How to utilize In-Memory Processing while live capture

[SinghNanak]

In my application I have to live capture and analyse packets 24x7, I have noticed that my size of temp folder has increased due to .pcapng being saved there. I have read Dumpcap's and Tshark's documentation and there is a way to pipe packets directly from dumpcap to tshark without being saved on disk, but how to utilize it with pyshark.
