The project is very simple, consist only in add a png logo to my Youtube stream.
I have a raspberry with PiCamera and ffmpeg library installed, now I can transmit correctly the stream to youtube but I don't find the right method to add a watermark.

pretty simple task i can make a simple script that will overlay your need png watermark over your stream, feel free to check my profile for past projects and reviews.
Since you are using -vcodec copy it's not possible to add watermark, so you have to reencode your stream so this will put some load on your machine (it might require some tuning to have it smooth)
