??? Error using ==> aviinfo at 90
Unable to open sample.avi for reading.
Error in ==> aviread>getAviInfo at 439
    info = aviinfo(filename,'Robust');
Error in ==> aviread at 57
info = getAviInfo( filename );
Error in ==> testvideo at 1
avi = aviread('sample.avi');
My system is win7 64bit and when I try to read an avi in matlab errors occur. Could anyone tell me what's wrong?

Best Answer

You should probably heed the warnings about deprecation and use mmreader.m
However, the problem seems more that MATLAB cannot find sample.avi Is this file located in a folder that is on the MATLAB path?
Use addpath() or pathtool to add that folder to the search path.
or pass the full path to aviread
   aviread('c:\data\sample.avi')
Another thing you can if that is not the problem (if the folder containing sample.avi is on the path) is try:
    [fid,msg] = fopen('sample.avi','r','l');
and see what is contained in msg
