• ffmpeg installation on linux server

  7 juin 2015, par Aisha

  I was facing issues in converting files using ffmpeg there were errors coming like Unknown encoder ’lipvpx’ ’libopus’etc. I put the issue on stackoverflow people suggested me installing latest version of ffmpeg and rebuilding the libraries. i have 0.10.0 version of ffmpeg. I tried to reinstall from this link

  https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

  but i am getting different errors during installation like

  :git clone git://github.com/project.git
  
   github.com[0: 207.97.227.239]: errno=Connection refused
  
   fatal: unable to connect a socket (Connection refused)

  i tried using https, it gets installed but when i tried to install ffmpeg and enable libraries but its showing an error like libfdk_aac not found, libopus not found, libmp3lame not found although i installed all of them first but still i am lost.

  I have wasted my two days on this issue. Please help

  Thanks

• Ffmpeg commands in c# with variables

  12 juin 2017, par Fearhunter

  I am using the following command to slice a live stream in pieces :

  ffmpeg -i InputStreamURL -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls -hls_time 20 /var/www/html/ts/1.m3u8

  This is working fine when I execute this in command prompt. Now I want to use this command in C# with variables like this :

  private int cuttime;
  
  private int wrap;
  
  
  
  
  
  ffmpeg -i InputStreamURL -acodec aac -strict -2 -vcodec libx264 -hls_wrap wrap -f hls -hls_time cuttime /var/www/html/ts/1.m3u8

  I want to connect these variables with database and with a frontend interface in HTML5.

  How can I use c# variables into a ffmpeg command ?

  Kind regards

• discord.py FFMPEG Option reconnect not found

  19 avril 2021, par Lukelele

  I'm working on a music bot using discord.py, I've looked online and found that I needed to pass in ffmpeg options into discord.FFmpegPCMAudio() for the bot to not stop half way through the song. However it returns an error "Option reconnect not found."

  


  vc = await ctx.message.author.voice.channel.connect()

ydl_opts = {
    'format': 'bestaudio/best',
    'outtmpl': 'C:/Luke/YoutubeDLAudio/audio.mp3',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192'
    }],
    'prefer_ffmpeg': True,
    'keepvideo': True
}

ffmpeg_opts = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5','options': '-vn'}   # <---------------

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([url])

vc.play(discord.FFmpegPCMAudio(executable="C:/Luke/ffmpeg/bin/ffmpeg.exe", source="C:/Luke/YoutubeDLAudio/audio.mp3", **ffmpeg_opts))    <--------------


  


  Does anyone know the problem ? Thanks for any help.
