From a1c34b540735a7a23b15cdb77ecba1b28adb93ee Mon Sep 17 00:00:00 2001 From: Michael Olbrich Date: Wed, 5 Jun 2013 16:32:30 +0200 Subject: [PATCH] v4l2: make sure the element is not deleted before the pool The pool accesses data from the v4l2object so it must exist at least as long as the pool. Refcount the element which controls the object live-time. https://bugzilla.gnome.org/show_bug.cgi?id=701650 --- sys/v4l2/gstv4l2bufferpool.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/sys/v4l2/gstv4l2bufferpool.c b/sys/v4l2/gstv4l2bufferpool.c index 34a444b39e..3ead390968 100644 --- a/sys/v4l2/gstv4l2bufferpool.c +++ b/sys/v4l2/gstv4l2bufferpool.c @@ -1017,6 +1017,8 @@ gst_v4l2_buffer_pool_finalize (GObject * object) gst_object_unref (pool->allocator); g_free (pool->buffers); + gst_object_unref (pool->obj->element); + G_OBJECT_CLASS (parent_class)->finalize (object); } @@ -1070,6 +1072,8 @@ gst_v4l2_buffer_pool_new (GstV4l2Object * obj, GstCaps * caps) gst_buffer_pool_config_set_params (s, caps, obj->sizeimage, 2, 0); gst_buffer_pool_set_config (GST_BUFFER_POOL_CAST (pool), s); + gst_object_ref (obj->element); + return GST_BUFFER_POOL (pool); /* ERRORS */ -- 2.34.1
