To compile the x264 video codec: cd /ffmpeg_sources & rm -rf x264 & To compile the LAME audio codec for MP3: cd /ffmpeg_sources & rm -rf lame-svn & This is the directory we'll be downloading our source code to, and compiling it from. If you decide you don't require your build of FFmpeg to support a given library, skip its section and remove the corresponding -enable- package line when compiling FFmpeg in the final stage of this guide.Ĭreate a directory at the root of your Cygwin installation with the following: rm -rf /ffmpeg_sources & Copy and paste the whole of each command into your shell. Mingw64-x86_64-windows-default-manifest \Įach section below compiles an external library that will allow you to compile FFmpeg with support for that library enabled. Install build tools and set up the MinGW-w64 cross-compiler apt-cyg install \ Ln -s "$(realpath apt-cyg/apt-cyg)" /usr/local/bin/ To install kou1okada's apt-cyg: mkdir -p /usr/local/src & If you don't currently use a package manager for Cygwin, this step will not only make the rest of the guide a breeze, but will also make your Cygwin experience rival that of any Linux distribution.Įven if you already use a package manager for Cygwin, such as a different fork of the original apt-cyg, I highly recommend you replace it with this one, which is a much more fully-fledged piece of software compared to the original, as well as the only package manager for Cygwin that is currently in active development. Next, install kou1okada's fork of the apt-cyg package manager. The good news is that these packages are dependencies for a tool that can prevent you from ever needing to use the Cygwin installer again. To begin with, download the latest version of the Cygwin installer to install the wget, tar, gawk and git packages. This location also has the secondary advantage of being on the system PATH by default in Cygwin, and so doesn't require the $PATH environment variable to be updated. FFmpeg will be installed to /usr/local, where the FHS standard recommends that software compiled by the user is installed to. This guide will create a folder in your Home directory called ffmpeg_sources, where it will download and compile all of the packages being built from source. The installation itself, made up of the binaries and documentation, occupies just over 200MB of disk space. The dependencies used by this guide - made up of the MinGW-w64 cross-compile toolchain itself, all packages installed by apt-cyg and all packages compiled from source - will consume up to 2.8GB of disk space, although the guide also includes commands to clean up everything but the FFmpeg installation once done. I may consider adding instructions for compiling specific external libraries to the guide if I get enough requests to do so for a particular library. After this, we'll be compiling the remaining packages, before using a combination of both to compile FFmpeg itself.įollowing this guide in its entirety will build a static FFmpeg installation with external libraries such as fdk-aac, libopus, x265 and the SOX resampler. Thankfully, this is as easy as installing a few packages. the gcc-core package included with the Cygwin installer) is inherently broken for cross-compiling purposes, and there doesn't seem to be any intent from the Cygwin maintainers to fix this, so currently, the only way to compile software for Windows with Cygwin is to set up a MinGW-w64 toolchain under it. Unfortunately, Cygwin's default toolchain (i.e. This is easier said than done, and has taken me over a month to figure out how to do without any issues, but I've spent enough time on it that I decided I'd document the process well enough to be completed virtually seamlessly by anyone following me. How can I compile FFmpeg with better external libraries on Cygwin/Windows? If you want FDK-AAC you have to compile handbrake yourself. enable-nonfree if you're also using -enable-gpl). Requires ffmpeg toīe configured with -enable-libfdk-aac (and additionally Highest-quality AAC encoder available with ffmpeg. This canīe resolved by compiling ffmpeg yourself. Therefore this encoder have been designated as "non-free",Īnd you cannot download a pre-built ffmpeg that supports it. The license of libfdk_aac is notĬompatible with GPL, so the GPL does not permit distribution ofīinaries containing incompatible code when GPL-licensed code is also It's generally accepted that, by default, FFmpeg comes packaged with lower-quality encoders - particularly when it comes to the default AAC encoder and the default resampler.Īccording to these sources, the solution is to compile the program from source:įFmpeg supports two AAC-LC encoders (aac and libfdk_aac) and one
