Configuring YouTube Video Caching (CLI)
Configure a youtube type virtual player if you want to cache and optimize the delivery of
YouTube videos. See
“Using Virtual Player Type youtube” on page 77
for more information. To
configure YouTube video caching:
1.
Configure a namespace with the proper URI prefix (/get_video or /videoplayback) and
domain name association to filter YouTube video requests
2.
Configure a virtual player of type youtube to be associated with the above namespace
a.
The cache name & seek configuration are required.
b.
For case (a) described above the cache name configuration is video_id and fmt. For
case (b) described above the cache name configuration is id and itag
c.
For seek configuration, the URI query is begin (seek length is not required)
3.
Default cache age allowed for YouTube assets can be over-ridden using the namespace
origin-fetch options offered by the Media Flow Controller CLI to enable longer cache
intervals.
Example configuration to enable YouTube caching in Media Flow Controller:
test-vos (config) #
virtual-player ytplayerA type youtube
test-vos (config virtual-player ytplayerA) #
cache-name video-id query-
string-parm id format-id query-string-parm itag
test-vos (config virtual-player ytplayerA) #
seek query-string-parm begin
test-vos (config virtual-player ytplayerA) #
exit
test-vos (config) #
show virtual-player ytplayerA
Virtual Player : ytplayerA
Type : youtube
