This means that if you are a user of previous Audacity versions on Mac and had installed the optional FFmpeg library then you must now install the 64-bit versions of the FFmpeg library, otherwise your imports and exports that depend upon FFmpeg will no longer work.

Audacity ManualĪs it appears to be possible to still compile Audacity with newer FFmpeg releases for file format conversions not natively supported by Audacity. In these packaged builds there is no need to locate LAME or FFmpeg, so Audacity will have no "Libraries" Preferences. Some Linux distributions (for example, Ubuntu) now package Audacity with MP3 encoding and FFmpeg support already linked dynamically to the relevant system libraries. Audacity is already compiled and built against libavcodec and LAME: This will conflict with older libavcodec releases. Audacity Manualįrom 14.04 we will have installed libavcodec54 by default. It may not currently be possible to build Audacity against later versions of FFmpeg. From the Audacity manual we can read that it will not build against FFmpeg libraries newer than 0.8:Īudacity should support building against FFmpeg 0.5 through 0.8.
