• "Error : FFMPEG not found" : Error with simple Discord Bot

  23 décembre 2019, par Robin Seerig

  I’m using Windows (64-bit) with Node.js and npm installed.
  In my project file, I have run the following commands :

  npm init
  
  npm install discord.js --save
  
  npm install ffmpeg --save

  Now i just created the code for a basic bot here is the main code.
  I list here the important :

   if (message.content === '!play' && message.member.roles.has(message.guild.roles.find("name", config.role_name).id)) {
  
      if (!message.member.voiceChannel) return log("?");
  
         message.member.voiceChannel.join().then(function (connection){      
  
         });
  
   }

  Then, in Discord, I say the following :

   [1517932146]  Musik bot loaded
  
      (node:35760) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: FFMPEG not found

  I have already tested the following :

  • reinstallation of everything
  • others of the require names e.t.z.
  • simplify the code

  So if you have any ideas then let me know.

  Solution

  npm i ffmpeg-binaries@3.2.2-3

• How to fix the error "duplicate symbol _LOG_BUFFER_LENGTH"

  25 mai 2019, par Florentin Lupascu

  I have a Unity project embedded into Swift 4 and when I build the project I get an error from a plugin named FFmpeg (used to record the screen) and the error is next :

  duplicate symbol _LOG_BUFFER_LENGTH in:
  
      /Users/developers/Library/Developer/Xcode/DerivedData/DemoApp-bszfgmzljpyourbdjoxkdabtilki/Build/Intermediates.noindex/DemoApp.build/Debug-iphoneos/DemoApp.build/Objects-normal/arm64/cmdutils.o

  ld: 3 duplicate symbols for architecture arm64
  
  clang: error: linker command failed with exit code 1 (use -v to see invocation)

  I want to specify that if I export the project from Unity to Xcode without to embed it is working perfectly with this Plugin.
  What can be the problem with this error ?

  Until now I tried next thing to remove the error but none helped me :

  • I checked if I have "-ObjC" in Xcode in "Other Linker Flags" and I don’t have.
  • I removed a duplicate library (“libil2cpp.a”) from "Link Binary With Libraries" (XCODE)
  • I changed ’No Common Blocks’ from Yes to No (under Targets->Build Settings->Apple LLVM - Code Generation )

  At the end I have the same error.
  Here is a print screen :

  

  Thank you so much if you spend your time to read this and any idea will be helpful.
