+    cd ..
+
+    # x264
+    curl -LO https://download.videolan.org/pub/videolan/x264/snapshots/last_stable_x264.tar.bz2
+    mkdir x264-snapshot-stable
+    tar -xf last_stable_x264.tar.bz2 --directory x264-snapshot-stable --strip-components=1
+    cd x264-snapshot-stable

+    make -j$(nproc)
+    sudo make install
+    cd ..
+
+    # make deps available
+    export CFLAGS="${CFLAGS:-} -I/usr/local/include"
+    export LDFLAGS="${LDFLAGS:-} -L/usr/local/lib"
+    echo 'export CFLAGS="${CFLAGS:-} -I/usr/local/include"' >> "${HOME}/.bashrc"
+    echo 'export LDFLAGS="${LDFLAGS:-} -L/usr/local/lib"' >> "${HOME}/.bashrc"
+    if ! grep '\/usr\/local\/lib' /etc/ld.so.conf; then
+        echo '/usr/local/lib' | sudo tee --append /etc/ld.so.conf
+        sudo ldconfig
