I am trying to read a h264 video in Matlab Ubuntu 14.10 using VideoReader, and i get an error.
"Could not read file due to an unexpected error. Reason: Unable to initialize the video obtain properties"
Error in VideoReader (line 172)
obj.init(fileName);
I have the codecs installed as i can play the file from Ubuntu player. Does some one experienced some thing like that. By the way the files are from GoPro and Android camera.

Exactly the same error. It seems wierd that the error is in line 617 of VideoReader,
try
obj.VideoReaderImpl = audiovideo.mmreader(fullName);
catch exception
VideoReader.handleImplException( exception );
end
But audiovideo.mmreader(fullName) is a deprecated object. Indeed:
function obj = mmreader(fileName, varargin)
error(message('MATLAB:audiovideo:mmreader:mmreaderToBeRemoved'));
end

ffmpeg had removed repo of Ubuntu, instead of libav. you should add ppa:
sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg gstreamer0.10-ffmpeg

sudo apt-get install libgstreamer0.10-dev gstreamer-tools gstreamer0.10-tools gstreamer0.10-doc
sudo apt-getinstall gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse
At last,restart.

Should the "apt-getinstall" in the second line be two words like it is on the first line?
