error coming :

error reading video file.

please solve issue.

the problem quite clear capvideo.open("c:\users\sbv\documents\myvideo.avi");

you try open myvideo.avi in path: 

c:\\users\\sbv\\documents\\myvideo.avi

but file not exist @ path.

quick fix: work in cygwin

capvideo.open("c:/users/sbv/documents/myvideo.avi");

or put myvideo.avi in same directory program.
