Matlab（Linux）：mp4视频加载

Question

I'm trying to load an mp4 video with Matlab with:

  robj=VideoReader('ball moving.mp4')

I receive the following error:

Error using VideoReader/init (line 450)

The VideoReader plugin libmwgstreamerplugin failed to load properly.

Error in VideoReader (line 147)

obj.init(fileName);

Matlab (R2013a) is running on a Linux machine (Ubuntu 14.04.2 LTS). Something is wrong in the installation, but what is it?

Answer 1

Downgrading gstreamer packages from version 1.0 to 0.10 "solved" the issue. Maybe because package gstreamer-x-ffmpeg is required (only found for version x=0.10, in ppa:mc3man/trusty-media ).

Answer 2

Install ffmpeg and use this function:

function v=readVideo(path_file)

system(['rm /tmp/video_tmp.avi']);
system(['ffmpeg -i ' path_file ' -vcodec copy -acodec copy /tmp/video_tmp.avi']);

v = VideoReader('/tmp/video_tmp.avi')

end
