I installed the latest GStreamer plugins on my Fedora14 64 bit machine to read a video. I can read this video with totem but when I try to read it with 'VideoReader' in MATLAB I get an error message:

 ??? The file requires the following codec(s) to be installed on your system:
 video/mpeg
 Error in ==> VideoReader.VideoReader>VideoReader.init at 423
             obj.VideoReaderImpl = audiovideo.mmreader(fullName);
 Error in ==> VideoReader.VideoReader>VideoReader.VideoReader at 133
             obj.init(fileName);

The same thing happen when I try to get informations on this video file with 'mmfileinfo', but the 'aviinfo' function works well and the 'VideoCompression' field is 'FMP4'

I get the same error on Ubuntu 64 bit.
