Compiling OpenCV with ffmpeg GPU support

edit

i am trying to get FFMPEG to use GPU to improve the speed of my program. I got FFMPEG from cloning https://git.ffmpeg.org/ffmpeg.git and followed the steps here https://developer.nvidia.com/ffmpeg to get it working.

I am building opencv 3.1.0 by cloning, git clone https://github.com/opencv/opencv.git and using git checkout -b v3.1.0 3.1.0. I also had to cherry pick some git commits to make this working properly.

When I bulid Opencv; -- Video I/O: -- DC1394 1.x: NO -- DC1394 2.x: NO -- FFMPEG: YES -- codec: YES (ver 58.20.103) -- format: YES (ver 58.17.100) -- util: YES (ver 56.18.102) -- swscale: YES (ver 5.2.100) -- resample: NO -- gentoo-style: YES

When I run ffmpeg on the terminal:

ffmpeg version N-91329-g830695b Copyright (c) 2000-2018 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.9) 20160609 configuration: --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 libavutil 56. 18.102 / 56. 18.102 libavcodec 58. 20.103 / 58. 20.103 libavformat 58. 17.100 / 58. 17.100 libavdevice 58. 4.101 / 58. 4.101 libavfilter 7. 25.100 / 7. 25.100 libswscale 5. 2.100 / 5. 2.100 libswresample 3. 2.100 / 3. 2.100

However, when I run make -j15, I get an error:

Any help would be greatly appreciated.
