Wow - this is a very obscure feature of the RTSP protocol: sending an "ANNOUNCE" command from the server to the client. This is the first time that I have ever heard of a server that does this. (Note, BTW, that the "ANNOUNCE" command - because it was poorly specified and rarely used - has been removed entirely from the proposed "RTSP 2.0" update to RTSP.) > The change in Payload would cause an error normally - do you think it is > possible for Live555 to be adjusted to handle this payload change mid stream? Yes, conceivably. However, adding support for a feature like this is not something that we would do for free. If anyone (e.g., American Dynamics, which manufacturers the "VideoEdge NVR") is interested in paying for this, please let me know (by separate email). Also, you didn't say anything about which client application (using the "LIVE555 Streaming Media" code) you are using. Note that even if our library were updated to support this obscure server->client "ANNOUNCE" command, your client application would also need to be updated to handle this (e.g., by using our library to send out new RTSP "SETUP" and "PLAY" commands, reopen (& resize) the video display window, etc.).
