• Mac app crash : Termination Reason : Namespace CODESIGNING, Code 0x2 [closed]

  29 janvier 2020, par dummyapps

  The app always works fine, but it suddenly crashes this evening and report "Namespace CODESIGNING, Code 0x2", I have no idea why, the code worked for several year, it seems that certain certificate invalid.

  This app use FFmpeg library to snapshot video, I did some test on it :

  1. I rebuild the source code, It still crash.

  2. It only crash on Mac OS 10.15, it works fine on 10.13

  3. I use atos to analyse the crash report, the output of atos indicate that FFmpeg library failed, but it should not. The code works for several year, I don’t think the code has bug.

  4. I submit a Technical Support to Apple developer, they also have no idea why.

• How to prevent App sandoxing from blocking a plugin usage after codesigning ?

  27 mai 2020, par Cyhzault

  I'm struggling to codesign my Unity application in order to push it to the Mac App Store. I followed the unity recommended process but some issues appeared after the codesign command. I've been able to fix some of them by adding new keys in my entitlement file but i'm still stuck due to the App Sandboxing mecanism.

  



  In my application I use an external plugin named FFmpeg to manage video encoding. After codesigning with the mandatory app sandboxing entitlement set to true, the plugin stopped working and i have no log explaining why.

  



  I tried multiple solutions detailed in other posts like defining an AppSandbox inheritance or adding more keys to my entiltement file but none of them worked.

  



  I'm new to codesigning and here is my process and entitlements file :

  



  

  1. chmod -R a+xr ./MY_APP.app

  


  2. codesign --force --sign '3rd Party Mac Developer Application: My Company (id)' --entitlements ./FFmpeg.entitlements ./MY_APP.app/Contents/Resources/Data/StreamingAssets/FFmpegOut/macOS/ffmpeg

  


  3. codesign -f --deep -s '3rd Party Mac Developer Application: My Company (id)' --entitlements ./MY_APP.entitlements ./MY_APP.app

  


  4. Verify codesign & Product build - both successful

  


  



  The main entitlement file for the app (MY_APP.entitlements) :

  



  &lt;?xml version="1.0" encoding="UTF-8"?>&#xA;&#xA;<plist version="1.0">&#xA;    <dict>&#xA;            <key>com.apple.security.app-sandbox</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.files.user-selected.read-write</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.network.client</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.files.user-selected.executable</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.cs.allow-unsigned-executable-memory</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.cs.disable-library-validation</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.cs.allow-dyld-environment-variables</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.get-task-allow</key>&#xA;            <true></true>&#xA;    </dict>&#xA;</plist>&#xA;

  



  Here is the second entitlement file (FFmpeg.entiltlement) for the plugin with inheritance :

  



  &lt;?xml version="1.0" encoding="UTF-8"?>&#xA;&#xA;<plist version="1.0">&#xA;    <dict>&#xA;            <key>com.apple.security.app-sandbox</key>&#xA;            <true></true>&#xA;            <key>com.apple.security.inherit</key>&#xA;            <true></true>&#xA;    </dict>&#xA;</plist>&#xA;

  



  The plugin i used can be found on github, i'll cross post my issue there as well.

  



  I will gladfully take any idea or solution, 
Thanks for your help,

  



  Regards,
Alexis

  


• How can we reduce the size of audio file after uploading ?

  8 novembre 2019, par Arjun Pujari

  I have used this command in the terminal to install the package : composer require pbmedia/laravel-ffmpeg. The package is successfully downloaded, but I don’t know how to use it. I don’t even know if this package can also reduce the audio file size or not.

  Anyone know any other library or package ?

      
  
          <form action="{{route('upload')}}" method="post" enctype="multipart/form-data">
  
              Select Audio to upload:
  
              <input type="file" />
  
              <input type="submit" value="upload MP3" />
  
          </form>
  
      
  
  
  
  
  
  &lt;?php

  Here is my controller. Write basic code for save file :

  namespace App\Http\Controllers;
  
  
  
  use Illuminate\Http\Request;
  
  use Pbmedia\LaravelFFMpeg\FFMpeg;
  
  
  
  class FileCompress extends Controller
  
  {   
  
      public function compressFile(Request $request)
  
      {
  
            $uploadFileName = mt_rand().time(). '.' . $file->getClientOriginalExtension();
  
            $filetype = substr($file->getClientMimeType(), 0, strpos($file->getClientMimeType(), "/"));
  
  
  
          if($filetype == 'video'){
  
  
  
            $localpath =  public_path().'/videos/'.$uploadFileName;
  
           //code for video file compress.
  
          }else{
  
            //code for audio file compress.
  
          }
  
      }
  
  }

  But I need to reduce the audio file size when a file is uploaded or reduce the file size immediately after the file upload. How can i do that ?
