When two people are finishing a video session and one of the them disconnects the image freezes on the other side. Additionally to this I'm trying to display a text message saying that the user has ended the video call. Is there a way to achieve this through the Red5 server config by changing any of the files? or do I need to modify the Red5 plugin? I tried the last one but seems that the video browser class doesn't even display a fixed text when wrapping a video session. Has anyone achieved this solution?
