Theora is the preferred video codec for the OLPC.

Useful Encoding software

You can encode Theora files using the commmand line application [ffmpeg2theora].

Recommended settings

[This file] plays back well on a B4 laptop, running build 623. Ogg multiplexed audio/video file, Theora/Vorbis, length 1m14s, 320×240 pixels, 148kbps overall.

These settings created a file which played back from the local disk successfully: ffmpeg2theora -x 320 -y 256 -V 148 -A 32 "inputfilename.ogg"

  • [VLC], the free media player software can also encode Theora files.
  • Colinog's wiki contains an entry on how to encode your video in Theora and in Theora/Speex. Translation and walkthrough for this space to come.
