aviread - Read Audio/Video Interleaved (AVI) file

Note   aviread is not recommended. Use mmreader to read various video file formats, including AVI.

Syntax

mov = aviread(filename)
mov = aviread(filename, index)

Description

mov = aviread(filename) reads the AVI movie filename into the MATLAB movie structure mov. If filename does not include an extension, then .avi is used. Use the movie function to view the movie mov. On UNIX platforms, filename must be an uncompressed AVI file.

mov has two fields, cdata and colormap. The content of these fields varies depending on the type of image.

Image Type	cdata Field	colormap Field
Truecolor	Height-by-width-by-3 array of uint8 values	Empty
Indexed	Height-by-width array of uint8 values	m-by-3 array of double values

aviread supports 8-bit frames, for indexed and grayscale images, 16-bit grayscale images, or 24-bit truecolor images. Note, however, that movie only accepts 8-bit image frames; it does not accept 16-bit grayscale image frames.

mov = aviread(filename, index) reads only the frames specified by index. index can be a single index or an array of indices into the video stream. In AVI files, the first frame has the index value 1, the second frame has the index value 2, and so on.
