Second Presentation for MCDS

1. Media Content Delivery Systems 2
“The Update”
…Or MCDS
Brendan Ashby and Lindsey Kennard

2. Recap
 Searching for Alternative Web Media Solutions
◦ Minimal Re-encoding
◦ Support for the latest codecs/containers
◦ Adaptable to a web environment
 Not satisfied with the “flash status quo”
 The project developed into 2 parts
◦ Video Streaming technologies
◦ Database management
 Project can be displayed as a singular website
solution

3. Existing Technologies
 WMP - .asx .asf mms
 Quicktime - .mov .m4v
 Flash - .flv .swf .f4v
 HTTP Pseudo streaming
 Mpeg Part 14 Support (H264/AAC) through flash (.mp4)
 RTMP Streaming – RTMPT (HTTP Proxy)
 VLC’s Plug-in – Java based
 HTML5 <video> Ogg Vorbis, WebM
 Silverlight – IIS Smooth Streaming

4. What Have We been Up To, Eh?
 Website Development
◦ Writing Code:
 Layout through HTLM5 + CSS1/2
 Clientside JavaScript using Google libraries
 Serverside PHP
 Media Automation
◦ Writing Code:
 Automate container migration to mp4
 Extract and convert subtitles to compliant .ttxt/.xml
 Manage metadata for easy library generation

5. Database Talk
 Purpose
◦ Store file information for each file in library
◦ Maintain file structure of database
◦ Cross reference Unique IDs with AniDB
database
◦ Create RSS/XML for each file as necessary
◦ Video specific metadata can be pulled by
FFmpeg libraries
◦ Additional items can be added via text files

6. Database Demo

7. Demo Site
 Stream Server: http://ashbyb.stu.rpi.edu
 Website: http://anime.myrpi.org
 Status: http://ashbyb.stu.rpi.edu/server-status
 Video Pulled Via:
http://anime.myrpi.org/media/query.php?commit=xml
 Other Information Pulled:
http://anime.myrpi.org/media/query.php?commit=time&po
s=1&dur=1&served=1&stats=1

8. Site Issues
 Still to Desired
◦ Utilize a server side database
◦ More Efficient Cross browser compatibility
◦ Less dependency on flash technologies
◦ HTML5 compliant
◦ Mobile Solution
◦ Ability to switch delivery methods

9. Final Thoughts
 Maintain a database to manage many video
files – Tags, Metadata, …
 Present a web fronted library to end-user for
traversal.
◦ Users can add videos to a vote pool
◦ Users can vote on what video to be viewed
 Creates a community-driven vote-based web-
streaming solution.
◦ “It’s like were all watching TV together and voting
on the channel”
 Publish Site Logic
