Embedding Logo
Embedding logo on a live stream
FFmpeg also provides complex a/v filters which allow us to manipulate audio and video in a rather complex manner. We can use this to embed a png image as a brand logo on the live stream. Here we re-encode the stream to have the logo in each video frame and then package it along with the audio stream before publishing it to Red5 Pro.
Sample command to add a logo to a live stream to a Red5 Pro live stream and re-transmit it as a new stream
