• My code accidently deleted my 'song.mp3' file in Discord.py music bot

  2 avril 2021, par Alkaria

  I was coding my discord bot and i was trying to make the bot not try to connect twice. Like, if it's already connected any user sends another ' !play' command, i don't want it to error. But that's not my problem. I or my code accidently deleted my 'song.mp3' file. How do i get it back. I closed the pycharm so i can't do 'CRTL + Z'.

  


  @client.command()

  


  async def play(ctx, url : str) :

  


  song_there = os.path.isfile("song.mp3")
try:
    if song_there:
        os.remove("song.mp3")
except PermissionError:
    await ctx.send("Şimdi Çalan şarkının bitmesini bekleyin. Yada '!stop' komutunu kullanın.")
    return
# connects the voice channel
connected = ctx.author.voice
audio = discord.FFmpegPCMAudio("song.mp3")

voiceChannel = discord.utils.get(ctx.guild.voice_channels, name='music')
if not discord.client.VoiceClient == None:  # None being the default value if the bot isnt in a channel (which is why the is_connected() is returning errors)
    await voiceChannel.connect()
    await ctx.send(f"Joined **{voiceChannel}**")
    discord.client.VoiceClient.play()
else:
    await ctx.send("I'm already connected!")



audio = discord.FFmpegPCMAudio("song.mp3")

# Dowloads the video from the link given

ydl_opts = {
    'format': 'bestaudio/best',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([url])
for file in os.listdir("./"):
    if file.endswith(".mp3"):
        os.rename(file, "song.mp3")


  


• ffmpeg overlay voice on a song with fade in and fade out

  22 octobre 2016, par Mehmed

  I have a fade in and fade out problem and used below code, but not completely resolve.
  I have a voice as voice.mp3 name with voice_length seconds length and a song that biggest from voice.
  I want mix with song from start_mix_time time.
  When voice start volume should be 0.2 and when voice end, volume return to 1.0.

  For example, if i have a voice by 10 s length and a song, song start playing and at position 3 s, starting to fade out to vol 0.2 and then, at 5 s, voice start over song and after 10 seconds, song fade in to vol 1 and play to end.

  Here is a sample :

  ffmpeg -i song1.mp3 -i voice2.mp3  -filter_complex "[0]asplit[a][b]; \
  
          [a]atrim=duration=voice_length,volume='1-max(0.25*(t-start_mix_time-2),0)':eval=frame[pre]; \
  
          [b]atrim=start=start_mix_time,asetpts=PTS-STARTPTS[song]; [song][1]amix=inputs=2:duration=first:dropout_transition=2[post]; \
  
          [pre][post]concat=n=2:v=0:a=1[mixed]" \
  
          -map "[mixed]" output.mp3

• ffmpeg stucks after each song

  11 juin 2017, par Halfbax

  When I start to stream to youtube, it works fine. Until the first song is over. After it the stream is in a loop of the last 20 seconds. I dont know why. The next song wont ever streamed.

  The audio stream is lag-free. <- tested

  case $1 in
  
                  start)
  
                          # VLC audio stream
  
                          su vlc -c "screen -dmS $VLC_PID_NAME cvlc --random /home/music/chill/*.mp3 --sout '#transcode{vcodec=none,acodec=mp3,ab=128}:standard{access=http,mux=raw,dst=localhost:8080/live.ogg}'"
  
  
  
                          sleep 2
  
                          # FFMPEG
  
                          # Static image + vlc audio stream
  
                          screen -dmS $FFMPEG_PID_NAME ffmpeg -loop 1 -framerate 2 -i '/home/forest.jpg' -i 'http://localhost:8080/live.ogg' -s "$INRES" -r "$FPS" -f alsa -ac 2 -vcodec libx264 -s "$OUTRES" -g 2 -acodec libmp3lame -b:a 128k -b:v 200k -ar 44100 -threads 0 -preset:v "$QUAL" -f flv "rtmp://a.rtmp.youtube.com/live2/$STREAM_KEY"
