SmoothFlow Deployment : Creating On-Demand Assets

Creating On-Demand Assets
You may use another encoding source (rather than, or do the encoding yourself. In this scenario, after creating the multi-bitrate profiles of a particular video, and an Asset Description file, you pre-stage the encoded assets to Media Flow Controller. Note the set of multi-bitrate video profiles along with the Asset Description file, are, together, "the asset.”
Important! You encode the multi-bitrate video profiles yourself if using this procedure.
Note! These assets are called "On-Demand" because the multi-bitrate assets (already encoded) and the Asset Description file are pre-staged to Media Flow Controller and the appropriate profiles are served as client requests arrive (on-demand). When bandwidth at a client rises, a higher bitrate profile chunk is served; when bandwidth falls, a lower bitrate profile chunk is served.
Tip! Set the cache-age to a high value for the SmoothFlow namespace so that content doesn’t get expired.
You begin by determining how many bitrate profiles for a video you want to encode; see “Encoding Requirements” on page 322 for more information.
Step 1 – Encode multi-bitrate (MBR) profiles for each video; see Bitrate Profiles Naming Conventions for On-Demand Assets next.
Step 2Create AssetDescription.dat File for On-Demand Assets.
Step 3Pre-Stage On-Demand Assets (multi-bitrate files plus Asset Description file) to origin or Media Flow Controller.
Step 4Initiate SmoothFlow Processing for On-Demand Assets via a processing "trigger" request.
