VideoReader don't read .m4v

Hello there, I was using VideoReader to read a .m4v file on my Windows 10 education. But there comes the following error:

Error using VideoReader/init (line 619) Could not read file due to an unexpected error. Reason: Error Creating Source Reader Reason: The byte stream type of the given URL is unsupported.

Error in VideoReader (line 172) obj.init(fileName);

Does any one know how can I fix this?

My matlab version is R2017b. I used VideoReader to read .avi and works. I can open the .m4v video with VLC player but not windows media player. I tried to install gstreamer1.0 but not work.

Many thanks for your reading.

Both Windows Media player and videoReader support the m4v format. Since VLC is able to play but Windows Media Player is not, it looks like it is a codec issue. Please download the latest compatible version of codec from https://www.mediaplayercodecpack.com/ and try again.

Thanks very much to your answer. This method fixed the problem of windows media player. But matlab still can't read the .m4v movie with the same error message. So far my method to work around is to extract the images from the .m4v movie by using ffmpeg and then read each images separately from matlab.

Worked great for me (2020a), thanks Harish!
