A = VideoReader('Augthirtycm.mp4');
n=A.NumFrames;
%Above is my simple code but when I run code it is showing error like below
No appropriate method, property, or field 'NumFrames' for class 'VideoReader'.
Error in frmaes (line 2)
n=A.NumFrames;
is there any alternative command for finding total number of frames in my video in r2015a version

It used to be NumberOfFrames: https://www.mathworks.com/help/releases/R2015a/matlab/ref/videoreader-class.html#properties
n=A.NumberOfFrames;

Look down in the Limitations of the current documentation:
- For some AVI, MOV, or MP4 files on Windows®, using the readFrame function to read all of the frames in the file can result in a different number of frames than the value returned by the NumFrames property of the VideoReader object.
The NumFrames count is not exact.
