Error Unable To Prefetch Com.sun.media.content.audio.midi
midi enabled application I have. The error occurs when I try and realize() the player. After about 3 seconds I get Error: Unable to prefetch com.sun.media.content.audio.midi.Handler$MidiContr oller@c3c749 my code is public class form1 extends javax.swing.JFrame { File fp = new File("C:/TEST.MID"); Player player; /** Creates new form form1 */ public form1() { initComponents(); this.setVisible(true); if (!fp.exists()) return; try { player=Manager.createPlayer(fp.toURL()); } catch (MalformedURLException ex) { ex.printStackTrace(); } catch (NoPlayerException ex) { ex.printStackTrace(); } catch (IOException ex) { ex.printStackTrace(); } player.addControllerListener( new ControllerListener() { public void controllerUpdate( ControllerEvent ce) { if ( ce instanceof RealizeCompleteEvent) { Component visual = player.getVisualComponent(); Component control = player.getControlPanelComponent(); if (visual != null) getContentPane().add(visual); getContentPane().add(control); pack(); player.start(); } } }); player.realise(); // here's where it says it can't preload sun...midi etc } any help would be appreciated Andrew Thompson (01-08-07, 07:15 PM) SlowLearner wrote: ... > my code is .. ...rubbish. That mess does not even compile. Post something that compiles* (and preferably a link to the problem MIDI as well) & I might look at it further. * For tips, see..
work so tonight I remember the jmstudio that comes with jmf. So I tried playing several midi files and jmstudio comes up with the same error message as my own code at runtime. Unable to prefetch. I've installed jmf on all 3 of my machines and sun's own program isn't able to play any http://www.experchange.com/confusing-error-during-realize-of-mediaplayer-t4108498 of what must be over 30 midi files I've tried. Many of which are in midi 1.0 standard. If somebody could run the latest version of JmStudio and try a playing a midi file for me I'd be grateful to know if it played or not. http://coding.derkeiler.com/Archive/Java/comp.lang.java.programmer/2007-01/msg00936.html The exception JmStudio reports is "Unable to prefetch" this is almost certainly the same exception my own code hits which is Error: Unable to prefetch com.sun.media.content.audio.midi.Handler$MidiController@1a7bf11 If JmStudio is able to play midi files still, could anyone suggest how to fix my install. I've already tried a total re-install of everything on one machine and it made no difference Thanks in advance M . Cranna . Follow-Ups: Re: does (jmf 2.1.1e) still support midi playback?

This Site Careers Other all forums Forum: Other JSE/JEE APIs Canot play an mp3 file using Java Media Framework (JMF) Krishna Komarpant Greenhorn Posts: 15 posted 7 years ago Hi, I have a VOIP program wherein when an incoming call is detected my java program picks the call and makes the caller listen to an audio. The audio message file format currently supported is .wav but i need to enable .mp3 support and not .wav (However additional support for .wav wuold be a plus point though. but .mp3 is a must.) When i give the path of the .mp3 file in the code of my java program, the call gets picked but nothing is played. The following is the output in the jmf.log with some errors. and below that is the output with .wav audio file. ## Building flow graph for: file:///D:\audio_message.mp3 ## Building Track: 0 ## Input: mpegaudio, 44100.0 Hz, 16-bit, Stereo, LittleEndian, Signed, 20000.0 frame rate, FrameSize=11264 bits ## Custom options specified. ## A custom codec is specified: com.sun.media.codec.audio.ulaw.Packetizer@9980d5 ## An output format is specified: ULAW/rtp, 8000.0 Hz, 8-bit, Mono, FrameSize=8 bits ## An output content type is specified: RAW/RTP XX Failed to build a graph for the given custom options.
