There are problems with global shared state and no API stability guarantees, and we can't rely on distros shipping the fixes we need. Both firefox and Chrome bundle their own copies too. Imported from https://github.com/sctplab/usrsctp, commit 547d3b46c64876c0336b9eef297fda58dbe1adaf Date: Thu Jul 23 21:49:32 2020 +0200 Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/870 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1465>
