Shared build results in a few libraries (and these libraries may depend on other non-FFmpeg libraries), each library exports different functions. Static build results in one big library, that contains all functions from FFmpeg package. It's not yet clear which build of FFmpeg will be used - static or shared. This allows FFmpeg to be optional (Audacity will run without FFmpeg) and it could be distributed separately (removes licensing issues). Note that details of the documentation or of the project implementation itself may change over time.Īs a design decision, FFmpeg libraries are being linked dynamically and loaded at run time. User documentation was produced by the student and has been incorporated into appropriate pages in the Audacity Manual. While FFmpeg also has other uses, this is outside the scope of this project. In Audacity FFmpeg will be used to import and export audio data. 4.1 Importing and Exporting using the Audacity-recommended version of FFmpegįFmpeg is a set of libraries for audio/video encoding/decoding/muxing/demuxing/processing/capturing.to see diagnostic information about FFmpeg detection. You can also choose Help > Diagnostics > Show Log. button to obtain the correct library for your operating system. If you still see 'not found', you may have installed the wrong libraries. Note that the FFmpeg library has been locatedįFmpeg Library Version should now show a set of three version numbers for the sub-libraries of FFmpeg ('F' for libavformat version, 'C' for libavcodec version and 'U' for libavutil version).Navigate to the folder that contains FFmpeg and select the file ' ffmpeg.55.64bit.dylib'.If the ' Locate FFmpeg' dialog appears, click Browse.If a ' Success' message indicates Audacity has now automatically detected valid FFmpeg libraries and asks if you want to detect them manually, click No, then OK to close Preferences.To do this, access Preferences then the ' Libraries' tab on the left:Īs in the image above, the 'FFmpeg Library Version' will say ' FFmpeg library not found'.

If you installed FFmpeg while Audacity was running, or if you installed FFmpeg to a non-default location, Audacity will ask you to configure Preferences to locate the FFmpeg library.
