• 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.

     android.ant_path =

  


  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.

  


• h264 : move the scratch buffers into the per-slice context

  h264 : move the scratch buffers into the per-slice context
  Also change the method for allocating them. Instead of two possible
  
  alloc calls from different places, just ensure they are allocated at the
  
  start of each slice. This should be simpler and less bug-prone than the
  
  previous method.

• avutil/pixdesc : deprecate AV_PIX_FMT_FLAG_PSEUDOPAL

  29 mars 2018, par wm4

  avutil/pixdesc : deprecate AV_PIX_FMT_FLAG_PSEUDOPAL
  PSEUDOPAL pixel formats are not paletted, but carried a palette with the
  
  intention of allowing code to treat unpaletted formats as paletted. The
  
  palette simply mapped the byte values to the resulting RGB values,
  
  making it some sort of LUT for RGB conversion.
  It was used for 1 byte formats only : RGB4_BYTE, BGR4_BYTE, RGB8, BGR8,
  
  GRAY8. The first 4 are awfully obscure, used only by some ancient bitmap
  
  formats. The last one, GRAY8, is more common, but its treatment is
  
  grossly incorrect. It considers full range GRAY8 only, so GRAY8 coming
  
  from typical Y video planes was not mapped to the correct RGB values.
  
  This cannot be fixed, because AVFrame.color_range can be freely changed
  
  at runtime, and there is nothing to ensure the pseudo palette is
  
  updated.
  Also, nothing actually used the PSEUDOPAL palette data, except xwdenc
  
  (trivially changed in the previous commit). All other code had to treat
  
  it as a special case, just to ignore or to propagate palette data.
  In conclusion, this was just a very strange old mechnaism that has no
  
  real justification to exist anymore (although it may have been nice and
  
  useful in the past). Now it's an artifact that makes the API harder to
  
  use : API users who allocate their own pixel data have to be aware that
  
  they need to allocate the palette, or FFmpeg will crash on them in
  
  _some_ situations. On top of this, there was no API to allocate the
  
  pseuo palette outside of av_frame_get_buffer().
  This patch not only deprecates AV_PIX_FMT_FLAG_PSEUDOPAL, but also makes
  
  the pseudo palette optional. Nothing accesses it anymore, though if it's
  
  set, it's propagated. It's still allocated and initialized for
  
  compatibility with API users that rely on this feature. But new API
  
  users do not need to allocate it. This was an explicit goal of this
  
  patch.
  Most changes replace AV_PIX_FMT_FLAG_PSEUDOPAL with FF_PSEUDOPAL. I
  
  first tried #ifdefing all code, but it was a mess. The FF_PSEUDOPAL
  
  macro reduces the mess, and still allows defining FF_API_PSEUDOPAL to 0.
  Passes FATE with FF_API_PSEUDOPAL enabled and disabled. In addition,
  
  FATE passes with FF_API_PSEUDOPAL set to 1, but with allocation
  
  functions manually changed to not allocating a palette.
