• FFMPEG Streaming USB Webcam Video with Music Playlist

  3 février 2020, par 556duckvader

  Hello I am setting up streaming box that will be using a USB webcam as my video source and I am wanting to add in background audio to the live streams. I am wanting to do this by specifying a playlist and have it play through the audio files and then loop back once the playlist is finished. I have the ffmpeg command that allows me to stream the USB webcam and I can get one audio file to play but I can’t get seem to figure out how to get the playlist to work. Any help would be great. Below is what I have that is working.

  ffmpeg -f v4l2 -s 1280x720 -i /dev/video0 -i /home/pi/twitchMusic/ES_Arrows-MarVei.mp3 -c:a copy -c:v libx264 -r 24 -rtbufsize 1500k  -preset ultrafast -crf 23 -force_key_frames 'expr:gte(t,n_forced*2)' -minrate 2200k -maxrate 2200k -pix_fmt yuv420p -b:v 2500k -bufsize 2200k -f flv rtmp://live.twitch.tv/app/TWITCH_KEY

• Music bot returning errors at core.py and bot.py

  13 septembre 2021, par Loganox

  The code for the music bot I'm trying to write in python keeps returning an error with the following code :

  


  @bot.command(name='play_song', help='To play song')
async def play(ctx,url):
    
    #if not ctx.message.author.name=="Rohan Krishna" :
    #     await ctx.send('NOT AUTHORISED!')
    #     return
    if 1==1:#try :
        server = ctx.message.guild
        voice_channel = server.voice_client
        print("try 1 was a success")
        
        async with ctx.typing():
            filename = await YTDLSource.from_url(url, loop=bot.loop)
            #voice_channel.play(discord.FFmpegPCMAudio(executable="ffmpeg.exe", source=filename)) #ISSUE HERE
            print("try 2 was a success")
            voice = get(ctx.bot.voice_clients, guild=ctx.guild)
    
            #voice.play(discord.FFmpegPCMAudio('test.mp3'), after=your_check)
            #voice.source = discord.PCMVolumeTransformer(voice.source)
            #voice.source.volume = 0.5
        await ctx.send('**Now playing:** {}'.format(filename))
    if 1==0:#except:
        await ctx.send("The bot is not connected to a voice channel.")
        print("try 3 was unfortunately a success")


  


  It normally has a try/except function but I replaced it with if true and false statements to force it to run instead of breaking to determine the exact line of it breaking. The issue supposedly lies in

  


  voice_channel.play(discord.FFmpegPCMAudio(executable="ffmpeg.exe", source=filename)) #ISSUE HERE


  


  The error I get returned is :

  


  Traceback (most recent call last):
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "app2.py", line 75, in play
    voice.play(discord.FFmpegPCMAudio('test.mp3'), after=your_check)
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\player.py", line 225, in __init__

    raise ClientException(executable + ' was not found.') from None
discord.errors.ClientException: ffmpeg was not found.

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\ext\commands\bot.py", line 939, in invoke
    await ctx.command.invoke(ctx)

    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: ClientException: ffmpeg was not found.


  


  I added the print statements to determine which lines were working so those can obviously be ignored. It seems to be working fine except for this, other commands in the bot are working appropriately.
