    Compiling and Installing FFmpeg with Decklink Support and Nvidia Cuda on Ubuntu Server

1. Download and Install the NVIDIA Driver

Install the NVIDIA driver for CUDA and other GPU-related tools:

Version: nvidia-driver-535

sudo apt update
sudo apt-get install nvidia-driver-535
sudo reboot

2. Install the NVIDIA CUDA Toolkit

sudo apt-get install nvidia-cuda-toolkit

3. Get NVIDIA Video Codec SDK

Download and set up the NVIDIA Video Codec SDK:

Version: Video_Codec_SDK_11.1.5

mkdir -p ~/ffmpeg_sources ~/bin
cd ~/ffmpeg_sources && git clone https://github.com/LuizStSantos/Video_Codec_SDK_11.1.5.git NV_Codec_SDK
mkdir -p ~/ffmpeg_sources/NV_SDK
cp -r NV_Codec_SDK/Interface ~/ffmpeg_sources/NV_SDK

4. Download and Install the DeckLink Driver

Download the Desktop Video driver and Desktop Video SDK from the official Blackmagic website:

Download Desktop Video and SDK
Version: Blackmagic_Desktop_Video_Linux_14.0.1

tar -xf Blackmagic_Desktop_Video_Linux_*.tar
cd Blackmagic_Desktop_Video_Linux_*/deb/x86_64/
sudo dpkg -i desktopvideo_*.deb
sudo apt-get install -f
BlackmagicFirmwareUpdater status
# If prompted to update the firmware, perform the update
BlackmagicFirmwareUpdater update 0
# If prompted to reboot, reboot the system
sudo reboot

5. Install the Desktop Video SDK


Version: Blackmagic_DeckLink_SDK_14.0

sudo apt install unzip
unzip Blackmagic_DeckLink_SDK_*.zip
cp -r Blackmagic\ DeckLink\ SDK\ */Linux/ ~/ffmpeg_sources/BMD_SDK

6. Install Dependencies for Compiling FFmpeg

sudo apt-get update -qq && sudo apt-get -y install \
  autoconf automake build-essential cmake git-core \
  libass-dev libfreetype6-dev libgnutls28-dev libmp3lame-dev \
  libtool libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev \
  meson ninja-build pkg-config texinfo wget zlib1g-dev libharfbuzz-dev \
  libfontconfig-dev libfribidi-dev libzmq5-dev
For audio and video encoding:
sudo apt-get -y install nasm yasm libx264-dev libx265-dev \
libnuma-dev libvpx-dev libunistring-dev libfdk-aac-dev \
libmp3lame-dev libopus-dev libssl-dev libdav1d-dev

7. Compile and Install Additional Dependencies (ffnvcodec, libsrt, SVT-AV1)

ffnvcodec:

Version: On Videolan

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

Version: On Github

cd ~/ffmpeg_sources
git clone https://github.com/Haivision/srt.git
cd srt
./configure
make -j$(nproc)
sudo make install
cd
SVT-AV1:

Version: SVT-AV1-v2.2.0

cd ~/ffmpeg_sources
wget https://gitlab.com/AOMediaCodec/SVT-AV1/-/archive/v2.2.0/SVT-AV1-v2.2.0.zip
unzip SVT-AV1-v2.2.0.zip
cp -r SVT-AV1-v2.2.0 ~/ffmpeg_sources/SVT-AV1
cd SVT-AV1
mkdir build
cd build
cmake .. -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
sudo make install
cd

8. Download FFmpeg Source Code


Version: ffmpeg-7.0

cd ~/ffmpeg_sources
wget -c https://ffmpeg.org/releases/ffmpeg-7.0.tar.bz2
tar -xvf ffmpeg-*.tar.bz2
cd ffmpeg-*/

9. Configure FFmpeg to Support DeckLink

Configure FFmpeg with the necessary options for DeckLink and other codecs:
PATH="$HOME/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/cuda/lib64:/usr/local/lib:/usr/lib:/lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib/pkgconfig:$PKG_CONFIG_PATH"

./configure \
  --prefix="$HOME/ffmpeg_build" \
  --pkg-config-flags="--static" \
  --extra-cflags="-I$HOME/ffmpeg_build/include -I$HOME/ffmpeg_sources/BMD_SDK/include -I/usr/local/cuda/include -I$HOME/ffmpeg_sources/NV_SDK/Interface" \
  --extra-ldflags="-L$HOME/ffmpeg_build/lib -L/usr/local/cuda/lib64 -L$HOME/ffmpeg_sources/NV_SDK/Lib/linux/stubs/x86_64" \
  --extra-libs="-lpthread -lm" \
  --ld="g++" \
  --bindir="$HOME/bin" \
  --enable-gpl \
  --enable-libass \
  --enable-libfdk-aac \
  --enable-libfreetype \
  --enable-libharfbuzz \
  --enable-libfontconfig \
