This is due to incompatability with ffmpeg and x264. What you can do is try another version of x264. You will be able to download older version of x264 from ftp://ftp.videolan.org/pub/x264/snapshots On 2018-08-14, it failed with latest stable snapshot. So i tried 14 days old stable snapshot

cd /usr/local/src/
wget ftp://ftp.videolan.org/pub/x264/snapshots/x264-snapshot-20180730-2245-stable.tar.bz2
tar xvf x264-snapshot-20180730-2245-stable.tar.bz2
cd /usr/local/src/x264-snapshot-20180730-2245-stable
make clean && make distclean
./configure --prefix=/usr --enable-shared
make && make install
ldconfig
