'''Programming Languages and Libraries'''
Since sugar-chat-activity uses Python, I will likely be using it for this project as well. The GStreamer libraries will be used for communicating with the Icecast server and uploading multimedia. Ogg will probably be used as the container, Theora will be used as the video codec, and Vorbis will be used as the audio codec, since this is a relatively well-supported combination (supported for in-browser playback on upcoming browsers) and poses no licensing issues, though thanks to the flexibility of GStreamer any other supported codecs and container could alternatively be used.

As XOs do not apparently have enough cpu power to encode Theora video live at acceptable resolution and framerates, older, less cpu-intensive codecs, such as MPEG-1, MJPEG, or H.261 may be used as video codecs instead.
