The article is about video running on the OLPC laptop. There is also Video of the OLPC project, laptop, etc.

Streaming video over the laptop network

We want to be able to store video on school servers [finding the right address/location], and stream it from them. We want to support recording video from XO to server, viewing video from server to XO (2-min video clips large enough to be buffered on-XO in their entirety) and hopefully streaming video from server to XO (30-minute videos).

Large video files

One large media provider for this test has sent us 600G of video, with more coming tomorrow, for use in countries month. A copy of the video is going to Real, who are trying to get streaming to work as well; but it would be great to have theorur (for instance) working and streaming .ogg for us. Hopefully Juba can be of assistance here.


Video activity

There is a draft activity which records video and can play video back. It doesn't support streaming at the moment, because of troubles getting Theora to stream. MJPEG may be a less computationally intensive choice.

Todo

  1. Get Theora streaming over a school server in a way that works from an XO browser. Talk to Juba about theorur for this.
  1. Figure out how said streaming works with local cache -- if you're streaming an hour-long video, avoiding overwhelming memory or disk.
  1. Define the recommended max size and max bitrate for video (easy if we're not streaming; for streaming, worry about local caching and network throughput.)
