Putting the Software Together

The LCEVC-enabled FFmpeg build can be easily assembled. You will have received software in the following packages:

• FFmpeg: the FFmpeg binaries with support for x264 and x265

• LCEVC: the LCEVC libraries both encoder and decoder libraries

• base codecs: any additional base codecs requested (if applicable)

To set it all up, simply:

1. UnZip the FFmpeg binaries for your operating system into a local directory of your choice (or create a new one). This will be your “FFmpeg directory”.

2. Copy the LCEVC encoder and decoder libraries with their subfolders onto the root FFmpeg directory

3. Copy any additional base codecs and base codec plug-ins that you may have received from their folder onto the root FFmpeg directory (if applicable).

In some cases, for example when installing the LCEVC-enabled FFmpeg build on a clean docker container, you may need to install some or all of the dependencies listed below. Alternatively, installing the generic FFmpeg build may include some of these dependencies.

nasm pkg-config libxml2-dev

Other potential dependencies for an LCEVC-enabled FFmpeg build may include:

dbus libapparmor1 libasound2 libasound2-data libasyncns0 libbsd0 libc6 libdbus-1-3 libexpat1 libflac8 libfontconfig1 libfontenc1 libfreetype6 libgl1 libglvnd0 libglx0 libice6 libogg0 libpng16-16 libpulse0 libsdl2-2.0-0 libsm6 libsndfile1 libuuid1 libvorbis0a libvorbisenc2 libwayland-client0 libwayland-cursor0 libwayland-egl1 libwrap0 libx11-6 libx11-xcb1 libxau6 libxaw7 libxcb-dri3-0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 libxcb-render-util0 libxcb-render0 libxcb-shape0 libxcb-shm0 libxcb-sync1 libxcb-util1 libxcb-xfixes0 libxcb-xinerama0 libxcb-xkb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxdmcp6 libxext6 libxfixes3 libxft2 libxi6 libxinerama1 libxkbcommon0 libxkbfile1 libxmu6 libxmuu1 libxpm4 libxrandr2 libxrender1 libxres1 libxss1 libxt6 libxtst6 libxv1 libxvmc1 libxxf86vm1 xkb-data zlib1g

Quick Tip: For Ubuntu, running sudo apt-get install -y followed by the above dependencies list will install all of them at once.

On Linux systems, especially where more than one build of FFmpeg is available, you may have to set the library path to the local folder for the command to work:

sudo LD_LIBRARY_PATH=.

For further support or to report issues, please reach out to V-Nova through the Download Portal or via [e-mail].

Please note, LCEVC is proprietary to V-Nova and subject to V-Nova's proprietary licence. Therefore, distribution of any pre-compiled subsystem is strictly prohibited, even between group companies.

Additional base codecs

LCEVC can enhance any codec implementation through a simple plug-in system. V-Nova has developed multiple plug-ins for the most popular base codec implementations. These can be requested and will be packaged as part of a release in a separate base codecs folder. The folder will include:

• the base codec plug-ins

• (optionally) the base codec libraries

The content of the above folders needs to be copied into the root FFmpeg directory
