How can I know which version of WebRTC did libjingle_peerconnection_so.so build from ?

Hi,buddies

The google store detects that I’m using a vulnerable versions of WebRTC use usrsctp,however, usrsctp is not built into libjingle_peerconnection_so.so because I’v dissalbed these features in WebRTC.gni.

1) rtc_enable_sctp=false

2) rtc_build_usrsctp=false

As usrsctp is not built,so how does google store dectect that I’m using a vulnerable versions of WebRTC use usrsctp ??

So I have several questions about this

Question1：

how does google store dectect that I’m using a vulnerable versions of WebRTC use usrsctp ?

– by scanning the symbols in .so ?

– by scanning the meta infos ?

Question2:

Is there a way to know the version of WebRTC that libjingle_peerconnection_so.so is built from ?

In other words,given a specific so file libjingle_peerconnection_so.so ,How can I know that it’s built from M91 or M102 ?

Here is the FAQ from google.
