• Convert m4a to aac and keep metadata on Windows 7

  24 novembre 2014, par betamax

  I want to convert an m4a file to aac*. I can do this using :

  ffmpeg -i song.m4a -acodec copy song.aac

  But on Windows 7 the metadata is not compatible. It seems the -id3v2_version 3 flag should be used so that Windows compatible ID3 tags version 2.3 are used :

  ffmpeg -i song.m4a -acodec copy -id3v2_version 3 song.aac

  However, with the above command I still don’t get any metadata in song.aac. I have used windows file explorer, mp3tag and winamp to confirm there are no tags.

  * : reason ; m4a won’t play on the car stereo so following this advice (http://www.vwaudiforum.co.uk/forum/showthread.php?153728-Tip-Getting-M4A-(iTunes)-format-music-to-play-on-a-VW-head-unit)

  Console Output :

  C:\temp>ffmpeg -i song.m4a -acodec copy -id3v2_version 3 song.aac

• My music doesn't play correctly and other problems - Discord.py

  24 mars 2021, par Diacono

  So, I'm triying to let my bot play songs directly from the url (without downloading them like the song.mp3 method) but I'm having a hard time. The bot plays only 1 song and when I try to play another song it doesn't play it.
I'm also getting 2 errors : video_link is not defined and self is not defined.
Also when I try to play live music like "lofi hip hop radio - beats to relax/study to" nothing happens.
Can you help me please ???

• Discord music bot doesn't play songs

  I have made myself a discord bot that also plays music(it's only for my server so strings with messages are in Czech, but code is in English).
Bot worked a while ago but now it stopped, and I don't know where the problem is

  I already tried everything I can think of(which isn't a lot because I suck at programming), and also tried searching for some solution on the internet, but nothing worked.
