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][1], then I
download 2 audio files and the image from [this link][2]. 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):

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][3]
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?**
