• 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 ?

  


• What makes the bitrate of dash stream output low as compared to bitrate of input mp4 video

  7 janvier 2021, par Chinmaey Shende

  I used ffmpeg to convert bbb.mp4 to dash stream. I used the ffprobe to get the bitrates of input and output (shown below)
For the same resolution video 1920x1080 input has bit rate 2998 kb/s where as output has bitate of 20 kb/s.
My profile is set to "-b:v:0 200K -s:v:0 640x360 -b:v:1 600K -s:v:1 852x480 -b:v:2 4000K -s:v:2 1920x1080".
I am trying to understand what determines the output bit rate for the dash stream ?
Why does my output different from the input profile set in ffmpeg command

  



  Input video stream - bbb.mp4

  



  '''  Duration: 00:10:34.53, start: 0.000000, bitrate: 3481 kb/s
    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 2998 kb/s, 30 fps, 30 tbr, 30k tbn, 60 tbc (default)'''


  



  Output :

  



  '''  Duration: 00:10:34.60, start: 630.000000, bitrate: 20 kb/s

'''


  



  I tried to look in ffprobe documentation I could not find the definition of the bit_rate field output in ffprobe.

  



  Can you please help me to understand this ?

  


• ffmpeg not returning anything on Dash

  10 janvier 2021, par whatcrisis

  I am trying to extract subtitles from an MPD, but ffmpeg is not returning anything. If I try first a simple command such as :

  


  ffmpeg -i Downloads\Manifest.mpd


  


  After just 2 seconds it stops. This is the log :

  So basically, it did nothing. I have libxml2 installed and I am confused since there is no error at all. Any help ? Thank you !
