• Extracting audio from a video from ".m3u8" URL

  12 février 2021, par leo

  I am trying to extract audio from a video from ".m3u8" URL. It works with this command which is stated below but I could not find how can I do that with a C# wrapper library, like Xabe.FFmpeg, FFMPEGCore. Does anybody know how to do that ?

  


  PS : I am using .net core

  


  ffmpeg -i "https://blablabla/playlist.m3u8" -acodec mp3 -ab 128k test.mp3

  


• FFmpeg python doesn't merge

  24 avril 2021, par MaLoLHDX

  I was making this youtube downloader GUI with Python : it asks for the URL, gives you a list with the possible quality settings and downloads the selected video file and the best audio file with youtube-dl. However, when I tell ffmpeg to merge the two separate downloaded files, it doesn't do anything and it doesn't say anything in the console either. Is there anything I'm missing ?

  


  Here's the relevant part of the code (starts at line 153) :

  


              #Adding input arguments for ffmpeg
            ffmpeg_video = ffmpeg.input(self.video_title)
            ffmpeg_audio = ffmpeg.input(self.audio_title)
            output_ffmpeg_title = './videos/' + self.youtube_title
            #Merging with ffmpeg
            out = ffmpeg.output(ffmpeg_video, ffmpeg_audio, output_ffmpeg_title, vcodec='copy', acodec='aac')
            out.run


  


  Here's the full code :

  If there is a better way of integrating ffmpeg with youtube-dl in Python, please tell me.

  


• Discord.py : Access files on the computer of the person who sent a message. Play a song from the local drive of any user on the server

  7 avril 2021, par daDib

  I have a bot that can play music from my computer. Is there a way to play a song from the computer of the person who sent the message ? My thought would be using message.author to somehow access the person's session and get into their drive. Here is my bot. It can join a voice channel, create playlists from local file paths, start a playlist or individual file with stop/pause/play/next/previous controls :

logger = logging.getLogger('discord')
logger.setLevel(logging.DEBUG)

handler.setFormatter(logging.Formatter('%(asctime)s:%(levelname)s:%(name)s: %(message)s'))
logger.addHandler(handler)

client = discord.Client()
commands = [
    '!connect\nConnect to a voice channel by channel id. Use !channels to find the desired id.\nExample Command: !connect 827202170973323305\n\n',
    '!channels\nLists all voice channels and their connection id.\n\n',
    '!add\nAdd a file path to the playlist.\nExample Command: !add D:\\DnD\\DiscordBot\\mySong.mp3\n\n',
    '!delete\nDeletes the last song added to the playlist.\n\n',
    '!view\nDisplays the current playlist, in order.\n\n',
    '!playlist\nStarts the playlist from the beginning, or optionally add a number as the start position.\nExample Command: !playlist 3\n\n',
    '!playSong\nPlays a specified file.\nExample Command: !playSong D:\\DnD\\DiscordBot\\mySong.mp3\n\n',
    '!next\nPlays next song in playlist.\n\n',
    '!prev\nPlays previous song in playlist.\n\n',
    '!stop\nStops all music song. Playlist will restart from the beginning.\n\n',
    '!pause\nPauses the current song. Restart with !resumeSong.\n\n',
    '!resume\nResumes the current song.\n\n'
    '!status\nLets you know if the bot thinks it is playing music.'
