The cause of this issue is that when set the *.lib files required for linking gstreamer as an arguments to link.exe, that passing the file name instead of the full...
#368 introduced a device monitor, but it is only enumerating devices. We are not listening to device changes yet.
Running https://ferjm.github.io/samples/src/content/datachannel/basic/ on Servo shows the following warning: `** (:47792): WARNING **: 15:21:30.553: Error sending data on stream 11: (22) Invalid argument` It seems to come from https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/blob/c1b8802c71d34e3d32bf83161329449624376713/ext/sctp/sctpassociation.c#L520
