Private:cloud svc

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.
