• 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 :

• How to fix "Cannot find a valid font for the family Sans' while adding text on image using react-native-ffmpeg

  13 mai 2024, par coffee

  I am trying to add text on image using the code below
RNFFmpeg
.execute(`-y -i ${input} -vf "drawtext=text='Hello World':fontcolor=white:fontsize=75:x=0:y=0" ${output}`) ;

  


  I am not using any custom font but still get this error.

  


  Error :

  


  [Parsed_drawtext_0 @ 0x7f87a1ce40] Cannot find a valid font for the family Sans

  


  index.js:115 [AVFilterGraph @ 0x7f6765e760] Error initializing filter 'drawtext'

  index.js:115 Failed to inject frame into filter network : No such file or directory

  


  index.js:115 Error while processing the decoded data for stream #0:0

  


  Note :

  


  I also tried using a custom font but not able to do it.
When I use RNFFmpegConfig.setFontDirectory('../../assets/fonts') function and with it the following code to add text on image
RNFFmpeg
.execute(`-y -i ${input} -vf "drawtext=text='Hello World':fontfile='../../assets/fonts/MyFont.ttf':fontcolor=white:fontsize=75:x=0:y=0" ${output}`) ;

  


  It gives me the same error.

  


  How can I fix this issue.
