Subject: [PATCH] The part of the code that should get the config that is used
 to get the constraints of the GPU is now inside a #if . One can enable it by
 setting the constant in line 33 of FFmpegReader.cpp to 1. Do not enable that
 part unless you want to fid a way that works as it also needs the package
 libva-dev (Ubuntu) to be installed.
