• Specifying FFMPEG in the requirements section of 'buildozer.spec' causing [libavformat/network.o] Error 1

  18 juillet 2022, par GJ78

  My question relates to how to mitigate an ffmpeg requirement listed in a buildozer.spec that is causing compile errors using buildozer.

  



  GOAL :

  



  Using buildozer to ensure FFMPEG can be embedded within a small Kivy app so i can utilise youtube_dl functionality on my android phone.

  



  THE ISSUE :
Specifying FFMPEG in the requirements section of 'buildozer.spec' causes the following error message :
  
common.mak:60 : recipe for target 'libavformat/network.o' failed
  
make : [libavformat/network.o] Error 1
  
make : Waiting for unfinished jobs...

  



  What have I done to resolve myself :
  
1. Ensured LOG LEVEL 2 is specified.

  



  


  2. Upgraded cython from Version 21 to 27. Then downgraded to 25, then 21 then 20 to see if this resolved anything. It didn't.

  


  3. In BUILDOZER.SPEC, switched between Android NDK crystax-ndk-10.3.2 and android-ndk-r16b. (Note have reverted back to Crystax 10.3.2) in my NDK PATH.

  


  4. In BUILDOZER.SPEC, changed android.api from 19 to 15 (just to see if this has any positive effects).

  


  5. executed : rm -Rf .buildozer between each compiling attempt.

  8. Lastly, when I remove ffmpeg from requirements in buildozer.spec, the .APK compiles successfully and i can deploy it on to my phone with the KIVY GUI. Obviously, ffmpeg functionality is not present.

  


  



  Current Environment Specs :

  



  

  1. Running Linux Mint 17.2 as a Virtual Box VM

  


  2. Buildozer Version : 0.35dev

  


  3. Cython Version : 0.25

  


  



  Any advice would be greatly appreciated.

  



  Lastly, if there is no obvious solution via buildozer, do i need to compile ffmpeg for Android separately and somehow include this somewhere in the buildozer spec file to prevent this error message ?

  



  Thanks in advance.
