POProblem with Video recording after auto focus in Android
text
Body
copied!<p>Im trying to build an app which tries to auto focus the camera before starting the video recording. Directly using <code>MediaRecorder</code> does not auto focus the camera. For that i am Using <code>Camera</code> and using the callback I can autofocus it. But providing this instance to the <code>MediaRecorder</code> gives me a lot of issues. Following is the code im using for recording</p> <pre><code>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; } } </code></pre> <p>The Camera attributes are as follows:</p> <pre><code>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(); </code></pre> <p>All this is giving me the following error message:</p> <pre><code> 11-22 16:51:25.314: DEBUG/Preview(4052): !!!!!!!!!!111Starting recording!!!!!!!!!!!!!!
