Hello stackoverflow friends. I am new by android and have bellow code for capturing video. But this has low quality on phone( specially on android version 4.2 has very very low quality). I need a video capture with higher quality but i dont know other attribute for this. how can I have a high quality video recorder ?
protected void startRecording() throws IOException
{
mCamera.stopPreview();
mCamera.unlock();
mrec = new MediaRecorder();
mrec.setCamera(mCamera);
mrec.setAudioSource(MediaRecorder.AudioSource.MIC);
mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mrec.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mrec.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mrec.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
mrec.setOutputFile(Videopath);
mrec.setPreviewDisplay(surfaceHolder.getSurface());
mrec.prepare();
isRecording=true;
mrec.start();
}
//-------------------------------------------------------------
protected void stopRecording()
{
releaseOnExit();
mCamera = Camera.open();
mCamera.lock();
surfaceView = (SurfaceView) findViewById(R.id.surface_camera);
surfaceHolder = surfaceView.getHolder();
surfaceHolder.addCallback(this);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Parameters params = mCamera.getParameters();
mCamera.setParameters(params);
mCamera.setDisplayOrientation(90);
try {
mCamera .setPreviewDisplay(surfaceHolder);
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
mCamera .startPreview();
btnlistToggle.setEnabled(true);
}
//-------------------------------------------------------------
@Override
public void surfaceCreated(SurfaceHolder holder)
{
if (mCamera != null)
{
Parameters params = mCamera.getParameters();
mCamera.setParameters(params);
mCamera.setDisplayOrientation(90);
try {
mCamera .setPreviewDisplay(holder);
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
mCamera .startPreview();
}
else
{
Toast.makeText(getApplicationContext(), "Camera not available!", Toast.LENGTH_LONG).show();
VideoRecorderActivity.this.finish();
}
}
Also I have a voice recorder that it has a very low quality too. what I do for upper quality voide recorder ,too?
public void Record() throws IOException
{
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(this.path);
try
{
recorder.prepare();
}
catch (IllegalStateException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
