I am creating a 1-to-many webcam chat application. The publisher part is all done and working. But the viewers part has some really weird quirks. I have tried all kinds of fixes, but nothing seems to work. The problem is in IE only and not in other browsers. There it is working properly. The problem is as follows. When someone is publishing a webcam, a viewer can watch the webcam. When the publisher decides to stop publishing, the NetStream is closed by NetStream.close() on the publishers part. The viewer gets a notification by the NetStatusEvent of NetStream.Play.Stop and NetStream.Play.UnpublishNotify. After the buffer has become empty. Nothing can't be viewed anymore, except the last frame. This is as expected. However, when the publisher decides to start publishing again, the viewer gets a notification of NetStream.Play.Start and NetStream.Play.PublishNotify. In Chrome and Firefox, the viewer can view the livestream again. However in IE the notifications are received, but the viewer still sees the last frame and doesn't see the stream anymore. Does anyone know whatthis could be?
