Android Media Recorder Mirrored Mirror Output

Question

I am creating an application that can record video, but the output is mirrored, which annoys me. The preview is perfect, but when I play a video from a video review, it is mirrored (also saved as a mirror image).

This is my code for setting up Mediarecorder, which I use.

    mediaRecorder = new MediaRecorder();
    mediaRecorder.setPreviewDisplay(holder.getSurface());
    mediaRecorder.setCamera(camera);
    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    mediaRecorder.setVideoSize(640, 480);
    mediaRecorder.setOrientationHint(270);
    mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
    mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC_ELD);
    mediaRecorder.setMaxDuration(50000);

Thanks in advance.
