A wrapper and install guide for CUDA-accelerated FFMPEG decoding in OpenCV

FFMPEG w/ NVENC & CUDA Support

1. Dependencies:

   • Have CUDA / CUDNN already working (10.2 req'd on driver 440 as of writing)
   • YASM: sudo apt-get install yasm

2. Clone the FFMPEG git repo: git clone https://git.ffmpeg.org/ffmpeg.git

3. cd ffmpeg

4. ./configure --enable-cuda-sdk --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64

5. make (this may take a while, go get some coffee 🙂)

6. make install

7. Test using ffmpeg -y -hwaccel cuvid -c:v h264_cuvid -vsync 0 -i <input.mp4> -vf scale_npp=1920:1072 -vcodec h264_nvenc <output0.264> -vf scale_npp=1280:720 -vcodec h264_nvenc <output1.264>
