• I made this code, but the sound is too loud, how can I reduce it ?

  7 juillet 2021, par Luiz Torres

  I want to reduce the volume, but nothing I tried worked

  


  async def play1(guild : discord.Guild, url):
  guild = client.get_guild(guild)

• FFMPEG overlay issue for 2 videos, sound missing from second input

  27 juin 2021, par Abhishek Singh

  I'm trying to achieve an overlay with ffmpeg which take the two flv files as input and make a output and both videos playing simultaneously. things are working fine with below ffmpeg command :

  


  ffmpeg -i input1.flv -vf "[in] scale=359:320, pad=2*iw+6:ih [left]; movie=input2.flv, scale=359:320 [right]; [left][right] overlay=365:0 [out]" -b:v 3600k -y output.flv


  


  But issue is with the sound of second video and that is missing from the output.flv, only input1 sound is available in the output.flv.

  


  Console output is :

  I think -map is filter that is for the audio handling of both video. see this link.
