• KeyError :

  26 juin 2022, par Leon Warta

  So i get the "KeyError: " error, in my code for a music bot (Discord). it says the problems lays in this part : url2 = info['format'][0]['url']

  


  this is the code ;

  


  @client.command()
async def play(ctx, url):
    ctx.voice_client.stop()
    FFPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    YDL_OPTIONS = {'format': 'bestaudio', 'default-search': "ytdlsearch"}
    vc = ctx.voice_client

    with youtube_dl.YoutubeDL(YDL_OPTIONS) as ydl:
        info = ydl.extract_info(url, download=False)
        url2 = info['format'][0]['url']
        source = await discord.FFmpegOpusAudio.from_probe(url2, **FFPEG_OPTIONS)

        vc.play(source)


  


  edit ; im new to coding so if you explain, just use easy words.
edit ; thnx to Infinity ! you're a legend ! I was struggling with this code for 2 days, bc i missed one "s" in my code.....

  


• Anomalie #4623 : Styles des fieldset dans l’espace privé

  19 avril 2021, par nicod _

  Pour info j’ai travaillé sur le regroupement des radios et checkbox dans des fieldsets :
  https://git.spip.net/spip-contrib-extensions/saisies/pulls/105

  Pour l’instant, ça ne fait que mettre un fieldset à la place du div comme contenur, et un legend à la place de label, ça génère donc un simple fieldset.editer :

• Adding album cover art to FLAC audio files using `ffmpeg`

  27 décembre 2022, par user5395338

  I have ripped files from an audio CD I just bought. I ripped using the Music app on my Macbook Pro, Catalina 10.15.6 - output format was .wav as there was no option for FLAC. My plan was to change format using ffmpeg :

  


  % ffmpeg -v
ffmpeg version 4.4 Copyright (c) 2000-2021 the FFmpeg developers


  


  Except for the "album cover artwork" addition, the .wav-to-.flac conversion implemented in the short bash script below seems to have worked as expected :

  


  #!/bin/bash
for file in *.wav
do
echo $file 
ffmpeg -loglevel quiet -i "$file" -ar 48000 -c:a flac -disposition:v AnotherLand.png -vsync 0 -c:v png "${file/%.wav/.flac}"
done


  


  A script very similar to this one worked some time ago on a series of FLAC-to-FLAC conversions I had to do to reduce the bit depth. However, in that case, the original FLAC files already had the artwork embedded. Since this script produced usable audio files, I decided that I would try adding the artwork with a second ffmpeg command.

  


  I did some research, which informed me that there have been issues with ffmpeg (1, 2, 3, 4) on adding album artwork to FLAC files.

  


  I have tried several commands given in the references above, but still have not found a way to add album artwork to my FLAC files. The following command was a highly upvoted answer, which I felt would work, but didn't :

  


  % ffmpeg -i "01 Grave Walker.flac" -i ./AnotherLand.png -map 0:0 -map 1:0 -codec copy -id3v2_version 3 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (front)" output.flac

...


Input #0, flac, from '01 Grave Walker.flac':
  Metadata:
    encoder         : Lavf58.76.100
  Duration: 00:06:59.93, start: 0.000000, bitrate: 746 kb/s
  Stream #0:0: Audio: flac, 48000 Hz, stereo, s16
Input #1, png_pipe, from './AnotherLand.png':
  Duration: N/A, bitrate: N/A
  Stream #1:0: Video: png, rgba(pc), 522x522, 25 fps, 25 tbr, 25 tbn, 25 tbc
File 'output.flac' already exists. Overwrite? [y/N] y
[flac @ 0x7fb4d701e800] Video stream #1 is not an attached picture. Ignoring
Output #0, flac, to 'output.flac':
  Metadata:
    encoder         : Lavf58.76.100
  Stream #0:0: Audio: flac, 48000 Hz, stereo, s16
  Stream #0:1: Video: png, rgba(pc), 522x522, q=2-31, 25 fps, 25 tbr, 25 tbn, 25 tbc
    Metadata:
      title           : Album cover
      comment         : Cover (front)
Stream mapping:
  Stream #0:0 -> #0:0 (copy)
  Stream #1:0 -> #0:1 (copy)

...



  


  I don't understand the error message : Video stream #1 is not an attached picture. It seems to imply that that the artwork is "attached" (embedded ???) in the input file, but as I've specified the artwork is a separate file, this makes no sense to me.
