FFmpeg: Unrecognized option preset
Solution 1:
For me this meant I had run configure with --disable-everything and enabled libx264, but not enabled its "encoder" so this fixed it up: --enable-libx264 --enable-encoder=libx264
Something like this:
ffmpeg $ ./configure --disable-everything --enable-libx264 --enable-encoder=libx264
You might be able to get away with just --enable-libx264
