Video IO toolbox for matlab. 用directshow做的

function disp(vr)
%DISP(vr) displays a videoWriter object without printing its name.

ctor = class(vr);

% merge Matlab-side and plugin-side metadata
einfo = struct(vr);

fnames = fieldnames(info);
for i=1:length(fnames)
  fname = fnames{i};
  einfo.(fname) = info.(fname);
end

% make pretty plugin name...the way the constructor expects it
if isfield(einfo, 'plugin') && strmatch([ctor '_'], einfo.plugin) 
  einfo.plugin = einfo.plugin(length(ctor)+2:end);
end

% actual display
disp(['  ' ctor ' object']);
if ~isequal(get(0,'FormatSpacing'),'compact')
