Streaming High Quality Mobile Video… A Conversation and Some Code! Very informative presentation by Dean Blackstock, PennState, World Campus addressing the technical challenges of delivering high quality video to students in the educational environment. Can’t wait to check out the link he provided to the code he has created!

Here are my notes:

Kaltura (third party vendor) Integrated w/D2L (Note to self: need to learn more about this!)

Wowsa server

New Flash media server 4.5 added support for iOS

Progressive vs Streaming

Progressive
– copyright issues
– everyone gets same video file regardless video
– streaming needed full length feature film
– metrics not consistent because video is downloaded

Streaming
– improved navigation
– allows scrubbing
– live videos
– varying bit rates – detects users bit rate needs (has mobile version)

Http streaming enabled
– just-in-time packager
– flash for desktop/laptop browsers
– HTML 5 fallback for iOS
– Security – embed code won’t be read from other server

Student watching behavior
– Students watch only 4 to 8 minutes at a time

Challenges
– outdated plugins, JavaScript disabled
– secure networks (can trick user into thinking it is just a web page) New server does testing of ports for you

Delivery
– iOS – web, mpeg4, JW player

IPad
– no indication that there’s info below the fold

Bug in IE7 – click twice on Flash player

Mobile example
– Free JW player
– traditional web server

Paste Google Analytics identifier

Flash player not supported, flash media server is supported, will change name to adobe media player, HTML 5 standard has not been adopted yet
