The RTP stream output cannot second guess what you're trying to do. If you 
tell it to destroy an ES, it removes the RTP session associated with it. 
That's normal behavior.

There is no way to signal media parameters change dynamically with RTSP/1.0. 
There simply is not. If you need to add/remove ES dynamically, use RTP/TS 
encapsulation, but that will only work if your ES are supported by TS.

If there's a bug, it's in the MP4 demux. I am not familiar with it though. It 
might be that it needs to destroy/recreate the ES if the codec requires it.
