Using this Guideįollowing this guide in its entirety will build a static FFmpeg installation with external libraries such as fdk-aac, libopus, x265 and the SOX resampler. After this, we'll be compiling the remaining packages, before using a combination of both to compile FFmpeg itself.
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 use Cygwin to compile FFmpeg with better external libraries? I already have Cygwin available on my machine, and I'd rather use that to compile the program rather than setup another software ecosystem or burn a whole Linux distribution. 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, due to licensing reasons, the pre-compiled Windows executables of FFmpeg come out of the box 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
