Posted By: routed $sound().tag bug, Khaled please look - 29/09/06 09:27 PM
Found a bug in $sound().tag, not sure what's causing it, but in some mp3's it will not list all the tags... using your alias from help, I notice that it seems to halt after finding an APIC tag (assuming it's the last tag?). If you wish, I can show you my code for finding tags in ID3v2 files if that would help fild the problem.

Also, why I am at it, $sound(file,n).tag when targeting an APIC tag is not echo'able because it is assigned the entire length of the image. Can this possibly be changed to assign the binary info to a &binvar and showing the image/jpg info when finding an APIC tag?

Modified code from help to bypass APIC...

Code:
alias showtags {
  if ($1- == $null) { echo 2 -e * /showtags: please specify filename, eg. /showtags file.mp3 | halt }
  echo -a id3: $sound($1-).id3
  echo -a tags: $sound($1-).tags
  echo -a filename: $1-
  var %n = $sound($1-,0).tag
  dec %n
  while (%n > 0) {
    echo -a tag: %n $sound($1-,%n).tag
    dec %n
  }
}


Output...

Code:
id3: v2.3.0
tags: TENC WXXX TCOP TOPE TCOM COMM PCNT PCNT PCNT APIC
filename: C:\mp3\2 Pac - Changes.mp3
tag: 9 PCNT
tag: 8 PCNT
tag: 7 PCNT
tag: 6 COMM eng Rappy's TOYZ
tag: 5 TCOM
tag: 4 TOPE
tag: 3 TCOP
tag: 2 WXXX
tag: 1 TENC


Tags 1,2,3,4,5,7,8 and 9 are blank...

My scripts output for this same file...

Aside from your APIC not being echo'd... my script found several other tags AFTER the APIC tag... APIC was found at 147 bytes, which is the last tag your $sound().tag found, then TYER is at 20,269 bytes...

Hope this helps find the problem, if you wish I can reply with the code I wrote to find the tags.
