Проблема с записью видео после автофокуса в Android

3 голосов
/ 22 ноября 2010

Я пытаюсь создать приложение, которое пытается автоматически сфокусировать камеру перед началом записи видео. Непосредственное использование MediaRecorder не приводит к автоматической фокусировке камеры. Для этого я использую Camera и с помощью обратного вызова я могу его автофокусировать. Но предоставление этого экземпляра MediaRecorder доставляет мне много проблем. Ниже приведен код, который я использую для записи 

public boolean startRecording()
{
    try
    {
        mCamera.unlock();

        mediaRecorder = new MediaRecorder();
        mediaRecorder.setCamera(mCamera);

        mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

        CamcorderProfile profile = CamcorderProfile
                .get(CamcorderProfile.QUALITY_LOW);
        mediaRecorder.setProfile(profile);

        mediaRecorder.setMaxDuration(maxDurationInMs);

        File file = new File(outputFile);
        if (file.exists())
            file.delete();
        file = new File(outputFile);

        try
        {
            file.createNewFile();
        }
        catch (IOException e1)
        {
            // TODO Auto-generated catch block
            e1.printStackTrace();
            Log.e("Deepak", "*** first catch ***");
        }


        mediaRecorder.setOutputFile(outputFile);
        mediaRecorder.setPreviewDisplay(mHolder.getSurface());

        mediaRecorder.setMaxFileSize(maxFileSizeInBytes);

        mediaRecorder.prepare();
        mediaRecorder.start();

        return true;
    }
    catch (IllegalStateException e)
    {
        Log.e(TAG, e.getMessage());
        e.printStackTrace();
        return false;
    }
    catch (IOException e)
    {
        Log.e(TAG, e.getMessage());
        e.printStackTrace();
        return false;
    }
}

Атрибуты камеры следующие: 

Camera.Parameters parameters = mCamera.getParameters();
    List<Size> sizeList = parameters.getSupportedPreviewSizes();
    parameters.setPreviewFormat(ImageFormat.JPEG);
    parameters
            .setPreviewSize(sizeList.get(0).width, sizeList.get(0).height);
    mCamera.setParameters(parameters);
    mCamera.startPreview();

Все это выдает мне следующее сообщение об ошибке:

Это создает файл в указанном месте, который полностью затемнен, просто пучок зеленых горизонтальных линий.

Все разрешения размещены. Использование Android 2.2. Пробовал точный код как этот но все равно получил аналогичный VENC_ERROR

Вам нужно остановить предварительный просмотр перед разблокировкой камеры 

mCamera.stopPreview();

mCamera.unlock();
...
