make produces the error:

gcc -O3 -fopenmp -c -fpic -Wall -I. -I/usr/local/include video_decoder.c video_decoder.c:13:18: fatal error: luaT.h: No such file or directory

include 

              ^

compilation terminated. make: *\ [video_decoder.o] Error 1

@jrbtaylor The old Makefile is updated via https://github.com/e-lab/torch-toolbox/commit/36151e011db9499e27a4d6c9c0a83f751ce104a4 . Could you try again if the problem still exist? Make sure to check your Torch is installed in $(HOME)/torch, otherwise manually change the environment variable TORCH in the Makefile.

Thanks. Make now works but I am getting an error on local video = assert(require("libvideo_decoder"))

@jrbtaylor You may want to update your libav library because avcodec_alloc_frame is deprecated and replaced by av_frame_alloc. Or change all av_frame_allocs to avcodec_alloc_frame manually in the source and see if it works.
