When MuViPlayer is used for connecting to MuViServer, there are some extra features enabled: Terminal Capabilities of the client (like grayscale display or only a certain resolution like QCIF is possible) but also adaptive streaming and retransmission of important packets. Further, this is a MultipleVideoPlayer, so one might open videos from various servers in various different qualities and also from local sources for comparison or eg. surveillance issues. Displaying is done using SDL and ffmpeg or xvid.
