Abstract
Techniques are provided which allow computers with relatively less computational power to perform dynamic conversion of video from inter-frame dependent format to an independent-frame format while playing the video as it is being converted. If the conversion operation is not keeping up with the arrival of the incoming video, the video is spooled within the computer system. The playback and conversion operations proceed as the spooling is performed. Thus, to a viewer of the video, the video may appear to slow, but the playback and conversion operation proceed without losing frames.
