• Parse and drop gain control data, so that SSR packets decode.

  16 février 2018, par Dale Curtis

  Parse and drop gain control data, so that SSR packets decode.
  This will result in poor quality audio for SSR streams, but they
  
  will at least demux and decode without error ; partially fixing
  
  ticket #1693.
  This pulls in the decode_gain_control() function from the
  
  ffmpeg summer-of-code repo (original author Maxim Gavrilov) at
  
  svn ://svn.mplayerhq.hu/soc/aac/aac.c with some minor modifications
  
  and adds AOT_AAC_SSR to decode_audio_specific_config_gb().

• ffmpeg : "Error setting profile"

  26 février 2017, par P. Reid

  I’ve been having trouble using ffmpeg to compress videos to something readable by quicktime. My goal in the end is to have a simple command that I can use to compress high bitrate videos (ie screencaptures) to something more reasonable to be able to share them with people.

  I want to use a command I found here as a starting point :

  ffmpeg -i input-file.avi -codec:v libx264 -profile: high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -codec:a libfdk_aac -b:a 128k output_file.mp4

  Unfortunately I get this error :

  [libx264 @ 0x7f92ab81c200] Error setting profile high.
  
  [libx264 @ 0x7f92ab81c200] Possible profiles: baseline main high high10 high422 high444
  
  Stream mapping:
  
    Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))
  
  Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  If I take out the -profile: high the command functions but the output still doesn’t open in quicktime (it does in VLC). I can’t find the keyword -profile on the ffmpeg man page : https://ffmpeg.org/ffmpeg.html so I don’t know if this is important or what to do about it.

  Does anyone know what might be causing my problem ? What should I do to try and debug this problem ? I would describe myself as inexperienced so sorry if I’m missing something obvious.

  Thanks in advance for your help,
  Peter

  This is my ffmpeg version :

• How do I loop audio files in discord.py ?

  I cannot for the life of me find or figure out a solution that works anymore. here is both the bit of code that is actually important, and the whole file if you would like to see that too

  is the code poorly made and/or badly organized ? probably. but this is a personal project and did not expect to be sharing this with anyone. If you need clarification on anything lmk.

  


  with the code here, the issue im getting is when I do the looped version, the bot disconnects for a frame and reconnects, then I get this error

  


  


  discord.ext.commands.errors.CommandInvokeError : Command raised an exception : ClientException : Not connected to voice.

  


  


  the bot does not disconnect immediately when not using the looped version, and trying to manually reconnect it at the start of the loop gives me an error saying it's already connected.

  


  also sidenote I did not write the YTDLSource class or the ytdl_format_options.
