B4J Question [SOLVED] Playing mp3 in Ubuntu / Debian

[aberezhnykh]

I have an application that works well on Windows and Mac. I'm trying to run the application on Ubuntu / Debian, but the attempt was not successful. I found that the codecs for mp3 are problematic. For example, I made a simple code that ends with an error. Is there a solution to this problem? Thank you!

#Region Project Attributes
    #MainFormWidth: 600
    #MainFormHeight: 600
#End Region

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
'    MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
    MainForm.Show
    Dim mediaPlayer As MediaPlayer
    Dim url As String = "http://ol3.mp3party.net/online/3401/3401743.mp3"
    mediaPlayer.Initialize("mediaPlayer", url)
    mediaPlayer.Play
End Sub

'Return true to allow the default exceptions handler to handle the uncaught exception.
Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
    Return True
End Sub

Result:

Presumably you need to install the correct codec for Ubuntu.

Alternatively you could make sure that the mp3 is encoded in a format that the mediaplayer already has a codec for.

Did you encode the mp3? Do you know what format it is? It sounds like it is not a standard format

Have you tried any other MP3's?

Thanks for the answer! I found some information about this https://bugs.openjdk.java.net/browse/JDK-8147888. For two days I have been trying unsuccessfully to solve this problem. I've tried several files from different sources, but without success.

The problem is solved!
From the site http://www.ubuntuupdates.org was downloaded and installed manually the packages libavutil51, libavformat53, libavcodec53, and a package libvpx1. Now everything is fine!
