• Revision 511d218c60 : SSSE3 convolution optimization Optimizing all SSSE3 assembly for convolution : 1

  21 novembre 2013, par levytamar82

  SSSE3 convolution optimization

  Optimizing all SSSE3 assembly for convolution :
  1. vp9_filter_block1d4_h8_sse2
  2. vp9_filter_block1d8_h8_sse2
  3. vp9_filter_block1d16_h8_sse2
  4. vp9_filter_block1d4_v8_sse2
  5. vp9_filter_block1d8_v8_sse2
  6. vp9_filter_block1d16_v8_sse2
  my optimization include :
   processing 2x8 elements in one 128 bit register instead of processing
  8 elements in one 128 bit register.
   removing unecessary loads.
  This optimization gives between 2.4% user level gain for 480p input
  and 1.6% user level gain for 720p.
  This Optimization done only for 64bit.

• How to use avcodec_register() in C++ program

  31 juillet 2017, par Michael Ivanov

  I don’t want to register all the codecs with avcodec_register_all() ;
  I want to register one specific codec.
  Strangly, I cannot find any working example that shows how to use avcodec_register() . Most of the examples I found suggest something like this :

  extern AVCodec ff_h264_decoder;
  
  
  
  avcodec_register(&ff_h264_decoder);

  But I am getting

  unresolved external symbol

  Error from the linker. I tried to wrap the struct with extern "C" , but still the same.Do I need to link h264 lib to access those structs ?

• AttributeError : 'FFmpegAudio' object has no attribute '_process' while trying to play audio from URL

  13 août 2022, par jmcamacho7

  I can't find any solution online and I don't know what's wrong.

  


  My code is : (Not pasting the URL getting since that works fine)

  


  from urllib import parse, request
import re
import pafy
from discord import FFmpegPCMAudio, PCMVolumeTransformer

FFMPEG_OPTIONS = {
    'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'
}

@bot.command(pass_context=True)
async def play(ctx, * , search):
  query_string = parse.urlencode({'search_query': search})
  html_content = request.urlopen('http://www.youtube.com/results?' + query_string)
  search_results=re.findall('watch\?v=(.{11})',html_content.read().decode('utf-8'))
  print(search_results[0])
  
  if(ctx.author.voice):
    channel = ctx.message.author.voice.channel
    await ctx.send("https://www.youtube.com/watch?v="+search_results[0])  
    url = "https://www.youtube.com/watch?v="+search_results[0]
    conn = await channel.connect()
    conn.play(discord.FFmpegAudio(url, **FFMPEG_OPTIONS))
  else:
    await ctx.send("Necesitas estar en un canal de audio para usar este comando")


  


  It just gives me this error everytime I try it :

  


  Traceback (most recent call last):
  File "/home/runner/HakuBot/venv/lib/python3.8/site-packages/discord/player.py", line 103, in __del__
    self.cleanup()
  File "/home/runner/HakuBot/venv/lib/python3.8/site-packages/discord/player.py", line 154, in cleanup
    proc = self._process
AttributeError: 'FFmpegAudio' object has no attribute '_process'


  


  Anyway to solve this ?
