Implementation plan: back

Roadblocks and Challenges:

  • Cannot use opensvcdecoder. Does not support rewriting. Corresponded with the developer Mickael.

Work items

  • Install OpenStack at loacalhost
  • Create VM, Install Darwin Streaming Server or some other open source DASH server
  • User sends request with capability (Howto find user capability?)
  • Document opensvcdecoder? Currently it supports bit stream extraction in command line
  • what about workflows?
    • h.264 AVC multiple resolutions
    • SVC to AVC rewriting: First needs to do a layer extraction using the jsvm tools
      • How to split an SVC stream into single/multiple GoP small files?
    • [Later] SVC layer extraction
    • [other?]

Operational structure

  • Openstack is up an running
  • One front instance is up and running: includes the streaming server or h.264 plugin enabled webserver
  • One storage instance is running. contains all the video
  • front receives request for video, also included is capability info
  • based on capability either:
    • start streamming AVC
    • initiate a distributed stream rewrite opration
      • create writer vms [how many? depends on the video length?]
      • chop and send gops
      • recieve and put together rewritten gops
      • start streaming AVC


Testing

  • A simple html webpage with different resolution/quality video links
  • Onclick plays in embedded player: flowplayer?
  • Apple mobile devices can probably play it too.

References and Links

  • h.264 plugin for web servers? [1]
  • open content with audio and subs etc
    • valkaama: non animation movie in SD, 720p and 1900p [2]
    • Sita sings the blues: full length animated movie in several versions including HD[3]
    • three animated short films: Elephants dream, Big Buck Bunny and Sintel by blender project. available from xiph
