Hello all,
I would like to try the code from MATLAB's own documentation, but I ran into a problem. I think the documentation has a problem and I can't find where I'm reporting it. Can someone help me for report it and make it up and running?

What difficulty are you encountering?
Note: you need to download the HMDB files yourself.

I'm getting "Index must not exceed 0" in 5th line but the array is numbering as 1 already in 4th line.

You have not downloaded and extracted the HMDB files. You need to download the .rar file and extract it, which will give you a directory with a number of .rar files. You have to extract all of those too.

On my Mac, I run into a different problem,
Error using VideoReader/initReader
Could not read file due to an unexpected error. Reason: Cannot Decode
Error in audiovideo.internal.IVideoReader (line 136)
initReader(obj, fileName, currentTime);
Error in VideoReader (line 104)
obj@audiovideo.internal.IVideoReader(varargin{:});
Error in ClassifyVideosUsingDeepLearningExample>readVideo (line 135)
vr = VideoReader(filename);
This is because the vidoes are encoded with the DX50 encoder from DivX, which is not normally supported on Mac.
