mrec = new MediaRecorder();  
mCamera.unlock();

mrec.setCamera(mCamera);

mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);

CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_480P);

mrec.setOutputFormat(profile.fileFormat);
mrec.setVideoFrameRate(profile.videoFrameRate);
mrec.setVideoSize(profile.videoFrameWidth, profile.videoFrameHeight);
mrec.setVideoEncodingBitRate(profile.videoBitRate);
mrec.setVideoEncoder(profile.videoCodec);
mrec.setPreviewDisplay(surfaceHolder.getSurface());
mrec.setOutputFile("/sdcard/sample.3gp");

mrec.prepare();
mrec.start();
