It is a bug in ffmpeg version. It still is in 3.4.

[bnku]

Use the actual snapshot of ffmpeg from https://ffmpeg.org/releases/ffmpeg-snapshot-git.tar.bz2

[jedrekdomanski]

@bnku
I've taken a look at the bash script and I see that the script uses version 3.1, here's the code.

ffmpeg_version="3.1"
if [ ! -f  ffmpeg-${ffmpeg_version}.tar.bz2 ]; then
  wget -4 http://ffmpeg.org/releases/ffmpeg-${ffmpeg_version}.tar.bz
fi

So I changed the script to use ffmpeg-snapshot-git.tar.bz2 version - as you suggest - but it errors out during configurations at line 201 --enable-x11grab.

Unknown option "--enable-x11grab".
See ./configure --help for available options.

Correct me if I am wrong.

[bnku]

use the --enable-libxcb instead

After applying certain modifications to the script, it compiles everything fine. Here is the the modified parts of the script and a screen shot confirming it all works fine.

BuildFFmpeg() {
    echo "Compiling ffmpeg"
    cd $source_dir
    ffmpeg_version="snapshot-git"
    if [ ! -f  ffmpeg-${ffmpeg_version}.tar.bz2 ]; then
        wget -4 http://ffmpeg.org/releases/ffmpeg-${ffmpeg_version}.tar.bz2
    fi
    tar xjf ffmpeg-${ffmpeg_version}.tar.bz2
    cd ffmpeg
    PKG_CONFIG_PATH="${build_dir}/lib/pkgconfig" ./configure \
        --prefix="$build_dir" \
        --extra-cflags="-fPIC -m64 -I${inc_dir}" \
        --extra-ldflags="-L${build_dir}/lib" \
        --bindir="$bin_dir" \
        --enable-gpl \
        --enable-libass \
        --enable-libfdk-aac \
        --enable-libfreetype \
        --enable-libmp3lame \
        --enable-libopus \
        --enable-libtheora \
        --enable-libvorbis \
        --enable-libvpx \
        --enable-libx264 \
        --enable-nonfree \
        --enable-nvenc \
        --enable-pic \
        --enable-libxcb \
        --extra-ldexeflags=-pie \
        --enable-shared
    make -j${cpus}
    make install
}

I also removed my previous installation of OBS and now the new installation has NVENC.H264 encoder.
