Media Recorder with HEVC encoding

Hello,

When I set videoEndoderto HEVC mediarecorder.start() is not working below is the exception. Kindly let me know the reason or whats going wrong.

{

    // BEGIN_INCLUDE (configure_preview)
    mCamera = CameraHelper.getDefaultCameraInstance();

    // We need to make sure that our preview and recording video size are supported by the
    // camera. Query camera to find all the sizes and choose the optimal size given the
    // dimensions of our preview surface.
    Camera.Parameters parameters = mCamera.getParameters();
    List<Camera.Size> mSupportedPreviewSizes = parameters.getSupportedPreviewSizes();
    List<Camera.Size> mSupportedVideoSizes = parameters.getSupportedVideoSizes();
    Camera.Size optimalSize = CameraHelper.getOptimalVideoSize(mSupportedVideoSizes,
            mSupportedPreviewSizes, mPreview.getWidth(), mPreview.getHeight());

    // Use the same size for recording profile.
    CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
    profile.videoFrameWidth = optimalSize.width;
    profile.videoFrameHeight = optimalSize.height;

    // likewise for the camera object itself.
    parameters.setPreviewSize(profile.videoFrameWidth, profile.videoFrameHeight);
    mCamera.setParameters(parameters);
    try {
            // Requires API level 11+, For backward compatibility use {@link setPreviewDisplay}
            // with {@link SurfaceView}
            mCamera.setPreviewTexture(mPreview.getSurfaceTexture());
    } catch (IOException e) {
        Log.e(TAG, "Surface texture is unavailable or unsuitable" + e.getMessage());
        return false;
    }
    // END_INCLUDE (configure_preview)

    // BEGIN_INCLUDE (configure_media_recorder)
    mMediaRecorder = new MediaRecorder();

    // Step 1: Unlock and set camera to MediaRecorder
    mCamera.unlock();
    mMediaRecorder.setCamera(mCamera);

    // Step 2: Set sources
    mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT );
    mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    mMediaRecorder.setVideoSize(1280,720);
    mMediaRecorder.setVideoEncodingBitRate(1500);
    mMediaRecorder.setVideoFrameRate(30);
    mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.HEVC);
    mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
    // Step 3: Set a CamcorderProfile (requires API Level 8 or higher)

// mMediaRecorder.setProfile(profile);

    // Step 4: Set output file
    mOutputFile = CameraHelper.getOutputMediaFile(CameraHelper.MEDIA_TYPE_VIDEO);
    if (mOutputFile == null) {
        return false;
    }
    mMediaRecorder.setOutputFile(mOutputFile.getPath());

    // END_INCLUDE (configure_media_recorder)

    // Step 5: Prepare configured MediaRecorder
    try {
        mMediaRecorder.prepare();
    } catch (IllegalStateException e) {
        Log.d(TAG, "IllegalStateException preparing MediaRecorder: " + e.getMessage());
        releaseMediaRecorder();
        return false;
    } catch (IOException e) {
        Log.d(TAG, "IOException preparing MediaRecorder: " + e.getMessage());
        releaseMediaRecorder();
        return false;
    }
    return true;
