Video IO toolbox for matlab. 用directshow做的

function images = doFullRead(varargin)
%IMAGES=DOFULLREAD(...)
%  Reads in an entire video into a 3D array where only the red channel is 
%  retained (just to make it easier).
%
%  Any arguments given are passed directly to the videoReader constructor.
%
%Examples:
%  imgs = doFullRead;
%  imgs = doFullRead('ffmpegPopen2');  % linux & similar
%  imgs = doFullRead('ffmpegDirect');  % ...if system's gcc is compatible w/ Matlab's
%  imgs = doFullRead('DirectShow');    % Windows
