when I configure the Torch Video Decoder Library, it appears an error, My steps to configure the environment are as follows：
$ sudo add-apt-repository ppa:mc3man/trusty-media
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo apt-get install ffmpeg
$ luarocks install ffmpeg
sudo apt-get install -y libavformat-dev libavutil-dev libavcodec-dev libswscale-dev libfreetype6-dev
then I go to torch-toolbox/Video-decoder/ and make, it appears an error, and I do not know how to solve it:

How did you solve the problem? When I run th run_pred-feat_twoStreams.lua it gives me the following error
