+Subject: [PATCH] qtdemux: emit no-more-pads after pruning old pads
+
+If we don't do that, clients can rely on this signal to see the final pad
+topology but it won't be the real one as some of them will disappear after
+emitting that signal. This can happen after injecting a different init segment.
