这个bug卡了半天，这里记录一下
Error using VideoReader/init (line 619) 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);
环境：Ubuntu16.04
首先安装gstreamer0.10-ffmpeg
1 sudo add-apt-repository ppa:mc3man/gstffmpeg-keep 2 sudo apt-get update 3 sudo apt-get install gstreamer0.10-ffmpeg
重启MATLAB，如果像我一样还是报错，别慌，继续安装codecs(解码器)
sudo apt install ubuntu-restricted-extra
问题解决
MATLAB读视频报错 Unable to initialize the video obtain properties (videoreader in Matlab)
