation • Email support • Advice on hardware & software requirements in Feb

• Goal: Small pilots/tests can be run on one server or VM; larger scale use may require distributing functions across multiple machines

• Content & metadata from pilots can be migrated forward to future versions

Architecture and Matterhorn Integration • Matterhorn configured for Avalon and run via

Felixwrapper. • Custom workflow and encoding profiles • Rubyhorn service creates media package and

receives thumbnail and poster images

Matterhorn Unconference 2013 1/30/2013

Engage Player • Calls episode and series service but doesn't really use anything

except the mediapackage • 1) Our code is at https://github.com/variations-on-video/hydrant-

engage • 2) Flash player changes: fixes for dynamic initialization to allow

stream switching, debranding, tweaks, and bug fixes • See https://github.com/variations-on-

video/matterhorn/compare/5455b5e...5d9644b • 3) Player page changes include: taking out generic css styling,

dynamic player initialization allowing stream and player switching (HTML5 vs flash), debranding, bug fixes

• See https://github.com/variations-on-video/hydrant-engage/commits/master/public

Matterhorn Unconference 2013 1/30/2013

Developer Concerns

• Is there a path to integrating our changes back into Matterhorn?

• Will there be a re-write for the engage player? • Can we make the install process simpler for

adopters?

Matterhorn Unconference 2013 1/30/2013

Metadata for R1

• Descriptive metadata • MODS

• Technical and Structural metadata • Will be a focus after R1

• Still looking at PBCore, for technical metadata and/or as an export format

18

Matterhorn Unconference 2013 1/30/2013

Beyond R1 • Releases every three months • Workflow & batch loading improvements • Authorization improvements • Structural metadata for navigation • Playlists and clip making • Easy player embedding • Transcripts • Publishing out to other systems • More optimization for mobile • Focused accessibility work

• We want to know what potential adopters’ priorities are.

Other areas of interest

• Contributing code changes/additions • Can Engage become a more general purpose player for

higher ed? • Best practices for Matterhorn deployment and

management? • Potential need for Avalon to work in non-Matterhorn

environments – Support for other transcoding solutions – Calls from Engage Player

• Other use cases for Avalon-Matterhorn interaction
