According to the assembly code above, I succeeded in playing MP3. Now I want to ask if you can set the playing position of MP3,
such as:
Code:
senkTo ()


Maybe from the main source of code; You can access @ mgr.inz.Player.
playing MP3 files with CE (extended playSound function)

By use mgr.inz.Player MCI send command module, you need to make some additional function to get :

1. Length of MP3 file (count in times)

example :

Code:
function lengthMP3()
 if not initializeMPlayer() then return end
 local a,b=MPlayerSendCommand('status MediaFile length')
 return tonumber(b) or 0
end

2. Duration of MP3

example :

Code:
function durationMP3()
 if not initializeMPlayer() then return end
 local a,b=MPlayerSendCommand('status MediaFile length')
 return tonumber(b) or 0
end


and then make a function to 'seek' the position of MP3 as you want.

example :

Code:
function seekMP3()
 if not initializeMPlayer() then return end
 local a,b=MPlayerSendCommand('Seek')
-- in VB Net I use this :
--
-- Public Sub mmSeek(ByVal sngPosition As Single)
-- '   Seek a specific position within the file
-- Dim lngReturn As Long   '   Hold the value returned by the mciSendString function
-- lngReturn = mciSendString("Seek " & strAlias & " to " & sngPosition, "", 0, 0)
-- End Sub

// so can make it in Lua
end


For reference, please googling about 'mciSendString'

I just want to try to adjust the position of the playback schedule in a similar way to the volume adjustment function.
Code:
function seekMP3(pol)  if not initializeMP3Player() then return end  MP3PlayerSendCommand('seek MediaFile to '..pol)  end
