Creating On-Demand Assets

You may use another encoding source (rather than encoding.com), 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. The set of
multi-bitrate video profiles along with the Asset Description file, are, together, "the asset."
Important!
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 does
not get expired.
You begin by determining how many bitrate profiles for a video you want to encode; see
"Encoding Requirements" on page 252
Step 1 – Encode multi-bitrate (MBR) profiles for each video; see
Conventions for On-Demand
Step 2 – Create AssetDescription.dat File for On-Demand
Step 3 – Pre-Stage On-Demand Assets
or Media Flow Controller.
