This is a Kodi FLAC audio encoder add-on.
When building the addon you have to use the correct branch depending on which version of Kodi you're building against.
If you want to build the addon to be compatible with the latest kodi master commit, you need to checkout the branch with the current kodi codename.
Also make sure you follow this README from the branch in question.
git clone --branch master https://github.com/xbmc/xbmc.gitgit clone --branch Nexus https://github.com/audioencoder.flac/audioencoder.flac.gitcd audioencoder.flac && mkdir build && cd buildcmake -DADDONS_TO_BUILD=audioencoder.flac -DADDON_SRC_PREFIX=../.. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../../xbmc/addons -DPACKAGE_ZIP=1 ../../xbmc/project/cmake/addonsmake
The add-on files will be placed in ../../xbmc/addons so if you build Kodi from source and run it directly
the add-on will be available as a system add-on.
