[Experimental Feature] Delete Lazy Stream

[Keukhan]

When the system performance is insufficient, the memory continuously increases and the system is forced to shut down.
In particular, it uses a lot of CPU or GPU resources in the decoding/encoding. In this case, data is continuously accumulated in the queue of a specific stream. and when the queue exceeds the threshold, I define this as Lazy Stream.

I decided to provide a method to forcibly delete the stream to prevent memory increase caused by Lazy Stream.
See the settings below. When a lazy stream continue for the time defined by DeleteLazyStreamTimeout, the stream is forcibly deleted and the memory is cleaned up.

server.xml

<Modules>
		<Recovery>
		<!--  
		If the packet/frame queue is exceed for a certain period of time(ms), it will be automatically deleted. 
		If this value is set to zero, the stream will not be deleted. 
		-->
			<DeleteLazyStreamTimeout>10000</DeleteLazyStreamTimeout>
		</Recovery>
</Modules>

If you are experiencing forced shutdown due to memory increase as above, please test it out and share if you have a better idea.

Thanks.
