MATLAB读视频报错 Unable to initialize the video obtain properties (videoreader in Matlab)

Posted 2021-01-27 demian

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

参考：stackoverflow

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
