• Why is ffmpeg not working in my Python discord bot ?

  27 juillet 2023, par Dantheman1765

  I decided to start learning how to make a discord bot in Python and I have run into an issue with ffmpeg playing audio through my bot. I first wrote the code on my laptop and it worked fine but when I transferred it to my computer I ran into a problem and ffmpeg does not work. I can get the bot to join but it wont play anything. I am fairly certain I have installed all of the dependencies but I could be mistaken.

  


  Here is the code for the play function I am having trouble with :

  


  @client.command(pass_context=True) 
async def play(ctx, arg): 
    voice = ctx.guild.voice_client 
    source = FFmpegPCMAudio(arg) 
    player = voice.play(source) 


  


  and here are all of my imports :

  


  import discord 
from discord.ext import commands 
from discord import FFmpegPCMAudio 
from discord import Member


  


  I have installed ffmpeg and put it in my path as well.

  


  Whenever I try to use the play function, I get this message :

  


  discord.player ffmpeg process 33068 successfully terminated with return code of 4294967294.


  


  The process number changes but the return code stays the same.

  


  Can anyone help me get to the bottom of this or point me in the right direction ?

  


• Play video overlay over video not working in ffmpeg

  24 décembre 2017, par Sumit Marwha

  I am trying to play video over another video using ffmpeg. When i am trying to play video from starting then overlay video plays. But if i try to overlay video from n seconds it doesn’t work

  ffmpeg -i input.mp4 -i overlay.mp4
  
  -filter_complex [1:v]scale=920:920[out],[out][0]overlay=0:0:enable='between(t\,4\,8)'[out]
  
  -map [out] output.mp4

  If i change between(t\,4\,8) to between(t\,0\,4) then overlay video works normally. It is not working for between(t\,4\,8). Please help how to solve it

• ffmpeg converting RTSP to HLS stops working after hours

  28 juin 2019, par lin wang

  I’m using ffmpeg to convert RTSP stream to HLS, here is the command :

  ffmpeg -rtsp_transport tcp -i rtsp ://address/9012120.smil -vcodec copy -acodec copy -fflags +genpts -f hls -hls_wrap 5 -hls_list_size 2 -hls_time 3 /dev/shm/live/1/v.m3u8

  It worked properly at the beginning, but after hours(sometimes 8 hours sometimes less),it just stopped updating .ts files but the ffmpeg process was still running, so the hls stream just stuck.
  Check the log, no error log at the moment of the converting stopping,but before that there were some warning logs as below :

  [hls @ 0x57602c0] Non-monotonous DTS in output stream 0:1 ; previous : 5957536600,
  current : 2744367719 ; changing to 5957536601. This may result in incorrect timestamps in the output file.

  Any idea how to fix this ?
