Comment #3 by Federico ALLEGRETTI:

after some trials with this testing code:
' Gambas class file

Public player As MediaPlayer
Public uscita As MediaControl

Public Sub Form_Open()
  
  player = New MediaPlayer
  uscita = New MediaControl(player, "fakesink")
  player.Audio.Output = uscita
  player.URL = Media.URL("path_to_the_mp3_song")
  
  player.Play 
  While player.Duration = 0
    Wait 0.1
  Wend
  
  Print player.Duration
  player.Stop
  
End

i found there was some weird error in the mp3 coding.

with the original bad.mp3 song, loop never exit, but if i fix the mp3 with:

ffmpeg -i bad.mp3 -c:a copy good.mp3

than the test code with "good.mp3" reports correct lenght.

Strange thing is that (using autoaudiosink) gstreamer plays back both bad.mp3 and good.mp3

attached are bad.mp3 and converted good.mp3
