VivoActive is an audio/video format created by Vivo Software, acquired by RealNetworks in 1997. The Vivo format is based upon H.263 video and G.723 ADPCM audio (not the G.723.1 speech codec). It uses inter-frame coding, but does not insert any key frames, except at the beginning of the clip, which effectively disables the possibility of seeking to specific locations in the stream. One of the last released versions of VivoActive Player added a workaround for this handicap by quickly decoding all frames from the first one to the requested position.

MPlayer is able to play and convert Vivo video clips.
