It is not possible from gst-launch-1.0, here's a python example, though I'm not sure what is needed to make sure foreign window render will work.


import gigi.require_versions({"Gst": "1.0", "GstVideo": "1.0"})from gi.repository import Gst, GstVideoimport time

Gst.init(None)p = Gst.parse_launch("videotestsrc ! ximagesink name=sink")s = p.get_by_name("sink")
GstVideo.VideoOverlay.set_window_handle(s, 0x1000022)p.set_state(Gst.State.PLAYING)time.sleep(10)p.set_state(Gst.State.NULL)
