• ffmpeg crashes in electron mac apple store build

  23 février 2021, par Martin

  UPDATE
I found the command otool -L ffmpeg-mac/ffmpeg | grep /usr/local which shows me which dynamicly linked files are in my ffmpeg build, it was point to 3 files so I moved them to my desktop and then built my mac apple store build, uploaded it to the app store, downloaded it, and tried to run it again but got a new less-descriptive error :

  The error says command failed with exit code 1 Operation not permitted, am I missing some entitlements for saving files on my computer in the final mac apple store build that gets uploaded to the app store ?

  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. I have successfully built my app, submitted it to the app store, had it approved, and downloaded/used it but my ffmpeg fails with this errir :

  I think this line is important ; file system sandbox blocked open() of '/usr/local/opt/libass/lib/libass.9.dylib' but I'm not sure what I should change with my static ffmpeg build so that it works in production and so that I can avoid the above error.

  


  My code is available on the branch mas-attempt-after-redesign here : https://github.com/MartinBarker/digify/tree/mas-attempt-after-redesign

  


  Inside my package.json I have the command download-ffmpeg which clones the ffmpeg repo, runs a configure command with some flags, and then builds ffmpeg into a folder called 'ffmpeg-mac', this folder gets packaged with the app for the mac apple store build.

  


  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 ..


  


  You can see in the above ffmpeg command the flag --enable-libass, but even though I have that flag included, after I build and sign my mac apple store build by running sudo rm -rf dist/mas/ && npm run build-mas && sh mas-sign-script.sh, the production build (once approved) fails with the above included error.

  11 avril 2023, par Anton Khirnov

  fftools/ffmpeg : store stream media type in OutputStream
  Reduces access to a deeply nested muxer property
  
  OutputStream.st->codecpar->codec_type for this fundamental and immutable
  
  stream property.
  Besides making the code shorter, this will allow making the AVStream
  
  (OutputStream.st) private to the muxer in the future.
