Hello I made an electron app that uses ffmpeg to combine audio and renders video, it works fine on windows, linux, and modern mac osx computers, but a user has reported to me that on an older version of mac osx such as High Sierra 10.13, the way that I have setup ffmpeg does not work.
I have a virtual machine with High Sierra v10.13 where I install RenderTune-mac.dmg from my RenderTune releases page, then I download 2 audio files and the image from this link. I open RenderTune, and try render a video. My command to combine the audio files into a single mp3 works fine, but when I try to combine that mp3 with the image file, the ffmpeg build I have packaged with my electron app fails with this error:
Command was killed with SIGABRT (Aborted): /Applications/RenderTune.app/Contents/Resources/ffmpeg -loop 1 -framerate 2 -i /Users/martin/Downloads/R-3777978-1344032418-8379.jpeg.jpg -i /Users/martin/Downloads/output-871140.mp3 -y -acodec copy -b:a 320k -vcodec libx264 -b:v 8000k -maxrate 8000k -minrate 8000k -bufsize 3M -filter:v scale=w=1920:h=1954 -preset medium -tune stillimage -crf 18 -pix_fmt yuv420p -shortest /Users/martin/Downloads/concatVideo-871140.mp4

These files will render fine on windows/linux and recent mac versions. In order to package ffmpeg in my electron app on mac computers I had to build a custom sandboxed version with no dynamically linked libraries. I have a .sh file that automatically downloads ffmpeg and builds it with all the necessary flags for mac computers. https://github.com/MartinBarker/RenderTune/blob/master/buildffmpeg.sh Inside this .sh file is where I compile ffmpeg using these flags :
./configure \
--pkgconfigdir="$WORKSPACE/lib/pkgconfig" \
--prefix=${WORKSPACE} \
--pkg-config-flags="--static" \
--extra-cflags="-I$WORKSPACE/include -mmacosx-version-min=${MACOS_MIN}" \
--extra-ldflags="-L$WORKSPACE/lib -mmacosx-version-min=${MACOS_MIN}" \
--extra-libs="-lpthread -lm" \
--enable-static \
--disable-securetransport \
--disable-debug \
--disable-shared \
--disable-ffplay \
--disable-lzma \
--disable-doc \
--enable-version3 \
--enable-pthreads \
--enable-runtime-cpudetect \
--enable-avfilter \
--enable-filters \
--disable-libxcb \
--enable-gpl \
--enable-nonfree \
--disable-libass \
--enable-libfdk-aac \
--enable-libmp3lame \
--enable-libx264
If I try to run this script in my High Sierra VM, it fails with this message:
Unknown option "-extra-libs=-lpthread"
if I remove that flag it fails with a different message:
Unknown option "--enable-static"
I need this flag in order to release my electron app on the mac apple store, can anyone help me compile a static version of ffmpeg that works on old versions like High Sierra 10.13 as well as works on modern mac os systems?
You'll need multiple versions if you are supporting multiple OSes and their various versions. I successfully compiled FFmpeg on High Sierra 10.13 by compiling AdoptOpenJDK and then compiling FFmpeg 2.8. I used homebrew manually and will now automate it to use network requests to download static versions.
