• FFMPEG. Concatenate videos with a intro and music

  12 juillet 2019, par Micky

  I’m trying to merge videos with an intro and a background music.

  The intro.flv is a short file with video and audio.
  The other videos are without audio.
  ambientmusic.mp3 is audio to add to subsequent videos.
  A short fade for each file.

  ffmpeg -i intro.flv -i 0.mp4 -i 1.mp4 -i 2.mp4 -i ambientmusic.mp3 -filter_complex "[0] fade = in: 0: 25 [v0]; [1] fade = in: 0:25 [v1]; [2] fade = in: 0: 25 [v2]; [3] fade = in: 0: 25 [v3]; [v0] [v1] [v2] [v3] concat = 4 [v] "-map" [v] "-map a ./output/final.mp4

  Unfortunately the code only loads the first audio. Same result as

  -map 0: a

  If I use this instead it loads ambientmusic.mp3 on the whole video.

  -map 4: a

  But I’d like the audio of the Intro followed by the ambientmusic.mp3

  -map 0: a -map 4: a

• Discord,py ffmpeg and youtube_dl music bot isnt playing playlists

  5 décembre 2020, par CubacraftLP

  Hello Stackoverflow Community,
I got the following problem :

  


  Im using this code for playing music with my discord.py bot :

  


  @bot.command()
async def activate(ctx, url):
    
    YDL_OPTIONS = {'format': 'bestaudio', 'noplaylist':'True'}
    FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    voice = get(bot.voice_clients, guild=ctx.guild)

    if not voice.is_playing():
        with YoutubeDL(YDL_OPTIONS) as ydl:
            info = ydl.extract_info(url, download=False)
        URL = info['formats'][0]['url']
        voice.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
        voice.is_playing()

        else:
            await ctx.send("Already playing song")
            return


  


  but if im now pasting a playlist link, im geting the following error :

  


  Ignoring exception in command activate:
Traceback (most recent call last):
  File "C:\Users\\PycharmProjects\MusicBot\venv\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:/Users//PycharmProjects/MusicBot/main.py", line 47, in activate
    URL = info['formats'][0]['url']
KeyError: 'formats'

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

Traceback (most recent call last):
  File "C:\Users\\PycharmProjects\MusicBot\venv\lib\site-packages\discord\ext\commands\bot.py", line 903, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\\PycharmProjects\MusicBot\venv\lib\site-packages\discord\ext\commands\core.py", line 859, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\\PycharmProjects\MusicBot\venv\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: KeyError: 'formats'



  


  is there a way to fix it and make my bot play playlists ?
Thank you for your answers.

  


• Convert audio download with youtube-dl to flac ?

  16 mars 2017, par Urasam

  is it possible to download a youtube video as e.g. mp3 and then convert it to flac with ffmpeg ? I can specify the arguments that ffmpeg shall use after the download with —postprocessor-args but I don’t know how to get the file name there.

  —postprocessor-args "-i downloadedfile.xxx -c:a flac downloadedfile.flac"

  This would be the argument i want to use. Is this possible ?
