From 2e23effc15fdf59b46a7693a38be6a2b3a2c8cf8 Mon Sep 17 00:00:00 2001 From: Johan Dahlin Date: Tue, 23 Nov 2004 10:16:58 +0000 Subject: [PATCH] Use gst.element_factory_make in play example Original commit message from CVS: * examples/gst/play.py: * gst/gst-types.defs: * gst/gst.override: * testsuite/Makefile.am: * testsuite/common.py: * testsuite/event.py: * testsuite/test_event.py: Use gst.element_factory_make in play example Use boxed instead of pointer for gst.Event, it was such an ugly hack. Ref the event when sending using gst.element_send_event.
