Also irgendwie komm ich grad nicht weiter ...
Mein bisheriger Code schaut wie Folgt aus:
Java
public class MainActivity extends Activity implements SurfaceHolder.Callback {
private Camera camera = null;
private SurfaceView surface = null;
private SurfaceHolder holder = null;
private MediaRecorder recorder = new MediaRecorder();
private boolean isRecording = false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Camera.CameraInfo info = new CameraInfo();
LinearLayout ll = (LinearLayout) findViewById(R.id.llButtons);
for (int i = 0; i < Camera.getNumberOfCameras(); i++) {
Camera.getCameraInfo(i, info);
Button b = new Button(this);
if (info.facing == CameraInfo.CAMERA_FACING_BACK) {
b.setText("Rückseite");
} else {
b.setText("Vorderseite");
}
b.setOnClickListener(new MyClickListener(i));
ll.addView(b);
}
}
private class MyClickListener implements View.OnClickListener {
private int cam = -1;
public MyClickListener(int i) {
this.cam = i;
}
@Override
public void onClick(View v) {
if (camera != null) {
camera.stopPreview();
camera.release();
}
camera = Camera.open(cam);
camera.setDisplayOrientation(90);
if (surface != null) {
holder.removeCallback(MainActivity.this);
holder = null;
surface.destroyDrawingCache();
surface = null;
}
surface = new SurfaceView(MainActivity.this);
LinearLayout llSurface = (LinearLayout) findViewById(R.id.llSurface);
llSurface.removeAllViews();
llSurface.addView(surface);
holder = surface.getHolder();
holder.addCallback(MainActivity.this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
if (holder.getSurface() == null || surface == null) {
return;
}
camera.stopPreview();
try {
camera.setPreviewDisplay(holder);
camera.startPreview();
} catch (IOException e) {
Log.e(MainActivity.class.getSimpleName(), e.getMessage());
}
}

}
break;

if (isRecording) {

}
recorder.release();
recorder = null;
break;
default:
break;
}
}
private void initRecorder() {
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);

File video = new File(Environment.getExternalStorageDirectory() + "/DCIM/");
String videoname = "test_" + System.currentTimeMillis() + ".3gp";

}
private void prepareRecorder() {

try {

} catch (IllegalStateException e) {
Log.e(MainActivity.class.getSimpleName(), e.getMessage());

05-06 11:27:12.722: I/Process(13422): Sending signal. PID: 13422 SIG: 9Ich würd mich aber eigentlich an die API halten und der Code entspricht auch den Beispielen, die ich so gefunden habe ...
ZitatSets the format of the output file produced during recording. Call this after setAudioSource()/setVideoSource() but before prepare().
Mach ich ja eigentlich ...
Hat jemand eine Idee?

EDIT:
Ich steh echt auf dem Schlauch -.- hab sogar ne Schritt für Schritt Anleitung gefunden, die eigentlich alles klärt, aber ich seh meinen Fehler nicht ... hier der Link: Camera - Capturing videos
(Arnova 9G2 ... was will man erwarten)
