Notes:
•
connection max-bandwidth
session bandwidth is between the AFR (Assured Flow Rate) and this value. Even if there
is available bandwidth in the link, Media Flow Controller does not allocate more than this
value for a session. When it is a full download, Media Flow Controller tries to allocate the
max-bandwidth to the session. Default is 0 (unbounded) with the Media Flow Controller
license, 200 kbps without it; you must have the license to change the unlicensed default.
In prefix mode, use no connection to reset the default.
•
control-point
player, the player at the client side explicitly signals the bandwidth changes and Media
Flow Controller adjusts the bit-rate of the video accordingly. If server, Media Flow
Controller detects the bandwidth variations at the client side and adjusts the bit-rate of the
video accordingly.
•
signals
must understand the query params you configure here; defaults are sid (for session-id), sf
(for state), and pf (for profile).
•
session-id query-string-parm <string>
signal the session ID; default is sid.
•
state query-string-parm <string>
state; default is sf. The allowed values (sent by the client player) are 0, 1, 2, 3, and 4
and these denote: 0=disable SmoothFlow; 1=start a SmoothFlow session; 2=client
player request for client Asset Index file; 3=client player request for profile adaptation;
4=initiate SmoothFlow processing for content (chunks and names video files, creates
the Asset Index file if needed, and queues content).
•
profile query-string-param <string>
media bit-rate profile; default is pf.
•

•
match query-string-parm
default for this virtual-player type is h.
•
shared-secret {append | prefix}
prefixed (as specified) to the URI, to calculate the hash which is then "matched" with
the match query-string-parm hash value.

—Specify a string to implement FLV seek (allows the client player to seek to a
seek
specific location of the URL). In prefix mode, use no seek to disable. Optionally:
•
seek-length query-string-parm
of data to send from the seek start position; referenced value must be in bytes.
•
enable-tunnel
this option needs to be selected only when the origin site changes their seek
mechanism. Default is disabled.
—Specify either server or player (default) for SmoothFlow signaling. If

—Verify the hash value specified in the URL (see
for details); in prefix mode, use no hash-verify to disable.
—Only md-5 is supported in Release 2.0.4.
