Hi all,
The object created using VideoReader function in matlab does not show the NumberOfFrames.
Referring to https://de.mathworks.com/matlabcentral/answers/250033-number-of-frames-in-video-file-with-matlab-2015b
This could be because of the variable frame rate.
The Number of frames can be estimated:
vidObj = VideoReader('myfile.MOV');
numFrames = ceil(vidObj.FrameRate*vidObj.Duration);
In My algorithm I needed to pick a particular frame, so I decded to export all frames as picture using:
vidObj = VideoReader('myfile.MOV');
numFrames = 0;
while hasFrame(vidObj)
readFrame(vidObj);
numFrames = numFrames + 1;
end
But after 14000 frame has been exported I encountered the following error:
What could be possible reason for this error? or skip this particular frame
How could this be fixed??
Thank you very much for your suggestions and help in advance.
