Playing Audio - error: PVMFErrNotSupported (Prepare failed.: status=0x1 )

December 13th, 2009

When it comes to playing sound files in android, I've found plenty of code samples that look something like this...

try{

mp = new MediaPlayer();

mp.setDataSource(somePathToAudioFile);

mp.prepare();

mp.start();

}catch(Exception e){

}

But when I tried these samples I kept getting these errors...

PVMFErrNotSupported

Prepare failed.: status=0x1

I found that instead of passing a string into mp.setDataSource(string), I could pass in a FileDescriptor to avoid these errors. Here's a sample that worked for me (it's a few more lines of code, because you have to create a File object and a FileInputStream object in order to get the FileDescriptor object):

if(mediaPlayer != null){
mediaPlayer.release();

}
mediaPlayer = new MediaPlayer();

//in this case my sound file is in the application directory...
String audioFilePath = getFilesDir().getAbsolutePath() + File.separator + "test.mp4";

try {

    File file = new File(audioFilePath);
    FileInputStream fis = new FileInputStream(file);
    mediaPlayer.setDataSource(fis.getFD());
    mediaPlayer.prepare();
    mediaPlayer.start();

} catch(FileNotFoundException e){

} catch (IllegalArgumentException e) {

} catch (IllegalStateException e) {

} catch (IOException e) {

}

Thanks for that. I had been struggling with this for a couple of days too. My program would play a .wav file in the emulator, but not on a real Galaxy Tab. Using the above solved the problem! Cheers - K.

This solution does not work for streaming from a web URL. Any other ideas?

Thanks! Your solution worked.

The other solution from the comments of "mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);" didn't work for me.

Thanks. That's the second thing like this that was solved by simply using a different argument type.

This is really weird. I had to use the following syntax to get the player to play dcf files (OMA DRM protected music)
mp.setDataSource(new MyContext(), Uri.fromFile(file));

mp.setAudioStreamType(AudioManager.STREAM_MUSIC);

Where MyContext is an extended class of Context.

Hope this can help others.

I have found that I needed to set the audio stream type. See here. http://smartandroidians.blogspot.com/2010/06/live-audio-streaming-using-mediaplayer.html

Thanks! I've been wrestling with this for 2 days. I' running an android app with the Processing tool. Stuck at a file not found exception, cant seem to get the path but its a processing thng. At least I know if I get the path there will be no errors now!
