  23 juin 2022, par dank rainbow

  @bot.command()
async def getsong(ctx, *, songname):
    "get song in mp3 from song name"
    os.popen(f'spotdl {songname} -f "/home/pi/discordbot/output/{songname}.mp3"')

  ffmpeg installed with sudo-apt get. works if ran from terminal
how to fix ?

  


  figured it out my self.
working code if it benefits anyone :

  


  @bot.command()
async def getsong(ctx, *, songname):
    "get song in mp3 from song name"
    subprocess.Popen(f'spotdl -o "/home/pi/discordbot/output" --ffmpeg "/usr/bin/ffmpeg" {songname} --path-template "{songname}.mp3"', shell=True)
    await ctx.send(file=discord.File(fr'/home/pi/discordbot/output/{songname}.mp3'))


  


• How to convert an mp3 file to raw audio format using javascript

  4 octobre 2022, par Lord Bee

  I'm working on a project that involves song matching, so I am integrating with rapidApi's shazam endpoints. But the thing is, the song matching endpoint needs the audio snippet to be a base64 string of the audio in raw audio format. I know the API works. I downloaded a 3rd party application to do the conversion from mp3 to .raw, and converted it to base64 before making the request with it.

  


  Now, I need to integrate this flow programmatically. How do I convert an mp3 or any audio source really to a .raw file ? I've done a lot of searching but I can't find any solution.

  


• How to take metadata from .mp3 file and put it to a video as a text using FFmpeg ?

  6 décembre 2020, par Grrzly

  In my previously opened topic :

  


  How to make FFmpeg automatically inject mp3 audio tracks in the single cycled muted video


  


  I've got detailed explanation from @llogan how to broadcast looped short muted video on youtube automatically injecting audio tracks in it without interrupting a translation.

  


  I plan to enhance the flow and the next question I faced with is how to dynamically put an additional text to the broadcast.

  


  Prerequisites :

  


  

  1. youtube broadcast is up and running by ffmpeg

  


  2. short 3 min video is paying in infinity loop

  


  3. audio tracks from playlist are automatically taken by "ffmpeg concat" and injected in the video one by one

  


  


  this is a basic command to start translation :

  


  


  ffmpeg -re -fflags +genpts -stream_loop -1 -i video.mp4 -re -f concat
-i input.txt -map 0:v -map 1:a -c:v libx264 -tune stillimage -vf format=yuv420p -c:a copy -g 20 -b:v 2000k -maxrate 2000k -bufsize
8000k -f flv rtmp ://a.rtmp.youtube.com/live2/my-key

  


  


  Improvements I want to bring

  


  

  1. I plan to store some metadata in audio files (basically it's an artist name and a song name)

  


  2. At the moment a particular song starts playing artist/song name should be taken from metadata and displayed on the video as text during the whole song is playing.

  


  3. When the current song finishes and a new one starts playing the previous artist/song text should be replaced with the new one etc

  


  


  My question is how to properly take metadata and add it to the existing broadcast config using ffmpeg ?
