Letsrobot.tv / Run My Robot Overlay Guide

Both of these methods expect a PNG image with transparency to be the same size as your video feed ( 640x480 by default ). It is possible to blend images at different resolutions with alternate commands but beyond the scope of this document.

Static video overlay

Requires no modification to FFMPEG
Add overlayCommand and change the videoCommandLine in send_video.py:

staticOverlayCommand = '-f image2 -i /home/pi/runmyrobot/images/hud.png -filter_complex "[0:v]format=argb,geq=r=\'r(X,Y)\':g=\'g(X,Y)\':b=\'b(X,Y)\':a=\'0.7*alpha(X,Y)\'[overlay]; [1:v][overlay]overlay"'

I tried streaming with FFmpegOut in the following steps.

Modify the following lines in CameraCapture.cs

  _session = FFmpegSession.Create(
    gameObject.name,

	#!/bin/bash

	mkdir postgres
	cd postgres

	docker volume create --driver local --name=pgvolume
	docker volume create --driver local --name=pga4volume

	docker network create --driver bridge pgnetwork
