java - Issues with playing sounds on the BlackBerry -

-

I am having the following problem while playing the sound on Blackberry:

  • The application is hanged for ~ 500 ms (not when the player is created, when the sound is actually played)
  • There is a delay rather than the call and the voice

I tested on a physical device other than the simulator. On the simulator, there should be a bug, because this v Seconds before the car starts (I've heard that it is a problem with the simulator, so ...).

I have also tested. Wav vs mp3 files, and it gives pretty much the same results.

Here is the code I use to load a player: 

  stream = new object (). GetClass () GetResourceAsStream (fileName); Results = javax.microedition.media.Manager.createPlayer (stream, fileName.endsWith (".wav")? "Audio / x-wave": "audio / mpeg"); If (prefetch) {result.prefetch (); }

I then store the player reference, which I use to run the sound with the following code: 

  javax.microedition. Media.player player = (Javax.microedition.media.Player) resource [soundId]; If (player! = Null) {// # debug System.out.println ("Player state:" + .getState (+) player;); If (player .getState ()! = Javax.microedition.media.Player.STARTED) {player.setLoopCount (LoopCount); Player.start (); }}

I feel positive that due to delay the sound is playing because I have a switch to close it and when I do this the delay is gone. Is there something I am doing wrong?

Updates

Nothing worked, so I stopped changing the sound into MIDI files which are handled better if any solution Finds, even then I would like to hear it.

There is no good solution for the problem, but how to reduce it:

  • Create a separate thread to run sounds (this is a thread that will call players. Start (), because this
  • if your game's frame rate is too high and As a result you are using 100% CPU, then the media player will not have enough time to prepare the buffer between the frame, For help, it will take a long time to run. Reduce the frame rate slightly to help.
  • At the developer conference, RIM showed the code for a wave mixer, a player joining the incoming sound files in the stream. Keeping open should fix the problem, although they have not released the code yet.
  • On OS7, under high CPU load, mess with MIDI file frame rate, so avoid it. < / Li>

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
