aviread

Read avi film into matlab on Windows Platform.

Description

Read image frames into matlab from Video (avi) in Windows Platform. Like aviread matlab function. If wmplayer can read your video this function can read too.

Based AVI file reader provided by Microsoft Video for Windows® (VFW)
In visual C++
Header: Declared in Vfw.h
Library: Use Vfw32.lib

-- Depending on your Matlab version, the .mexw32 files may need to be renamed as .dll

-- The library usage is as follows,
mov = aviread(avi_filename, nframes);
image(mov.cdata);

-- recompile the library
I have compiled the code with Visual C++ .net 2003 (ver 7.1)
under matlab tape:

matlab\> mex -setup

Choose your compiler and execute the file mex_cmd.m in archive file for compiling .cpp source files.

• MATLAB release: MATLAB 7 (R14)
• Other requirements: VFW codecs

good and fast

Great, just what I needed. However, line 97 in AviReadMex should be

AviVideo.GetDataImage( ((unsigned char*)mxGetPr(pMxIm)), iNumFrame-1);

as otherwise the first frame is skipped when using one-based indices from matlab.
