  avfilter/vf_gblur : add x86 SIMD optimizations
  The horizontal pass get 2x performance with the patch
  
  under single thread.
  Tested overall performance using the command(avx2 enabled) :
  
  ./ffmpeg -i 1080p.mp4 -vf gblur -f null /dev/null
  
  ./ffmpeg -i 1080p.mp4 -vf gblur=threads=1 -f null /dev/null
  
  For single thread, the fps improves from 43 to 60, about 40%.
  
  For multi-thread, the fps improves from 110 to 130, about 20%.

• How can i capture microphone stream and change with ffmpeg ?

  23 janvier 2020, par Emre Erol

  I am using ffmpeg for chancing wav file with below code on python ;

  song = subprocess.Popen(["ffmpeg", "-i", sys.argv[1], "-af", "asetrate=22050,aresample=44100,atempo=2", "-f", "wav", "pipe:1"],stdout=subprocess.PIPE)

  But i want to send microphone stream to this subprocess. How can i change sys.argv[1] to microphone stream data ?

  I am using pyaudoio library for capturing sound in python.

        voice_clients[ctx.guild.id].play(player, after=lambda e: asyncio.run_coroutine_threadsafe(play_next(ctx), bot.loop))


  


  ffmpeg installed and added in PATH
ffmpeg lib for python added

  


  I tried other variations of ffmpeg(like FFmpegPCMAudio) but this didn't solve the problem. I also tried to just copy-paste(Someone else's code that performs the same functions), which also did not give anything. I think the problem is not in the code.

  


  Traceback :
