When running these lines, I am geting the error "Expected index to be positive." and cannot figure out why.
vfull = VideoReader('LLZO0024-04-21-24.MP4');
%specific sections to read
section1 = read(vfull,[0 5]);
section2 = read(vfull,[10 15]);
section3 = read(vfull,[20 25]);

It is because indexing in matlab starts from 1 and not from 0
Changing line 3 to this:
section1 = read(vfull,[1 5]);
will solve this error
