From 4f117323b8d4c89e5507db008a6a9275c64883c0 Mon Sep 17 00:00:00 2001 From: Matthew Waters Date: Thu, 13 Jun 2013 16:04:40 +1000 Subject: [PATCH] [705/906] x11: don't shutdown in _finalize The window's loop could be still running when _finalize is called and if we destroy the display connection it will never be closed. Add _open and _close vfuncs to GstGLWindow so that subclasses can start up and shutdown at the right time. --- gst-libs/gst/gl/gstglwindow.c | 52 ++++----- gst-libs/gst/gl/gstglwindow.h | 3 + gst-libs/gst/gl/x11/gstglwindow_x11.c | 193 ++++++++++++++++++---------------- 3 files changed, 124 insertions(+), 124 deletions(-) diff --git a/gst-libs/gst/gl/gstglwindow.c b/gst-libs/gst/gl/gstglwindow.c index 858c2f1..5488a6c 100644 --- a/gst-libs/gst/gl/gstglwindow.c +++ b/gst-libs/gst/gl/gstglwindow.c @@ -160,6 +160,7 @@ static void gst_gl_window_finalize (GObject * object) { GstGLWindow *window = GST_GL_WINDOW (object);
