如何在录制时添加对视频的过滤以及在android中保存之后...？

mediaRecorder = new MediaRecorder();

        mCamera.unlock();
        mediaRecorder.setCamera(mCamera);

        mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
        mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

        mediaRecorder.setProfile(CamcorderProfile
                .get(CamcorderProfile.QUALITY_LOW));
        // mediaRecorder.setVideoEncodingBitRate(690000);
        mediaRecorder.setVideoEncodingBitRate(6000000);
        // mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
        // mediaRecorder.setOutputFile("/sdcard/Movie.mp4");

        demoVideoFolder = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/videokit/";
        demoVideoPath = demoVideoFolder + "in.mp4";
        // Toast.makeText(getApplicationContext(), ""+demoVideoFolder,
        // 56).show();

        File storagePath2 = new File(demoVideoFolder);
        storagePath2.mkdir();

        mediaRecorder.setOutputFile("/sdcard/videokit/in.mp4");
        rotateBackVideo(mediaRecorder);

        try {
            mediaRecorder.prepare();
        } catch (IllegalStateException e) {
            releaseMediaRecorder();

        } catch (IOException e) {
            releaseMediaRecorder();

        }

我想在使用MediaRecorder录制时在我的视频中添加多个滤镜,并在保存的视频后添加滤镜.如何实现第二种情况..？
