和录音功能的实现


try
{
// Create a DataSource that
captures live audio.
Player p = Manager.createPlayer
("capture://audio");
p.realize();
// Get the RecordControl,
set the record location, and
// start the Player and
record for 5 seconds.
RecordControl rc =
(RecordControl)p.getControl
("RecordControl");
rc.setRecordLocation
("file:/tmp/audio.wav");
rc.startRecord();
p.start();
Thread.currentThread()
.sleep(5000);
p.stop();
rc.stopRecord();
rc.commit();
} catch (IOException ioe)
{
} catch (MediaException me)
{
} catch (InterruptedException e)
{
}




实现摄像功能


Player p;
VideoControl vc;

// initialize camera
try {
p = Manager.createPlayer
("capture://video");
p.realize();

// Grab the video control
and set it to the current
display.
vc = (VideoControl)p.getControl
("VideoControl");
if (vc != null)
{
Form form =
new Form("video");
form.append((Item)vc.initDisplayMode
(vc.USE_GUI_PRIMITIVE, null));
Display.getDisplay(midlet).setCurrent(form);
}

p.start();

} catch (IOException ioe)
{
} catch (MediaException me)
{
}

// now take a picture
try {
byte[] pngImage =
vc.getSnapshot(null);

// do something with the image ...
} catch (MediaException me)
{
}
