• ffmpeg not working from php

  12 février 2015, par ffmpeg fan

  spent 8 hours trying to make it work :
  i installed the version from http://ffmpeg.org/releases/ffmpeg-2.5.3.tar.bz2
  and also tried the yum version but it as not new enough for youtube-dl

  tried
  export PATH=$PATH :/usr/local/bin/ffmpeg and php apache still cant find ffmpeg

  apache user runs php script on centos 6.5
  calling my youtube-dl.php from php command line as root works (with ffmpeg) -
  calling my youtube-dl.php from php apache user works (not with ffmpeg) -

  what iam trying to do - shell exec youtube-dl (youtube dl calls ffmpeg in its binary code which there is now to modifiy it to add the full path)
  this works but the ffmpeg part
  my youtube-dl.php file

  $output = shell_exec('youtube-dl -o "/home/test/%(title)s.%(ext)s" '.$url.'      -f bestvideo+bestaudio 2>&1');
  
  echo "<pre>$output</pre>";
  
  
  
  
  
  # which ffmpeg
  
  /usr/local/bin/ffmpeg

  (someone on other pages on this site says local/bin is for customized versions but i downloaded it directly from ffmpeg and did the standard ./configure make make install )

  done :
  chmod 755 to /usr/local/bin/ffmpeg

  running ffmpeg as a test command directly (sometimes works and doesnt as i upgraded/rebooted/updatedb/etc)

  $output = shell_exec(’ffmpeg 2>&1’) ;
  echo "

  $output

  " ;
  result :
  

  sh : ffmpeg : command not found

• 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

  


• FFMPEG and AWS : What's the most efficient way to handle this ?

  28 mai 2022, par Red Vic

  I'm new to AWS and I originally built the FFmpeg functions on my Node.JS API. But I realized this is the wrong way to do it in a real-world app, and that you need to use separate Lambda functions in AWS that handle the video editing separately from the main server.

  


  I'm mainly a front-end developer but I'm open to learning new things.

  


  I basically have the following process in my app :

  


  

  • User uploads video.

  


  • I need to take that video and add a watermark to it.

  


  • I then need a copy of the watermarked video in a smaller resolution.

  


  • I then need a 6 seconds GIF of the smaller resolution video.

  


  • Finally, I need to upload the 3 edited files (2 .mp4's and 1 .gif) to S3, and remove the original, non-watermarked video.

  


  


  Here are my questions to be clear :

  


  

  • Should I upload the original file to S3 or to the server ? And why ?

  


  • Is the process above doable in a single Lambda function ? Or do I need more Lambda functions ?

  


  • How would you handle this problem, personally ?

  


  


  I originally built it by chaining one function to the next with promises, but AWS seems like a different world of doing things and the way I originally built it would not work.

  


  Thanks a lot.
