To test 3rd option (gstreamer) you can use this app: https://play.google.com/store/apps/details?id=pl.effisoft.rpicamviewer2. You can also open gstreamer preview from your code using following code:

Intent intent = new Intent("pl.effisoft.rpicamviewer2.PREVIEW");
int camera =0;

//--------- Basic settings
intent.putExtra("full_screen", true);

intent.putExtra("name"+camera, "My pipeline name");
intent.putExtra("host"+camera, "192.168.0.1");
intent.putExtra("port"+camera, 5000);
intent.putExtra("description"+camera, "My pipeline description");
intent.putExtra("uuid"+camera, UUID.randomUUID().toString() );
intent.putExtra("aspectRatio"+camera, 1.6);
intent.putExtra("autoplay"+camera, true);

//--------- Enable advanced mode
intent.putExtra("advanced"+camera, true);   //when advanced=true, then     custom_pipeline will be played
                                        //when advanced=false, then pipeline will be generated from host, port (use only for backward compatibility with previous versions)
intent.putExtra("custom_pipeline"+camera, "videotestsrc ! warptv ! autovideosink");

//--------- Enable application extra features
intent.putExtra("extraFeaturesEnabled"+camera, false);

//--------- Add autoaudiosink to featured pipeline
intent.putExtra("extraFeaturesSoundEnabled"+camera, false);

//--------- Scale Video Stream option
intent.putExtra("extraResizeVideoEnabled"+camera, false);
intent.putExtra("width"+camera, 320);       //used only when extraResizeVideoEnabled=true
intent.putExtra("height"+camera, 200);      //used only when extraResizeVideoEnabled=true

//--------- Add plugins
ArrayList<String> plugins = new ArrayList<String>();
intent.putExtra("plugins"+camera, plugins);

intent.setPackage("pl.effisoft.rpicamviewer2");
startActivityForResult(intent, 0);

Use gstreamer for it.

I have used gstreamer at beagleboard which has 1GHz processor for taking image from 2 cameras in 30 fps with very low CPU processing power.

Gstreamer able to merge images, add strings, change formats. And presents you what you want easily in stream. The only thing you need to do is adding black boxes each other.

You can add blackboxes with both dynamically and statically.

If you are not going to change your stream depends on input at your program I suggest to use static one. But I am not sure if it works at android..
