At the end of a streaming session, we used to put up an offline graphic, a short loop or solid picture, to let people know that the player was working, but no one was broadcasting. We will soon be using multiple encoders at different times and it will be tricky to keep track of who is going to put up the offline graphic. Is there a way to have Wowza display a solid image whenever there is no encoder sending it a stream. So as soon as the encoder is shut down, it displays a graphic. When an encoder connects, the graphic is replaced by a stream.
I am running Wowza 4.0 perpetual self hosted (mainly LAN streaming) and I do have the transcoder addon.
