MATLAB: Does AVIINFO function support AVI 2.0 in MATLAB 7.3

MATLAB

I executed AVIINFO command to an AVI file which is in AVI 2.0 format. The function reported a few less NumFrames than actual frame numbers.

I want to know if AVIINFO function supports the AVI2.0 format.

AVI 2.0 is just another unofficial name for OpenDML. To learn more about OpenDML(AVI 2.0) review the wikipedia below using the following URL:

AVIINFO does not support OpenDML files which is required to read large AVI files.

As a workaround, you might consider using MMFILEINFO function.

MATLAB: When using AVIREAD and AVIINFO, why do I receive a warning that the function will be removed in a future release in MATLAB 7.10 (R2010a)

This enhancement has been incorporated in Release 2010a (R2010a). For previous product releases, read below for any possible workarounds:

AVIREAD and AVIINFO are being deprecated, and users should now use the functions MMREADER and MMFILEINFO.

MMREADER creates a filereader object, and frames from the object may be accessed using MMREADER/READ method. MMFILEINFO returns an information about the multimedia file.

MMFILEINFO has a very similar syntax to AVIINFO.

info = mmfileinfo('example.avi')

When using MMREADER, an mmreader object is created an the data is accessed via MMREADER methods.

% Create reader object
obj = mmreader('example.avi')
% Get information about the object
get(obj)
% Read the first frame of the object
obj.read(1)
% Create object and read first frame all in one line
read(mmreader('example.avi'),1)

MATLAB: Do I get “Error using ==> aviinfo (errorWithFileClose)” when trying to import a file using AVIREAD with MATLAB 6.0 or 6.1

This problem has been fixed in MATLAB 6.5 (R13).

If you are using MATLAB 6.1 (R12.1) or an earlier version, see the information below.

This problem seems to have to do with the formatting of the particular AVI file. One solution is to import it into a third party .avi editing application and then export it again. If the formatting that was causing the problem is changed, then the file will be able to be imported into MATLAB.
