function vbbPlayer( s, v )
% Simple GUI to play annotated videos (seq files)
%
% Uses the seqPlayer to display a video (seq file). See help for the
% seqPlayer for navigation options (playing forward/backward at variable
% speeds). Note that loading a new video via the file menu will not work
% (as the associated annotation is not loaded). The location of the videos
% and associated annotations (vbb files) are specified using dbInfo. To
% actually alter the annotations, use the vbbLabeler.
%
