Android CWAC摄像头：前置摄像头的图像始终镜像

Question

I am using CWAC's camera in an app. Although the demo app seems to work the way I need it to - ie the image from the front facing camera is not mirrored if I return true from mirrorFFC() in DemoCameraHost.

@Override
 public boolean mirrorFFC() {
    return true;
}

When I do the exact same thing in my app, for some reason the image from the front facing camera is still mirrored. Clearly I am missing something out, although I am finding it hard to put my finger on it. I have even passed true to the SimpleCameraHost builder in the onCreate of my Camera Fragment class as shown below.

cameraHost = new MyCameraHost(getActivity(), useFFC);
    SimpleCameraHost.Builder builder =
            new SimpleCameraHost.Builder(cameraHost).mirrorFFC(true);
    setHost(builder.useSingleShotMode(true).mirrorFFC(true).build());

Answer 1

Turns out the reason this was happening was I was returning 0.0f from maxPictureCleanupHeapUsage() in my custom camera host. I changed it back to 1.0f and this seems to have fixed the problem.
