I am reading the attached video with Matlab R2021a, but I get an empty matrix result. However, this video can be played with PotPlayer or read by python code.
Matlab code:
file = VideoReader('tmpGetStiTimeFromFrametest.mov');
frm = read(file);

Hi,
I tried to read the frames from the provided video but it seems there is some issue with the videofile itself. I also tried to open that in my Desktop but the video was not playing. You can try checking the videofile again and use the read().
At my end I used an example ".mov" videofile and it was working fine, attaching that here for your reference.
v = VideoReader("example.mov");
frm = read(v);

VLC is displaying at a lot larger than 6 x 8, and VLC is interpolating somehow.
That is, VLC knows the proper size of the video, but when it displays it in a larger window, it is not just replicating pixels; it is interpolating to a larger size when it displays. This is an issue with VLC.
