• avutil/mips : refactor msa load and store macros.

  17 juillet 2019, par Shiyou Yin

  avutil/mips : refactor msa load and store macros.
  Replace STnxm_UB and LDnxm_SH with new macros ST_H/W/D1/2/4/8.
  
  The old macros are difficult to use because they don't follow the same parameter passing rules.
  
  Changing details as following :
  
  1. remove LD4x4_SH.
  
  2. replace ST2x4_UB with ST_H4.
  
  3. replace ST4x2_UB with ST_W2.
  
  4. replace ST4x4_UB with ST_W4.
  
  5. replace ST4x8_UB with ST_W8.
  
  6. replace ST6x4_UB with ST_W2 and ST_H2.
  
  7. replace ST8x1_UB with ST_D1.
  
  8. replace ST8x2_UB with ST_D2.
  
  9. replace ST8x4_UB with ST_D4.
  
  10. replace ST8x8_UB with ST_D8.
  
  11. replace ST12x4_UB with ST_D4 and ST_W4.
  Examples of new macro : ST_H4(in, idx0, idx1, idx2, idx3, pdst, stride)
  
  ST_H4 store four half-word elements in vector 'in' to pdst with stride.
  
  About the macro name :
  
  1) 'ST' means store operation.
  
  2) 'H/W/D' means type of vector element is 'half-word/word/double-word'.
  
  3) Number '1/2/4/8' means how many elements will be stored.
  
  About the macro parameter :
  
  1) 'in0, in1...' 128-bits vector.
  
  2) 'idx0, idx1...' elements index.
  
  3) 'pdst' destination pointer to store to
  
  4) 'stride' stride of each store operation.

• 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 :

  


  Uncaught (in promise) Error: Command was killed with SIGABRT (Aborted): /Users/martinbarker/Documents/projects/digify-new/dist/mas/Digify.app/Contents/Resources/ffmpeg -i /Users/martinbarker/Downloads/Steve Leach With The Crystal Grass Orchestra – Ocean Potion/9.

  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.
