• How to batch downsample alac files using ffmepg ? [closed]

  1er octobre 2022, par A meme

  So I've got a libarary of songs I wan to throw on an Ipod photo I modified flash modded, sadly due to the fact I want to stick to iTunes for syncing I cant import some of my alac's due to their sample rate being at 88200Hz, I've read that the iPod can only handle up to 48000hz but I can't figure how to make a simple single line lookup script to just downsample them all in one go.

  


  I've tried :

  


  find . -type f -name '*.m4a' -print -exec sh -c 'i="{}"; ffmpeg -i "$i" -compression_level 12 [-ar 48000 -sample_fmt 16] "$i"\; 


  


  but it just blinks the cursor and trying

  


  ffmpeg -i <my song="song"> -compression_level 12 [-ar 48000 -sample_fmt 16] <my output="output">&#xA;</my></my>

  


  gave me an error of failed to convert
I also tried sox but it doesn't have a handler for .m4a which is what alac is.

  


• I cannot play a mp3 file on Discord's voice channel using discord.py

  1er décembre 2024, par ra1ned

  I am creating a discord bot that plays lofi for me. It does not play a song for me even though it shows a green indicator on a voice channel.

  


  Here's what I've written :

  


  if message.content == "!join":
    await message.author.voice.channel.connect()
    await message.channel.send("Successfully connected")

if message.content == "!play":
    if message.guild.voice_client is None: 
        await message.channel.send("use !join")
        return
    
    await message.channel.send("playing a song rn")
    print('*** playing a song rn')
    
    message.guild.voice_client.play(discord.FFmpegPCMAudio('lofi.mp3'))


  


  I put FFmpeg.exe and lofi.mp3 in the same directory as this script.
Also, it is strange that FFmpeg does not return any exception nor output on console although it seems to have failed to load the file. I have seen people who had the same problem, but it seems like that they get some error messages, unlike me.

  


  Here's the output on console after using !join

  


  2024-12-01 16:59:39 INFO     discord.voice_state Connecting to voice...
2024-12-01 16:59:39 INFO     discord.voice_state Starting voice handshake... (connection attempt 1)
2024-12-01 16:59:40 INFO     discord.voice_state Voice handshake complete. Endpoint found: japan8946.discord.media
2024-12-01 16:59:40 INFO     discord.voice_state Voice connection complete.


  


  after using !play, it only displays the message I wrote :

  


  *** playing a song rn


  


  Can someone help me with this ?

  


• Convert video to mp3 with album art with ffmpeg

  30 mars 2014, par dave

  Using ffmpeg, I want to extract only the audio of a video and turn it to an mp3, in addition, I want to add some meta information including an image to the mp3.

  I can do each of these separately.

  First, extracting the audio :

  fmpeg -i video.mp4 -f mp3 -vn -b:a 192k -ac 2 -ar 44100 -aq 5 -y out.mp3

  Second, add the image and meta info :

  ffmpeg -i out.mp3 -i image.jpg -map 0:0 -map 1:0 -c copy -id3v2_version 3 -metadata:s:v title="Song Title" -metadata:s:v comment="This Song" -c:a:0 -y out2.mp3

  What I'd like to do however is have this in a single command. This is the question. How do I combine these two into a single workable command (if possible). When I try to combine them, I get issues with no input streams.

  Thank you !
