Library for parsing tcpdump in realtime with the ability to decrypt SSL?

Question

Traffic analysis

I'm looking for a library or program to analyze network traffic in real time. Interested in HTTP/HTTPS messages. Ability to decrypt SLL traffic using SSLKEYLOGFILE.

I tried writing tcpdump to .pcap and reading it with python under MacOS, I tried several libraries to parse pcap - but they have some difficulties with recognizing packets - everything is marked as Other (tried scapy, dpkt).

Proxy server with its own certificate is not suitable, since there is no way to configure it correctly in the system.
