• x86inc : AVX-512 support

  x86inc : AVX-512 support
  AVX-512 consists of a plethora of different extensions, but in order to keep
  
  things a bit more manageable we group together the following extensions
  
  under a single baseline cpu flag which should cover SKL-X and future CPUs :
  
   * AVX-512 Foundation (F)
  
   * AVX-512 Conflict Detection Instructions (CD)
  
   * AVX-512 Byte and Word Instructions (BW)
  
   * AVX-512 Doubleword and Quadword Instructions (DQ)
  
   * AVX-512 Vector Length Extensions (VL)
  On x86-64 AVX-512 provides 16 additional vector registers, prefer using
  
  those over existing ones since it allows us to avoid using `vzeroupper`
  
  unless more than 16 vector registers are required. They also happen to
  
  be volatile on Windows which means that we don't need to save and restore
  
  existing xmm register contents unless more than 22 vector registers are
  
  required.
  Big thanks to Intel for their support.

  avcodec/mips : Improve hevc uni weighted vert mc msa functions
  Pack the data to half word before clipping.
  
  Use immediate unsigned saturation for clip to max saving one vector register.

• I couldn't embed ffmpeg package while trying to create an exe file for my python script

  1er juillet 2024, par Abdelrahman Zaki

  I'm trying to create a python script that deals with audios and videos.
so, I need to use ffmpeg and it works -for details, I used a CLI program that deals with it, not me-, but when I tried to create an exe file using pyinstaller, it doesn't contain ffmpeg packages within it !
Now, if anyone want to use the app, he couldn't until he downloads ffmpeg independently, and it's a further step that makes it harder reach my app.
What is the solution/the way to embed ffmpeg with my app ?

  


  

  • What I'm expecting is to find a solution...

  


  • What I've tried is that :

  


  • I tried to search on google, but I found nothing.

  


  • I tried to ask chatGPT and it gives me a script that doesn't work :)

  



  


  # my_app.spec
# Run with: pyinstaller my_app.spec

# Basic PyInstaller configuration
block_cipher = None

a = Analysis(['main.py'],  # Replace 'main.py' with your Python script
             pathex=['.'],
             binaries=[('C:\\ffmpeg\\bin\\ffmpeg.exe', '.'), 
                       ('C:\\ffmpeg\\bin\\ffplay.exe', '.'),
                       ('C:\\ffmpeg\\bin\\ffprobe.exe', '.')],
             ...

             # Rest of the Analysis configuration goes here

             pyz = PYZ(a.pure, a.zipped_data,
                      cipher=block_cipher)

             exe = EXE(pyz,
                       a.scripts,
                       a.binaries,
                       a.zipfiles,
                       ...

                       # Rest of the EXE configuration goes here
