•
health-probe
Controller fetch data from origin and play it to the server initiating the health check. The
signal that a given HTTP request is for a health probe is the health-probe query-string-
parm name. If that name value matches the following <string> value, the GET request is
treated as a health probe. When servicing health probes, Media Flow Controller does not
cache the data into disk or in buffer. Use virtual player <name> type 3 no health-probe
to disable.
•
req-auth
auth-id, a configured shared-secret, and time-interval; and match the computed value
with the specified match query-string-parm <string>. The HTTP GET proceeds if the
computed MD-5 hash matches; if there is no match, the session is rejected. Use virtual
player <name> type 3 no req-auth to disable.
Type smoothflow
The type smoothflow (formerly type 4) virtual player configures SmoothFlow. It is a
requirement of SmoothFlow that this virtual player be configured and used through a
configured namespace. The Type 4 virtual player includes connection max-bandwidth,
hash-verify, and seek options (see
•
control-point
then Media Flow Controller detects the bandwidth variations at the client side and adjusts
the bit-rate of the video accordingly. If player, then the player at the client side explicitly
signals the bandwidth changes and Media Flow Controller adjusts the bit-rate of the video
accordingly.

signals to disable.
•
session-id query-string-parm
session ID; default is sid. Session ID is the way you bind the control session that
signals the bandwidth change with the data channel.
•
state query-string-parm
SmoothFlow state; default is sf. The values this query param take signal various
function calls to SmoothFlow.
•
profile query-string-parm
bit-rate profile; default is pf.
Type youtube
The type youtube (formerly type 5) virtual player is designed for YouTube and offers a subset
of Media Flow Controller delivery options: assured-flow, connection max-bandwidth, fast-
start, seek (see
requested video, video-id, and its format, format-tag.
Type smoothstream-pub
The type smoothstream-pub virtual player supports Smoothstream functionality for Internet
Information Se4rvices (IIS) for Windows® Server.
