• electron ffmpeg mas build "Illegal instruction : 4"

  8 mars 2021, par Martin

  I am trying to release an electron app on the Mac Apple Store (mas), my electron app uses ffmpeg to render videos. In order to release my app on the mac apple store, It needs to be sandboxed, and by default ffmpeg makes calls to external libraries so I need to statically build ffmpeg and package it with my app. My code is on the 'mas-ffmpeg-fix' branch : https://github.com/MartinBarker/digify/tree/mas-ffmpeg-fix

  


  My static ffmpeg build works before I build my app, but after running electron-builder build --mac, the ffmpeg executable now fails with Illegal instruction: 4

  


  This is the full timeline of building/packaging/submitting my app to the mac apple store and where the error first appears :

  


  


  • In Digify repo :

    


  


  • clone, configure, and build static ffpmeg : “sudo rm -rf ffmpeg-mac/ && npm run download-ffmpeg”

    


  


  • download-ffmpeg command is inside package.json and runs this :
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg-mac && cd ffmpeg-mac && ./configure pkg_config='pkg-config --static' --pkg-config-flags='--static' --libdir=/usr/local/lib --extra-version=ntd_20150128 --disable-shared --disable-lzma --enable-gpl --enable-pthreads --enable-nonfree --enable-libass --enable-libfdk-aac  --enable-libmp3lame  --enable-libx264 --enable-static --enable-filters --enable-runtime-cpudetect && make && cd ..

    


  


  • Check if any dylibb files in the static ffmpeg build with command : “otool -L ffmpeg-mac/ffmpeg | grep /usr/local”

    


  


  • If there are any, move them to folder in desktop, run ‘otool’ again to ensure there are no dynamic libraries, rebuild static ffmpeg.

    


  


  • there will now be a folder 'ffmpeg-mac' which contains static versions of ffmpeg and ffprobe

    


  


  


  Using ffmpeg with electron UI : works
Using Ffmpeg with command-line command :
/Users/martinbarker/Documents/projects/digify-new/ffmpeg-mac/ffmpeg -h
Works

  


  

  • Build mac mass app with “npm run build-mas“

  


  • When this command finishes it will output two files inside the /dist/mas/ folder : Digify.app and Digify-01.20.pkg (or whatever version number it is)
Ffmpeg command-line check :
/Users/martinbarker/Documents/projects/digify-new/dist/mas/Digify.app/Contents/Resources/ffmpeg -h
Illegal instruction : 4

  


  


  This is the first place the error appears, after building my mac mac-apple-store app, ffmpeg fails with this err.

  


  

  • Sign built app with .sh file : “sh mas-sign-script.sh”
view .sh file here

    

    • the .sh file will output Digify-mac.pkg

    


    


  


  • Easier command to both build & sign : “sudo rm -rf dist/mas/ && npm run build-mas && sh mas-sign-script.sh”

  


  • Upload the outputted “Digify-mac.pkg” file & submit to apple for review

  


  


  Once this app gets published in the store, if you download it and try to run an ffmpeg command with the electron UI, it fails with this error :

• FFMPEG "Could not allocate memory" Errors through php

  10 décembre 2019, par Applepiee

  I’ve tried to find a solution online for days now but cannot find any solution.

  I just switched server (Intel Xeon to AMD) and since the switch I’ve not been able to get ffmpeg conversions working through the php script. ffmpeg was the exact same version and all php settings are set.

  All commands that the script executes (copied from log files) were tried in shell and executed with no problems.

  The errors look like this :
