Answer by Dimitrios Desyllas for Failed building minitube with compiled libmpv v0.29.0

Have you tried to remove any libmpv package? Run:

sudo apt-get purge libmpv-dev libmpv && sudo apt-get autoremove

Afterwards install the required packages for sound:

sudo apt-get install libmp3lame-dev libx246-dev libfbdc-aac-dev

Afterwards recompile with these steps:

cd mpv-build
echo --enable-libmpv-shared > mpv_options
# Enable sound on minitube videos
echo --enable-libx264 >> ffmpeg_options
echo --enable-libmp3lame >> ffmpeg_options
echo --enable-libfdk-aac >> ffmpeg_options
./use-mpv-custom v0.29.0
./update
./rebuild -j4
sudo ./install

Also let the LD_LIBRARY_PATH to point into /usr/local/lib via:

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

And for more permanent results use either one of these commands:

• For your local user only:

echo "export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH" >> ~/.profile 

• For all users/global use:

echo "LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH" | sudo tee -a /etc/environment
