Our lab have a eye-tracking glasses which can record environment that the subjects are facing, and generates .avi video file. The file can be played by VLC player directly. However, when I try to read the video file into Matlab R2017a for further analysis, it seems that I can't get video frames out of the file.
First I create a VideoReader object by:
vidReader = VideoReader('EyeTrackerVideo.avi');
And the "vidReader" correctly reports my video duration, framerate, height and width. However, when I type
hasFrame(vidReader)
It returns "0", which prevents me from reading frames in my video file, according to matlab documentation.
What is the cause of this problem? Is there any other way I can read frames out of my video file?
