SOLVED: Not sound on playing mp3 from resource
« on: March 13, 2020, 07:12:51 pm »
Hello coders :)
I am trying to play a mp3 file from Laz resources but it does not work, like if it is muted.
Any help will be appreciated.

Greetings.

Code: Pascal  [Select][+][-]
  1. //The .mp3 file is type RCDATA, called MYSOUND in project options.
  2. var
  3.   S: TResourceStream;
  4. begin
  5.   S := TResourceStream.Create(HInstance, 'MYSOUND', RT_RCDATA);
  6.   try
  7.     PlaySound('MYSOUND', 0, SND_RESOURCE);
  8.   finally
  9.     S.Free;
  10.   end;

Hi!

PlaySound is only for wav files:

Code: Text  [Select][+][-]
  1. The object is to play a simple WAV sound both in Windows and Linux (Sync and ASync)

Note also that PlaySound() already implements the code needed to get to the ressource, so you don't need to create a resource stream. And, IIRC (sorry, has been years since I actively developed on Windows) you should pass to it the instance handle of the application.

All in all it should be just something like:

Code: Pascal  [Select][+][-]
  1. begin
  2.   if not PlaySound('MYSOUND', Application.Handle, SND_RESOURCE or SND_ASYNC) then
  3.     ShowMessage('Can''t play "MYSOUND"');
  4. end;

But as Winni said, AFAIR PlaySound() can only deal with RT_WAVE resources, not with generic RT_DATA ones.

Take all this, with a pinch of salt: I left Windows behind (except for testing) with the release of Vista ;)

Is the issue before
"Hello darkness, my old friend
I've come to talk with you again
Because a vision softly, creeping
Left its seeds while I was, sleeping
And the vision, that was planted in my brain... still remains
Within the sound of silence¨ or after? :-\
I am more like donkey than shrek

I found a way to play a .wav file without any component. It works great!
Tested in a blank document.

Add the file as RCDATA in Project > Options > Resources.

Code: Pascal  [Select][+][-]
  1. //Needed in uses section
  2. uses
  3.   Windows, MMSystem;
  4.  
  5. //...
  6.  
  7. procedure TForm1.Button1Click(Sender: TObject);
  8. var
  9.   S: TResourceStream;
  10. begin
  11.   S := TResourceStream.Create(HInstance, 'DOORBELL', RT_RCDATA);
  12.   try
  13.     S.Position := 0;
  14.     SndPlaySound(S.Memory, SND_MEMORY or SND_ASYNC);
  15.   finally
  16.     S.Free;
  17.   end;
  18. end;

 ;)

Lazarus is awesome.
The more you learn it the more you will like it.
