Variable frame number in 2 different machines
显示 更早的评论
vidObj = VideoReader('video_file.avi');
numFrames = 0;
while hasFrame(vidObj)
readFrame(vidObj);
numFrames = numFrames + 1;
end
numFrames
I am getting a variable numFrames (number of frames) in running the same code on two different machines
i.e. I am reading the number of frames using the above code snippet in two separate machines both with Matlab2017 installed, on the same video file. However, I am getting two different values of frame numbers on each machine. Could you please let me know why that is so?

Hereby attaching the results from multiple workstations. It is not like it alters between every machine. There is a discrepancy in select few machines, the cause of which is what I am trying to understand here.
FYI > Everything is the same in both systems except that in my laptop its matlab2017b and in my workstation its matlab2017a if that helps

Hi, are you able to provide an example file which you are noticing this issue with?
What operating systems are you using on the machines which you are testing this on?

I suggest using VLC to transcode the file. I suspect that it is either corrupt or uses some video feature that was not available in Windows 7 readers.
