Video

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.)
