Problem with playing mp3 files

[giaviv]

Hey guys,

I am developing a J2ME MIDlet for a S40 device (Nokia 6212).
My MIDlet needs to play a mp3 file every once in a while. This is my code that plays the file from the resource:

protected Player m_player = null;

public void playMP3Sound(String file_name) {
if (null != m_player) {
m_player.deallocate();
}
try {
InputStream in = getClass().getResourceAsStream(file_name);
m_player = Manager.createPlayer(in,"audio/mpeg");}
catch(Exception e) {
return;
}
try
{
m_player.prefetch();
m_player.start();
}
catch(Exception e){
}
}

This code works. The problem is that after around 40 files (they are all around 10-20 KB in size and around 1-2 seconds in duration) are being played, the application throws
an OutOfMemory exception and exits. Can someone see anything wrong with my code? Anything that needs
deallocation?

Thanks a lot!

Hello, try this code:



try to close the player, set up null and call System.gc().
if (null != m_player) {
m_player.close();
m_player = null;
System.gc(); //can help to free memory
}

Hey,

Thanks again for your help.
The following:
String result = System.getProperty("audio.encodings"); //return all audio supported by device
return audio/amr.
I'm trying to convert my mp3 files to AMR. I tried using several converters and the files lose volume in the process (you can barely hear the sound). What is a good mp3 to amr conversion program?
When I create the player, which encoding should I use (to replace the audio/mpeg)? is it audio/amr?

Thanks again.

Hi,

When you are converting the Mp3 files to AMR you will surely gona loose on the sound quality and voice. This is the only reason due to which AMR files are much lighter the MP3. But you can try "switch mp3 converter"
