FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

For Jellyfin

This particular repository is designed to support building a static, portable, FFMPEG release of 4.0.3 for the Jellyfin project.

To build packages, use ./build <release> <arch>, where release is one of:

• stretch (Debian 9.X "Stretch")
• buster (Debian 10.X "Buster")
• xenial (Ubuntu 16.04 "Xenial Xerus")
• bionic (Ubuntu 18.04 "Bionic Beaver")
• cosmic (Ubuntu 18.10 "Cosmic Cuttlefish")

And arch is one of:

• amd64 (Standard 64-bit x86)
• armhf (ARMv6, Raspberry Pi)

The build setup requires docker support and may use a significant amount of disk space. Binary releases are available in the repository.

For older Ubuntu releases in between these officially supported versions, the oldest should generally be compatible.

The build setup will attempt to generate both amd64 and armhf binary packages if the release supports it.

Libraries
