Question

MP3 player for resized data

Asked by: hlominac

I used MP3Resizer to resize a 44,100 Hz 16 bit file to 22,050 Hz 16 bit file.
I use Windows Media Player 11 (wmplayer.exe) to play the original file but it will not play the resized file.  I expect I am not using the same codec used by MP3Resizer.  If this is the case, what codec do I use and how do I install it in my VB.Net program?  I use  ShellProc to run the Media Player.

Yes, it looks like a codec problem. Media Player uses all codecs installed in your machine, I don't know how MP3Resizer works. Try other program to do it like Super: http://www.erightsoft.com/SUPER.html, it is freeware.

 

by: hlominacPosted on 2009-11-02 at 05:54:31ID: 25719246

Super seems to resize similar to MP3Resizer and is slow. I have already converted hundreds of files, so Super is not the answer.  If I use Media Player directly the files will play.  Also Sony Sound Forge will play them.  But I cannot play through my program.

 

by: sedgwickPosted on 2009-11-02 at 06:40:25ID: 25719695

do u wish to play the mp3 from your program WITHOUT running the Media Player or the Sony Sound Forge player?

What does your program use to play it? Direct Show?

 

by: hlominacPosted on 2009-11-02 at 08:02:54ID: 25720567

I wish to play with WIndows Media Player.  See the code snippet.
I did not find how tu use Direct Show.
The error is: Windows Media Player cannot find the file....etc.
In the code snippet:
ProgFiles = "C:\Program Files"
The Filename = "C:\Program Files\Windows Media Player\wmplayer.exe"
Hold = "D:\Sermons\The Road Back to Hope.mp3"
Again this is 22,050 Hz 16 bit
44,100 Hz 16 bit does not have an error.
I hope this might help you.

Sorry - the code did not go through.

   Private Sub RTB_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RTB.MouseUp
      Dim Hold As String = sender.selectedtext
      If StrComp(Path.GetExtension(Hold), ".mp3", CompareMethod.Text) = 0 Then
         Dim ShellProc As New Process
         Dim ProgFiles As String = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles)
         ShellProc.StartInfo.FileName = ProgFiles & "\Windows Media Player\wmplayer.exe"
         ShellProc.StartInfo.Arguments = Hold
         ShellProc.Start()
         ShellProc.Close()
      End If
   End Sub 'RTB_MouseUp

>> Windows Media Player cannot find the file

Is a message that is not symptomatic of a codec problem. If you can play the file normally (by say double-clicking the MP3 file in the Explorer and watching WMPlayer come to life) then the codeic is not at the heart of the problem.

You need to figure out why your program is getting the filename incorrect. Put up a messge box displaying the variable named Hold. It probably has some bad data in it. Another thing to try is surround the filename of the MP3 file with quotes.

"Another thing to try is surround the filename of the MP3 file with quotes."
This fixed the problem!
ShellProc.StartInfo.Arguments = "" & Hold & ""
