Virtual-Player Type Youtube - Juniper MEDIA FLOW CONTROLLER 2.0.4 - ADMINISTRATOR S GUIDE AND CLI Administrator's Manual

Media Flow Controller CLI Commands

virtual-player type youtube

Use type youtube (formerly type 5) virtual players to allow caching, and support seek, for
YouTube™ FLV and MP4 media using time offsets. Use no virtual-player <name> to delete.
See "Using Virtual Player Type youtube" on page 77

assured-flow {auto | query-string-parm <string> | rate <kbps>}
cache-name video-id query-string-param <string> format-tag query-string-

Notes:
•
assured-flow
least at the specified rate (but no more than the configured connection max-bandwidth)
for the session. In prefix mode, use no assured-flow to re-disable, if needed. By default,
AFR is disabled (no delivery rate is assured). See
Flow" on page 72

query-string-parm

rate
•
cache-name
•
video-id
ID (for example, id). You Tube video URI requests do not specifically associate a
name to a video asset in the URI, instead a unique query param is used.
•
format-tag
format (for example, fmt or itag). You Tube video URI requests do not specifically
associate a format to a video asset in the URI, instead a unique query param is used.
Acceptable format values are shown in
page
•
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.
•
fast-start
available bandwidth; in prefix mode, use no fast-start to disable (default is disabled).
•
query-string-parm
•
size
•
time
•
—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:
380 virtual-player type youtube
—Set AFR for this virtual player, this assures that content is delivered at
for example.
—Not supported in Release 2.0.4.
—Specify a string; referenced value must be in kilobytes.
—Define a static value, in kbps. A value of 0 (zero) means no throughput at all.
—Set query params for:
—Specify a query param string whose value provides the requested video
—Specify a query param string whose value provides the requested
77.
—Set the maximum bandwidth for a session. The actual

—Specify a string (associated value must be in kilobytes).
—Define how many kilobytes should be expedited.
—Define how many seconds should be expedited.
