Hi,
I am reading every 600th frame from the video by using the end operator but I am getting this error here.
Code:
v = VideoReader('DSC_1191.MOV');
frame = read(v,[600:600:end]);
Error:
The end operator must be used within an array index expression.
Error in Spec_Frame (line 3)
frame = read(v,[600:600:end]);

请先登录，再回答此问题。

See the original question - i fixed the error.
frame = read(v,[600:600:end]);
will not work in this case.

In this case read is a function, not a variable. Attempting to "index" into the function with end won't work. I would probably replace end with v.NumFrames.
