• Cài đặt NVIDIA-SDK (Cài đặt trước khi compile ffmpeg)

     cd ~/ffmpeg_sources && \ 
     git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git && \
     cd nv-codec-headers && \
     make install
  

• Trong file setup ffmpeg thêm vào biến CUDA_DIR="/usr/local/cuda" dẫn tới thư mục install CUDA,
• Dòng 77 --extra-cflags="-I$HOME/ffmpeg_build/include" \ đổi thành --extra-cflags="-I$HOME/ffmpeg_build/include -I$CUDA_DIR/include/" \
• Dòng 78 --extra-ldflags="-L$HOME/ffmpeg_build/lib" \ đổi thành --extra-ldflags="-L$HOME/ffmpeg_build/lib -L$CUDA_DIR/lib64/"
• Thêm vào các option sau trong configure ffmpeg:
  --enable-cuda \
--enable-cuda-nvcc \
--enable-cuvid \
--enable-libnpp \
--enable-nvenc \

* Cài đặt NVIDIA-SDK (Cài đặt trước khi compile ffmpeg)
  ```
     cd ~/ffmpeg_sources && \ 
     git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git && \
     cd nv-codec-headers && \
     make install
  ```

* Trong file setup ffmpeg thêm vào biến `CUDA_DIR="/usr/local/cuda"` dẫn tới thư mục install CUDA,

* Dòng 77 `--extra-cflags="-I$HOME/ffmpeg_build/include" \` đổi thành `--extra-cflags="-I$HOME/ffmpeg_build/include -I$CUDA_DIR/include/" \`

* Dòng 78 `--extra-ldflags="-L$HOME/ffmpeg_build/lib" \` đổi thành `--extra-ldflags="-L$HOME/ffmpeg_build/lib -L$CUDA_DIR/lib64/"`

* Thêm vào các option sau trong configure ffmpeg:
  `--enable-cuda \`
  `--enable-cuda-nvcc \`
  `--enable-cuvid \`
  `--enable-libnpp \`
  `--enable-nvenc \ `
