The xo-1 did not seem to have the processing power to successfully encode
video and audio simultaneously. The resulting videos were very choppy when
played back (both video and audio).
The xo-1 also did not have enough drive space (or speed?) to hold large
amounts of uncompressed video.
Therefore, the video was encoded on-the-fly, and the audio was saved
directly to disk (uncompressed audio takes up less space than the
The final step was to mux and encode the audio into one file.
I suspect a similar solution for video with synchronized audio might be
required for other netbooks with limited hardware resources.
I am not sure how the sugar team plans to target activities to different
- download record-notebook-61.xo or record-netbook-61.xo ?
- activity-authors query the system for flags about the hardware's
capabilities and in the case of record use a different set of pipelines?
