I’ve build a prototype Bazel-buildable monorepo for Jitsi (the Java part) to make it much nicer to work with.
It can build videobridge from source in a single step with JNI libraries and built-in usrsctp. For more information have a look at the detailed README. Sadly I don’t really have much time to push it further and that would also be wasteful if it’s not adopted. I’m happy to answer questions if you have any.
