android - Mediarecorder start failed -19

I am getting this error when running start() for mediarecorder.

06-28 18:46:22.570: E/MediaRecorder(9540): start failed: -19
06-28 18:46:22.570: W/System.err(9540): java.lang.RuntimeException: start failed.

I am extending mediarecorder class
My code:

camera = Camera.open(cameraId);
super.setCamera(camera);
        super.setVideoSource(MediaRecorder.VideoSource.CAMERA);
        super.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
        if (mode==MODE_DEFAULT) {
            super.setMaxDuration(1000);
            super.setMaxFileSize(Integer.MAX_VALUE);
        } else {
            // On some phones a RuntimeException might be thrown :/
            try {
                super.setMaxDuration(0);
                super.setMaxFileSize(Integer.MAX_VALUE); 
            } catch (RuntimeException e) {
                Log.e(TAG,"setMaxDuration or setMaxFileSize failed !");
            }
        }
        super.setVideoEncoder(videoEncoder);
        if(surfaceHolder!=null)
        super.setPreviewDisplay(surfaceHolder.getSurface());
        //super.setVideoSize(quality.resX,quality.resY);
        super.setVideoFrameRate(quality.frameRate);
        super.setVideoEncodingBitRate(quality.bitRate);

Fixed by removing
