Error reading mp4

Subject: Error reading mp4

Hello,

I am having some problems opening an mp4 file in Matlab (7.13.0.564 (R2011b) 64 bit, Windows 7).
mminfo gives this error error "Could not get file information. System error: Impossible de lire le fichier. Le format n’est pas pris en charge". (I have Windows 7 in French, it means means "cannot read the file, the format is not handled").
VideoReader says "The file requires the following codec(s) to be installed on your system: Unknown Codec".

The video plays fine in VLC and Windows Media (v 12); the codec is called "H264 - MPEG-4 AVC (part 10) (avc1)" in VLC.

Thanks for any help!
Claudio

Did you solve this issue? I'm having the same problem with the same codec and I can't find a way around it...

Hello Jorge,

No, I could not solve it. I work around the problem by piloting VirtualDub from Matlab through scripts; I export the video in JPG or BMP frames and work on them.

Good luck!

Claudio

Hello, I solved this problem installing the K-Lite Codec Pack to my computer.

Unfortunately, I already had K-Lite installed on my computer!
I still haven't found a proper solution.

Cheers,
Claudio
