 Ogg Theora and WebM (encouraging their use)
In the field of audio-video software, the situation is so bad that rather than avoiding some danger areas, the whole field is in danger so we have to encourage the use of a small number of project specifically targeting freedom from patents.
The project with the best chance of success is WebM, based on the VP8 video format. Another project we support is Ogg Theora. There is one other option: H.261. H.261 was developed in 1988, so it is guaranteed to be patent free. However, due to the low quality of this old format, its use has almost no support. (See: Use software from 20 years ago)
