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>
